Poor performances on tables FAGL_011ZC, FAGL_011PC and FAGL_011VC

We note from some time on a very very poor performances of some programme accessing these tables.
The tables are very small, still standard.
We see these tables does not have particular indexes, and their buffering is "allowed but disabled".
In you opinion can we activate the buffering of these tables ? Are there controindications ?
Our system is ECC5 quite aligned as SP level.

Client is looking upon TDMS (Test Data Migration Server) to replicate the PRD data into lower systems.

  • Instability and Poor Performance with 11 11/11 and 11.1

    I've upgraded an OpenSolaris install to Solaris 11.1 over time and ever since I hit Solaris 11 11/11 and Solaris 11.1 my system has been unstable and slow (especially ZFS and GDM (which I had to disable in 11/11.1 because it was using too much CPU)). Whenever I shut down in Solaris 11/11.1 it causes a kernel panic. I run this command to shutdown:
    /usr/sbin/shutdown -y -g 60 -i 5
    and it causes this (then the system auto-restarts -- it never completes the shutdown):

    What could be causing all these issues -- why are the OpenSolaris and Solaris 11 Express installs faster/more stable? Is it a hardware incompatibility issue? How can I determine the root cause and fix it?
    Thanks.

    Alan, if the cause is a 5400 RPM drive, I'm not sure why when I boot into my older BEs for Opensolaris/Solaris 11 Express/OpenIndiana I see much better ZFS performance. After I upgraded to 11.1 I noticed slowness and went back to my old Boot Environments and generated the dd read/write speeds I put in the top post, so it's not like any of the hardware changed during that hour I was bench marking between BEs nor did the amount of space used in my zpool change (it is mostly empty and I deleted everything that I wrote with dd after each test).

  • Poor performance in select on CLOB (and actually anything not kept inrow)

    Hello,
    Creating a table with RAW(16) as primary key (GUID), CLOB
    and inserting some hundred-thousands up to 10 million records.
    Selects on this table are a randomly chosen (by sample query) 500-1000 ids from the table, then fetching
    the CLOB data, takes about 16-20 secs for 1000 records.
    Anyone have a clue on how to make these kind of selects faster. We are aiming at 5 seconds top for this kind of query.
    Or is it too much to expect ?
    The select itself is done as join which temporary table containing the id (which is better than just using the IN operator).
    Regards,
    Rani

    hi
    I alsow have a problem when i work with clobs , even doing the 10046 trace , there is still time un-accounted for , see my test case at [clob test case|http://forums.oracle.com/forums/message.jspa?messageID=3474400#3474400] although its just inserting/appending the clob.

  • Poor performance with 100,000+ songs and 20+ smart playlists

    Collecting music is my thing. I buy and rip a dozen CDs a week in both Apple Lossless and AAC format. I listen to Apple Lossless on my home systems and sync the AAC versions to my iPhone for car listening.
    I have the fastest computer Apple has ever made, an 8-core 3.2ghz Xeon Mac Pro. I have multiple eSATA 1.5TB drives with a RocketRaid Mini-SAS to PCI Express SATA II controller. My iTunes directory and music are all on external drives.
    Problem is, whenever I'm tagging tracks, deleting tracks, or even just changing the name of a song, I constantly get the spinning beach ball for a couple of seconds before control returns to me. This is highly annoying. I understand with every change, iTunes probably has to check to update all my Smart Playlists (I need to keep Live Updating turned on), but with an 8-core Xeon, why is this an issue? This machine can edit HD video but can't handle a big chunk of text processing? Is iTunes not multi-threaded to use all 8 cores?
    If anyone can help me speed up my process, I would save probably an hour a day.

    hello
    i dont have an answer to the question since i am struggeling with a similar problem. my library is on an external FW 800, 500 GB+. I have done some test and i found that itunes never uses more than 20% of my CPU power, even if itunes is all the OS is handling.
    so my conclusion is, that the priority level is not high enough, cos i believe as you also prove with your mac pro machine, the power isnt the issue, but the priority set for the CPU to handle itunes.
    i read that the only way to change prio levels in os x is to use smtg called "renice" and fool around in terminal. i am too novice to try anything like that, so i m left with the beachball and hope for an itunes pro or a support for large libs in an update
    cheers

  • Poor performance of the BDB cache

    I'm experiencing incredibly poor performance of the BDB cache and wanted to share my experience, in case anybody has any suggestions.
    Overview
    Stone Steps maintains a fork of a web log analysis tool - the Webalizer (http://www.stonesteps.ca/projects/webalizer/). One of the problems with the Webalizer is that it maintains all data (i.e. URLs, search strings, IP addresses, etc) in memory, which puts a cap on the maximum size of the data set that can be analyzed. Naturally, BDB was picked as the fastest database to maintain analyzed data on disk set and produce reports by querying the database. Unfortunately, once the database grows beyond the cache size, overall performance goes down the drain.
    Note that the version of SSW available for download does not support BDB in the way described below. I can make the source available for you, however, if you find your own large log files to analyze.
    The Database
    Stone Steps Webalizer (SSW) is a command-line utility and needs to preserve all intermediate data for the month on disk. The original approach was to use a plain-text file (webalizer.current, for those who know anything about SSW). The BDB database that replaced this plain text file consists of the following databases:
    sequences (maintains record IDs for all other tables)
    urls -primary database containing URL data - record ID (key), URL itself, grouped data, such as number of hits, transfer size, etc)
    urls.values - secondary database that contains a hash of the URL (key) and the record ID linking it to the primary database; this database is used for value lookups)
    urls.hits - secondary database that contains the number of hits for each URL (key) and the record ID to link it to the primary database; this database is used to order URLs in the report by the number of hits.
    The remaining databases are here just to indicate the database structure. They are the same in nature as the two described above. The legend is as follows: (s) will indicate a secondary database, (p) - primary database, (sf) - filtered secondary database (using DB_DONOTINDEX).
    urls.xfer (s), urls.entry (s), urls.exit (s), urls.groups.hits (sf), urls.groups.xfer (sf)
    hosts (p), hosts.values (s), hosts.hits (s), hosts.xfer (s), hosts.groups.hits (sf), hosts.groups.xfer (sf)
    downloads (p), downloads.values (s), downloads.xfer (s)
    agents (p), agents.values (s), agents.values (s), agents.hits (s), agents.visits (s), agents.groups.visits (sf)
    referrers (p), referrers.values (s), referrers.values (s), referrers.hits (s), referrers.groups.hits (sf)
    search (p), search.values (s), search.hits (s)
    users (p), users.values (s), users.hits (s), users.groups.hits (sf)
    errors (p), errors.values (s), errors.hits (s)
    dhosts (p), dhosts.values (s)
    statuscodes (HTTP status codes)
    totals.daily (31 days)
    totals.hourly (24 hours)
    totals (one record)
    countries (a couple of hundred countries)
    system (one record)
    visits.active (active visits - variable length)
    downloads.active (active downloads - variable length)
    All these databases (49 of them) are maintained in a single file. Maintaining a single database file is a requirement, so that the entire database for the month can be renamed, backed up and used to produce reports on demand.
    Database Size
    One of the sample Squid logs I received from a user contains 4.4M records and is about 800MB in size. The resulting database is 625MB in size. Note that there is no duplication of text data - only nodes and such values as hits and transfer sizes are duplicated. Each record also contains some small overhead (record version for upgrades, etc).
    Here are the sizes of the URL databases (other URL secondary databases are similar to urls.hits described below):
    urls (p):
    8192 Underlying database page size
    2031 Overflow key/data size
    1471636 Number of unique keys in the tree
    1471636 Number of data items in the tree
    193 Number of tree internal pages
    577738 Number of bytes free in tree internal pages (63% ff)
    55312 Number of tree leaf pages
    145M Number of bytes free in tree leaf pages (67% ff)
    2620 Number of tree overflow pages
    16M Number of bytes free in tree overflow pages (25% ff)
    urls.hits (s)
    8192 Underlying database page size
    2031 Overflow key/data size
    2 Number of levels in the tree
    823 Number of unique keys in the tree
    1471636 Number of data items in the tree
    31 Number of tree internal pages
    201970 Number of bytes free in tree internal pages (20% ff)
    45 Number of tree leaf pages
    243550 Number of bytes free in tree leaf pages (33% ff)
    2814 Number of tree duplicate pages
    8360024 Number of bytes free in tree duplicate pages (63% ff)
    0 Number of tree overflow pages
    The Testbed
    I'm running all these tests using the latest BDB (v4.6) built from the source on Win2K3 server (release version). The test machine is 1.7GHz P4 with 1GB of RAM and an IDE hard drive. Not the fastest machine, but it was able to handle a log file like described before at a speed of 20K records/sec.
    BDB is configured in a single file in a BDB environment, using private memory, since only one process ever has access to the database).
    I ran a performance monitor while running SSW, capturing private bytes, disk read/write I/O, system cache size, etc.
    I also used a code profiler to analyze SSW and BDB performance.
    The Problem
    Small log files, such as 100MB, can be processed in no time - BDB handles them really well. However, once the entire BDB cache is filled up, the machine goes into some weird state and can sit in this state for hours and hours before completing the analysis.
    Another problem is that traversing large primary or secondary databases is a really slow and painful process. It is really not that much data!
    Overall, the 20K rec/sec quoted above drop down to 2K rec/sec. And that's all after most of the analysis has been done, just trying to save the database.
    The Tests
    SSW runs in two modes, memory mode and database mode. In memory mode, all data is kept in memory in SSW's own hash tables and then saved to BDB at the end of each run.
    In memory mode, the entire BDB is dumped to disk at the end of the run. First, it runs fairly fast, until the BDB cache is filled up. Then writing (disk I/O) goes at a snail pace, at about 3.5MB/sec, even though this disk can write at about 12-15MB/sec.
    Another problem is that the OS cache gets filled up, chewing through all available memory long before completion. In order to deal with this problem, I disabled the system cache using the DB_DIRECT_DB/LOG options. I could see OS cache left alone, but once BDB cache was filed up, processing speed was as good as stopped.
    Then I flipped options and used DB_DSYNC_DB/LOG options to disable OS disk buffering. This improved overall performance and even though OS cache was filling up, it was being flushed as well and, eventually, SSW finished processing this log, sporting 2K rec/sec. At least it finished, though - other combinations of these options lead to never-ending tests.
    In the database mode, stale data is put into BDB after processing every N records (e.g. 300K rec). In this mode, BDB behaves similarly - until the cache is filled up, the performance is somewhat decent, but then the story repeats.
    Some of the other things I tried/observed:
    * I tried to experiment with the trickle option. In all honesty, I hoped that this would be the solution to my problems - trickle some, make sure it's on disk and then continue. Well, trickling was pretty much useless and didn't make any positive impact.
    * I disabled threading support, which gave me some performance boost during regular value lookups throughout the test run, but it didn't help either.
    * I experimented with page size, ranging them from the default 8K to 64K. Using large pages helped a bit, but as soon as the BDB cached filled up, the story repeated.
    * The Db.put method, which was called 73557 times while profiling saving the database at the end, took 281 seconds. Interestingly enough, this method called ReadFile function (Win32) 20000 times, which took 258 seconds. The majority of the Db.put time was wasted on looking up records that were being updated! These lookups seem to be the true problem here.
    * I tried libHoard - it usually provides better performance, even in a single-threaded process, but libHoard didn't help much in this case.

    I have been able to improve processing speed up to
    6-8 times with these two techniques:
    1. A separate trickle thread was created that would
    periodically call DbEnv::memp_trickle. This works
    especially good on multicore machines, but also
    speeds things up a bit on single CPU boxes. This
    alone improved speed from 2K rec/sec to about 4K
    rec/sec.Hello Stone,
    I am facing a similar problem, and I too hope to resolve the same with memp_trickle. I had these queries.
    1. what was the % of clean pages that you specified?
    2. What duration were you clling this thread to call memp_trickle?
    This would give me a rough idea about which to tune my app. Would really appreciate if you can answer these queries.
    Regards,
    Nishith.
    >
    2. Maintaining multiple secondary databases in real
    time proved to be the bottleneck. The code was
    changed to create secondary databases at the end of
    the run (calling Db::associate with the DB_CREATE
    flag), right before the reports are generated, which
    use these secondary databases. This improved speed
    from 4K rec/sec to 14K rec/sec.

  • URGENT: Migrating from SQL to Oracle results in very poor performance!

    *** IMPORTANT, NEED YOUR HELP ***
    Dear, I have a banking business solution from Windows/SQL Server 2000 to Sun Solaris/ORACLE 10g migrated. In the test environment everything was working fine. On the production system we have very poor DB performance. About 100 times slower than SQL Server 2000!
    Environment at Customer Server Side:
    Hardware: SUN Fire 4 CPU's, OS: Solaris 5.8, DB Oracle 8 and 10
    Data Storage: Em2
    DB access thru OCCI [Environment:OBJECT, Connection Pool, Create Connection]
    Depending from older applications it's necessary to run ORACLE 8 as well on the same Server. Since we have running the new solution, which is using ORACLE 10, the listener for ORACLE 8 is frequently gone (or by someone killed?). The performance of the whole ORACLE 10 Environment is very poor. As a result of my analyse I figured out that the process to create a connection to the connection pool takes up to 14 seconds. Now I am wondering if it a problem to run different ORACLE versions on the same Server? The Customer has installed/created the new ORACLE 10 DB with the same user account (oracle) as the older version. To run the new solution we have to change the ORACLE environment settings manually. All hints/suggestions to solve this problem are welcome. Thanks in advance.
    Anton

    On the production system we have very poor DB performanceHave you identified the cause of the poor performance is not the queries and their plans being generated by the database?
    Do you know if some of the queries appear to take more time than what it used to be on old system? Did you analyze such queries to see what might be the problem?
    Are you running RBO or CBO?
    if stats are generated, how are they generated and how often?
    Did you see what autotrace and tkprof has to tell you about problem queries (if in fact such queries have been identified)?

  • N580GTX Poor Performance

    I recently bought a 580GTX Lightning and out of the box I was experiencing fairly poor performance especially in DX11 games and benchmarks. This was with the MSI OC clocks (832Mhz core etc). I down-clocked to standard 580 values and performance immediately increased to levels you would expect a 580 card to be capable of. Seemed at the time as if the GPU voltage was set too low...
    In playing around with the card, I flipped the BIOS dipp switch to the LN2 setting and found that the clock settings were at (by default) the standard 580GTX settings. Performance was in this case again poor despite the lower clocks. I then increased clocks to the MSI OC values and performance jumped again to where a 580GTX card should be. Odd.
    Next I flipped the Bios back to the original, restarted and left the OC at the MSI values. Performance remains at most excellent.
    At the moment it seems I get good performance when I am using Afterburner and have the "Apply Overclocking at System Startup" option applied.
    My question is why is this? Will this card only work correctly when used in conjunction with Afterburner? Any thoughts on why this is?
    GPU BIOS: 70.10.17.00.06
    PSU: Silverstone Strider Gold 750W
    Nvidia Drivers: 270.61

    AB is just a software tool that allows you to manipulate the clocks and voltages, easily. Nothing more.

    That setting will apply an Overclock that you manually set and then saved as a user profile within Afterburner. If you did not save a user profile, then it will be the same settings as what your card's factory clocks are. i.e. it will not apply anything.

    Poor performance is relative. This needs to be quantified and a measuring standard is needed, as well as comparisons to the same or similar cards to establish a consistent baseline.

    If I run just the select portion of the statement, using bind values from exe #2, I get small number of gets (< 10), and < 0.1 secs elapsed.
    If I make the insert into an empty, non-partitioned table, I get :

    This problem is part of testing of a database upgrade and country go-live. On a 10.2.0.3 test system (non-RAC), the same insert/select - using the real WF_Item_Attributes_Value table takes :

    total        2      0.00       0.10         10         27        136          25So I'm struggling to understand why the performance on the 10.2.0.4 RAC system is so much worse for this query, and why it's doing so many gets. Suggestions, thoughts, ideas welcomed.
    I've verified system level things - CPUs weren't/aren't max'd out, no significant paging/swapping activity, run queue not long. AWR report for the time period shows nothing unusual.
    further info on the objects concerned:
    query source table :
    WF_Item_Attributes_PK : unique index on Item_Type, Name. Index has 144 blocks, non-partitioned
    WF_Item_Attributes tbl : non-partitioned, 160 blocks
    insert destination table:
    WF_Item_Attribute_Values:
    range partitioned on Item_Type, and hash sub-partitioned on Item_Key
    both executions of the insert hit the partition with the most data : 127,691 blocks total ; 8 sub-partitions with 15,896 to 16,055 blocks per sub-partition.
    WF_Item_Attribute_Values_PK : unique index on columns Item_Type, Item_Key, Name. Range/hash partitioned as per table.
    Bind values:
    exe #1 : Item_Type (:B1) = OEOH, Item_Key (:B2) = 1048671
    exe #2 : Item_Type (:B1) = OEOL, Item_Key (:B2) = 4253168
    number of rows in WF_Item_Attribute_Values for Item_Type = OEOH : 1132587
    number of rows in WF_Item_Attribute_Values for Item_Type = OEOL : 18763670
    The non-RAC 10.2.0.3 test system (clone of Production from last night) has higher row counts for these 2.

    hi Sven,
    Thanks for your input.
    1) I guess so, but I haven't lifted the lid to delve inside the form as to which one. I don't think it's the cause though, as I got poor performance running the insert statement with my own value (same statement, using my own bind value).
    2) In every execution plan I've seen, checked, re-checked, it uses a range scan on the primary key. It is the most efficient I think, but the source table is small in any case - table 160 blocks, PK index 144 blocks. So I think it's the partitioned destination table that's the problem - but we only see this issue on the 10.2.0.4 pre-production (RAC) system. The 10.2.0.3 (RAC) Production system doesn't have it. This is why it's so puzzling to me - the source table read is fast, and does few gets.
    3) table storage details below - the Item_Types being used were 'OEOH' (fast execution) and 'OEOL' (slow execution). Both hit partition WF_ITEM49, hence I've only expanded the subpartition info for that one (there are over 600 sub-partitions).

  • Poor performance and overheat

    Story
    I've been using arch for the past four months, dual booting with my old Windows XP. As I'm very fond of Flash games and make my own programs with a cross-platform language, I've found few problems with the migration. One of them was the Adobe Flash Player performance, which was stunningly bad. But everyone was saying that was normal, so I left it as is.
    However, one special error always worried me: a seemingly randomly started siren sound coming from the motherboard speaker. Thinking it was a alarm about some fatal kernel error, I had been solving it mostly with reboots.
    But then it happened. While playing a graphics intensive game on Windows quickly after rebooting from Arch, the same siren sound started. It felt like a slap across the face: it was not a kernel error, it was an motherboard overheat alarm.
    The Problem
    Since the computer was giving overheat signs, I started looking at things from another angle. I noticed that some tasks take unusually long times in Arch (i.e.: building things from source; Firefox / OpenOffice startup; any graphics intensive program), specially from the Flash Player.
    A great example is the game Penguinz, that runs flawlessly in Windows but is unbearably slow in Arch. So slow that it alone caused said overheat twice. And trying to record another flash game's record using XVidCap things went so bad that the game halved the FPS and started ignoring key presses.
    Tech Info
    Dual Core 3.2 processor
    1 gb RAM
    256 mb Geforce FX 5500 video card
    Running Openbox
    Using proprietary NVIDIA driver
    TL;DR: poor performance on some tasks. Flash Player is so slow that overheats CPU and makes me cry. It's fine on Windows.
    Off the top of my head I can think up some reasons: bad video driver, unwanted background application messing up, known Flash Player performance problems and Actionscript Linux/Arch-only bug.
    Where do you think is the problem?

    jwcxz wrote:Have you looked at your process table for any program with abnormal CPU usage?  That seems like the logical place to start.  You shouldn't be getting poor performance in anything with that system.  I have a 2.0GHz Core 2 Duo and an Intel GMA 965 and I've never had any problems with Flash.  It's much better than it used to be.
    Pidgin scared me for a while because it froze for no apparent reason. After fixing this, the table contains this two guys here:
    %CPU
    Firefox: 80%~100%
    X: 0~20%
    Graphic intensive test, so I think the X usage is normal. It might be some oddity at the Firefox+Linux+Flash sum, maybe a conflict. I'll try another browser.
    EDIT:
    Did a Javascript benchmark to test both systems and browsers.
    Windows XP + Firefox = 4361.4ms
    Arch + Firefox = 5146.0ms
    So, it's actually a lot slower without even taking Flash into account. If someone knows a platform-independent benchmark to test both systems completely, and not only the browser, feel free to point out.
    I think that something is already wrong here and the lack of power saving systems only aggravated the problem, causing overheat.
    EDIT2:
    Browser performance fixed: migrated to Midori. Flash stills slower than on Windows, but now it's bearable. Pretty neat browser too, goes better with the Arch Way. It shouldn't fix the temperature, however.
    Applied B's idea, but didn't test yet. I'm not into the mood of playing flash games for two straight hours today.

  • Poor performance and voltage fluctuation.

    I'm running two 280x in crossfire which I upgraded from two 6970's.   When I'm playing DayZ my FPS never go above 30 FPS.  With my 6970's I was well into the 70's.  I never changed my video settings when I went from the 6970's to the 280X's.   For the most part I have a lot of the graphics low or disabled.   Borderlands 2 is a nightmare on the 280X.  I drop down into 10 fps area and this has never happened with on my 6970's.
    During games my core voltage fluctuates between 500mhz and 1020mhz during game play.  I have ULPS disable as well.
    My power supply is an Antec HCG-900.
    Happened on all these drivers 14.4, 14.6 Beta, and 14.6 RC (currently installed).

  • Invalid block count and poor performance

    Hi - Can anyone help?
    Running an early 2011 13' MBP on ML. For a year - 18 months I've noticed poor performance at times, consistently slow boot (sometimes 5 minutes to usable), occasional lockups and spotlight often reindexes itself and slows the system (much more than my previous MBP), I can't see anything that triggers it. I'm also getting recurring errors in Disk Utility of 'Invalid block count', every time I'll repair the disk (booting into recovery), but after a month of use the error will reappear. About three months ago I erased and reinstalled ML, some of my data was moved over in Time Machine but I didn't restore from it. The erase and reinstall hasn't made any difference and I'm still seeing the same issues. Hard disk SMART status appears to be fine.
    Can anyone recommend any troubleshooting steps? I'm not sure what else to do, still under Applecare and was thinking maybe the HD isn't working correctly?
    Cheers!

  • Safari hangs and poor performance in MBPR (Mid 2012)

    Safari hangs and poor performance in MBPR (Mid 2012)? OS X 10.10.2 is up to date

    Please answer as many of the following questions as you can. You may already have answered some of them. In that case, there's no need to repeat the answers.
    Back up all data before making any changes.
    Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If not, do that now and see whether there's any change.
    If your browser is Safari, then from the Safari menu bar, select
              Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
    and confirm. If the Downloads button (with the icon of a downward-pointing arrow) is showing in the toolbar, click it and then click Clear in the box that appears. The download history will be removed. Any change?
    If you're running OS X 10.9 or later, select the Advanced tab in the Preferences window and uncheck the box marked
              Stop plug-ins to save power
    Any change?
    Quit and relaunch the browser. Any change?
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
    If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
    If Parental Controls is active for any user, please turn it off and test. Any change?
    If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
    Follow the instructions in this support article. Any change?
    Open the iCloud preference pane and uncheck the box marked Photos, if it's checked. Any change?
    Are there any other devices on the same network that can browse the Web, and are they affected?
    If you can test Safari on another network, is it the same there?
    If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

  • Crashing and poor performance during playback of a large project.

    Hi,
    I've been a regular user of iMovie for about 3 years and have edited several 50GB+ projects of DV quality footage without too many major issues with lag or 'dropped frames'. I currently have a 80GB project that resides on a 95% full 320GB Firewire 400 external drive that has been getting very slow to open and near impossible to work with.
    Pair the bursting-at-the-seams external drive, with an overburdened 90% full internal drive - the poor performance wasn't to be unexpected. So I bought a 1TB Firewire 400 drive to free up some space on my Mac. My large iTunes library (150GB) was the main culprit and it was quickly moved onto the new drive.
    The iMovie project was then moved onto my Mac's movie folder - I figured that the project needs some "room" to work (not that I really understand how Macs use memory) and that having roughly 80GB free with 1.5GB RAM (which is more than used to have) would make everything just that much smoother.
    Wrong.
    The project opened in roughly the same amount of time - but when I tried to play back the timeline, it plays like rubbish and then after 10-15 secs the Mac goes into 'sleep' mode. The screen goes off, the fans dies down and the 'heartbeat' light goes on. A click of the mouse 'wakes' the Mac only to find that if i try again, I get the same result.
    I've probably got so many variables going on here that it's probably hard to suggest what the problem might be but all I could think of was repairing permissions (which I did and none needed it).
    Stuck on this. Anyone have any advice?

    I understand completely, having worked with a 100 GB project once. I found that getting a movie bloated up to that size was just more difficult with jerky playback.
    I do have a couple of suggestions for you.
    You may need more than that 80GB free space for this movie. Is there any reason you cannot move it to the 1TB drive? If you have only your iTunes on it, you should have about 800 GB free.
    If you still need to have the project on your computer's drive, set your computer to never sleep.
    How close to finishing editing are you with this movie? If you are nearly done except for adding audio clips, you can export (share) it as QuickTime Full Quality movie. The resultant quicktime version of your iMovie will be smaller because it will contain only the clips actually used in the movie, not all the saved whole clips that iMovie keeps as its nondestructive editing feature. The quicktime movie will be one continuous clip, incorporating all your edits and added audio. It CAN be further edited, but you cannot change text of titles already there, or change transitions or remove already added audios.
    I actually do this with nearly every iMovie. I create my movies by first importing videos, then adding still photos, then editing with titles, effects and transitions. I add audio last, and if it becomes too distorted in playback, I export the movie and then continue adding audio clips.
    My 100+ GB movie slimmed down to only 8 GB with this method. (The large size was due to having so many clips. The movie was from VHS footage of my son's little league all-star game, and the video had so many skipped segments that I had to split it into thousands of clips to remove the dropped ones. Very old VHS tape!).
    I haven't upgraded to QT 7.5.5, but I heard that the jerky playback issue is mostly resolved with this new upgrade. I am in mid-project with about 5 iMovies, so I will probably plod along with my work-around method, not wanting to upgrade in the middle of any of them.
    Hope this is helpful to you.

  • Skype crashing and poor performance

    Hello!
    I have a Lumia625 with WP8.1. My problem is that Skype has a really poor performance on my phone. It crashes 6 times out of 10 on startup, and even if I manage to start it, the whole app is slow and laggy. Sometimes I can't even write a message it's so laggy. Video call is absolutely out of the question. It crashes my whole phone. I have no similar problems with other instant messaging apps nor with high-end games. There is something obviously using way more resource in the Skype app than it's supposed to. It's a simple chat program, why would it need so much resource?
    The problem seems to be originating from the lower (512 mb) RAM size of my phone model, because I experienced the same effect with poorly written apps, that don't keep in mind that there are 512 RAM devices, not only 1GB+ ones, and use too much resource.
    Please don't try to suggest to restart/reset the phone, and reinstall the app. Those are already behind me, and they did NOT help the problem. I'm not searching for temporary workarounds.
    Please find a solution for this problem, because it is super annoying, and I can't use Skype, which will eventually result in me leaving Skype.
    Solved!
    Go to Solution.

    When it crashes on startup it goes like:
    I tap the skype tile
    The black screen with the "Loading....." appears (default WP loading screen). Usually this takes longer than it would normally take on any other app.
    For a blink of an eye the Skype gui appears, but it instantly crashes.
    If I can successfully start up the app, it just keeps lagging. I sart to write a message to a contact, and sometimes even the letters don't appear as I touch them, but they appear much later altogether. If I tap the send message button the whole gui freezes (seems like it freezes till the contact gets my message). Sometimes the lag get stronger, and sometimes it almost vanishes, but if I keep making inputs when the lag is strong, sometimes it crashes the whole app.
    When I first installed the app, everything was fine. But after a while this behavior appeared. I reinstalled the app, and it solved the problem temporarily, but after some time the problem re-appeared. I don't know if it's relevant, but there was a time when I couldn't make myself appear online all the time (when the app was not started). In that time I didn't experience the lags and crashes. Anyways, what I'm sure about is that the lags get worse with time. Idk if it's because of use of the app (caching?), or the updates the phone makes to itself (conflict?).
    I will try to reinstall Skype. Probably it will fix it for now. I hope the problem won't appear again.

  • Poor performance with WebI and BW hierarchy drill-down...

    Hi
    We are currently implementing a large HR solution with BW as backend
    and WebI and Xcelcius as frontend. As part of this we are experiencing
    very poor performance when doing drill-down in WebI on a BW hierarchy.
    In general we are experiencing ok performance during selection of data
    and traditional WebI filtering - however when using the BW hierarchy
    for navigation within WebI, response times are significantly increasing.
    The general solution setup are as follows:
    1) Business Content version of the personnel administration
    infoprovider - 0PA_C01. The Infoprovider contains 30.000 records
    2) Multiprovider to act as semantic Data Mart layer in BW.
    3) Bex Query to act as Data Mart Query and metadata exchange for BOE.
    All key figure restrictions and calculations are done in this Data Mart
    Query.
    4) Traditionel BO OLAP universe 1:1 mapped to Bex Data Mart query. No
    calculations etc. are done in the universe.
    5) WebI report with limited objects included in the WebI query.
    As we are aware that performance is an very subjective issues we have
    created several case scenarios with different dataset sizes, various
    filter criteria's and modeling techniques in BW.
    Furthermore we have tried to apply various traditional BW performance
    tuning techniques including aggregates, physical partitioning and pre-
    calculation - all without any luck (pre-calculation doesn't seem to
    work at all as WebI apparently isn't using the BW OLAP cache).
    In general the best result we can get is with a completely stripped WebI report without any variables etc.
    and a total dataset of 1000 records transferred to WebI. Even in this scenario we can't get
    each navigational step (when using drill-down on Organizational Unit
    hierarchy - 0ORGUNIT) to perform faster than minimum 15-20 seconds per.
    navigational step.
    That is each navigational step takes 15-20 seconds
    with only 1000 records in the WebI cache when using drill-down on org.
    unit hierachy !!.
    Running the same Bex query from Bex Analyzer with a full dataset of
    30.000 records on lowest level of detail returns a threshold of 1-2
    seconds pr. navigational step thus eliminating that this should be a BW
    modeling issue.
    As our productive scenario obviously involves a far larger dataset as
    well as separate data from CATS and PT infoproviders we are very
    worried if we will ever be able to utilize hierarchy drill-down from
    WebI ?.
    The question is as such if there are any known performance issues
    related to the use of BW hierarchy drill-down from WebI and if so are
    there any ways to get around them ?.
    As an alternative we are currently considering changing our reporting
    strategy by creating several higher aggregated reports to avoid
    hierarchy navigation at all. However we still need to support specific
    division and their need to navigate the WebI dataset without
    limitations which makes this issue critical.
    Hope that you are able to help.
    Thanks in advance
    /Frank

    Hi Henry, thank you for your suggestions although i´m not agree with you that 20 seconds is pretty good for that navigation step. The same query executed with BEx Analyzer takes only 1-2 seconds to do the drill down.
    Actions
    suppress unassigned nodes in RSH1: Magic!! This was the main problem!!
    tick use structure elements in RSRT: Done it.
    enable query stripping in WebI: Done it.
    upgrade your BW to SP09: Has the SP09 some inprovements in relation to this point ?
    use more runtime query filters. : Not possible. Very simple query.
    Others:
    RSRT combination H-1-3-3-1 (Expand nodes/Permanent Cache BLOB)
    Uncheck prelimirary Hierarchy presentation in Query. only selected.
    Check "Use query drill" in webi properties.
    Sorry for this mixed message but when i was answering i tryied what you suggest in relation with supress unassigned nodes and it works perfectly. This is what is cusing the bottleneck!! incredible...
    Thanks a lot
