WebI poor performances

Hi all,
I've an issue about performance of WebI reports: refreshing a report (containing only one query on Oracle Universe) takes much more time than running the same query in Toad.
I supposed it was due to the fact WebI has to organize data in tables/charts ...but even if the report I leave the report empty (a blank sheet) its refresh takes a very long time compared to the time requested by the same query in Toad. 
Maybe it takes time to BusinessObjects to save data in the repository: is there any parameter/option I can set up properly to solve this problem? 
Many thanks for your advice

hi,
There are 2 ways you can limit the data in WEBI report if Query returns more data...
1) Universe   (All reports will be impacted )
Universe Parameters -> Controls -> 'Limit size of result set to'
Here you can specify the number of rows a query can return.
2) WEBI    (specific to report)
Edit Query -> Properties -> Limits -> Max rows retrieved
Just set the number low to verify that WEBI could bring atleast fewer records (Partial results).

  • 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

  • Poor performance of web dynpro application

    Hi,
    I have developed web dynpro application which fetches data from R3 system using JCO connection.Large amount of data is transferred between R3 and application,because of which it is taking too long for displaying result.
    After displaying timestamp before and after RFC execution code I came to know that, it is taking approx. 5 min for RFC execution, resulting in poor performance.Time taken for rest of processing is negligible.Is there any way by which I can reduce time for RFC execution or data transfer?
    Thanks in advance,
    Apurva

    HI Apurva,
    I think u r displaying the whole data at a stretch in the front end. So it will take some time for rendring. So try to reduce the display elements (For example, for tables, display only 10 rows at a time).
    regards

  • General poor performance of my Mac mini

    I have been using my mac mini for over a year, it continues to frustrate me how slow and unresponsive it can be even though I do very little with it, i.e organise photos and browse the web - usually looking for solutions to the poor performance problem!
    I came a cross this app that has given me lots of information, unfortunately with my limited IT know-how there is nothing here that gives me any clues, as to the cause of the problem. I guess the red font is not good?
    I'm sorry i can't be more specific about the problem other than to say that iPhoto and Safari the two programmes i use way more often than any other, keep giving me the beach ball. My internet speed is ok 25 Mbps down - 4.5 Mbps
    Is there anything here that stands out as being wrong? if so any suggestions/ instructions for what I should do?
    p.s. i had to quit Safari while writing this and have a report for this if it helps?
    Any help much appreciated.
    Problem description:
    My mac is just generally very slow. I only use it to look at the internet and manage photos.

    Hi Linc Davis
    Thank you for taking the time to respond.
    I got this information from a time when I was opening up iPhoto, and then going to the iCloud folder. To be honest it wasn't the most disastrous of events, I did get a few beachballs and when I opened up a shared folder the photos weren't loaded as normal. As I get more lengthy delays in carrying out any activities I will post back the console results.
    Just as a bit more info, I don't consider my problem an update to Yosemite problem, if anything since updating performance has been improved from Mavericks.
    Do you have any comments about upgrading RAM from the 4GB I have?
    Should I act on any of the messages in red from the EtreCheck report?
    Many Thanks
    Duncan

  • 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.

  • 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?

  • Poor performance on reports that were migrated from 6i to 10g

    We are migrating from 6i client server to 10g reports server and getting poor performance on various reports. Reports that work in seconds in 6i are taking much longer to run or even timing out.
    Reports Server:
    Version 10.1.2.0.2
    initEngine = 1
    maxEngine = 20
    minEngine = 1
    engLife = 1
    engLife = 1
    maxIdle = 30
    The reports are being called from 10g forms with the following:
    T_repstr := '../reports/rwservlet?server=rep_aporaapp_frhome1'
    || '&report='|| T_prog_name
    || '&userid='|| T_nds_uid;
    || '&destype=cache'
    || '&paramform=yes'
    || '&mode=Default'
    || '&desformat=pdf'

  • BPS Web Document Performance

    I have layouts that read documents. In BPS0, performance is excellent whether calling up an existing comment, or inputing new ones.
    However on web, it takes forever after clicking on a cell selection for the document to show up.
    I did not find any notes on this topic. Could someone share his/her experience on the issue? Thanks very much.

    Has there been any response to this issue? I am also experiencing performance problems with the usage of documents with web layouts. Activating the document component and retrieving documents is awkward for users - poor performance.
    Any suggestions?

  • BI4 - Poor Performance

    Hi,
    I have a problem updating several reports which either time out or take ages to respond when making simple changes. It doesn't seem to matter which mode you are in while making a change (whether in data or structure mode) nor the tool used (Webi or Rich Client).
    I have read in other forums users reporting similiar problems which results in an error unable to get the first page of the report.
    To ensure it wasn't an issue inherited from a previous version of BO (as these reports were originally written in BOXI BI 3.1) I recreated the report from scratch only to hit the same issue when populating the report with various formula.
    When this occurs (i.e. the unable to get the first page of the report error occurring) I am forced to save then close the Rich Client and then have to re-open the file each and every time.
    We are currently using Business Objects BI4.0 SP6 Edge. These reports consist of some 600+ variables however they never caused this issue in the older version of BO.
    Please can someone suggest a solution to this issue as it is taking me much longer to make simple updates to these reports when it ought to be straight forward.
    Cheers
    Ian

    Hi Farzana,
    Thanks for your response. Yes, I had read this on a variety of forums and due to the poor performance wrote the report from scratch again.
    Firstly, I got the structure of the report and saved it as a template. No issues. Then add in Queries and variables. No issues. It was only when I had populated the report with the formula / calculations (after about my half way point) I started to detect performance issues again.
    This forced my hand and I used RestFUL Web Service calls to complete the rest otherwise it would of been a painful excercise. The report contains some 600+ variables as 750+ cells populated with formula calculations so it is a busy report.
    I would of thought others with complex reports may have reported similiar performance issues as this worked fine in our old BOXI v3.1 environment.

  • Poor Performance with Fairpoint DSL

    I started using Verizon DSL for my internet connection and had no problems. When Fairpoint Communications purchased Verizon (this is in Vermont), they took over the DSL (about May 2009). Since then, I have had very poor performance with all applications as soon as I start a browser. The performance problems occur regardless of the browser - I've tried Firefox (3.5.4), Safari (4.0.3) and Opera (10.0). I've been around and around with Fairpoint for 6 months with no resolution. I have not changed any software or hardware on my Mac during that time, except for updating the browsers and Apple updates to the OS, iTunes, etc. The performance problems continued right through these updates. I've run tests to check my internet speed and get times of 2.76Mbps (download) and 0.58Mbps (upload) which are within the specified limits for the DSL service. My Mac is a 2GHz PowerPC G5 runnning OSX 10.4.11. It has 512MB DDR SDRAM. I use a Westell Model 6100 modem for the DSL provided by Verizon.
    Some of the specific problems I see are:
    1. very long waits of more than a minute after a click on an item in the menu bar
    2. very long waits of more than two minutes after a click on an item on a browser page
    3. frequent pinwheels in response to a click on a menu item/browser page item
    4. frequent pinwheels if I just move the mouse without a click
    5. frequent messages for stopped/unresponsive scripts
    6. videos (like YouTube) stop frequently for no reason; after several minutes, I'll get a little audio but no new video; eventually after several more minutes it will get going again (both video and audio)
    7. response in non-browser applications is also very slow
    8. sometimes will get no response at all to a mouse click
    9. trying to run more than one browser at a time will bring the Mac to its knees
    10. browser pages frequently take several minutes to load
    These are just some of the problems I have.
    These problems all go away and everything runs fine as soon as I stop the browser. If I start the browser, they immediately surface again. I've trying clearing the cache, etc with no improvements.
    What I would like to do is find a way to determine if the problem is in my Mac or with the Fairpoint service. Since I had no problems with Verizon and have made no changes to my Mac, I really suspect the problem lies with Fairpoint. Can anyone help me out? Thanks.

    1) Another thing that you could try it is deleting the preference files for networking. Mac OS will regenerate these files. You would then need to reconfigure your network settings.
    The list of files comes from Mac OS X 10.4.

    http://discussions.apple.com/message.jspa?messageID=10718694#10718694
    2) I think it is time to do a clean install of your system.
    3) It's either the software or an intermittent hardware problem.
    If money isn't an issue, I suggest an external harddrive for re-installing Mac OS.
    You need an external Firewire drive to boot a PowerPC Mac computer.
    I recommend you do a google search on any external harddrive you are looking at.
    I bought a low cost external drive enclosure. When I started having trouble with it, I did a google search and found a lot of complaints about the drive enclosure. I ended up buying a new drive enclosure. On my second go around, I decided to buy a drive enclosure with a good history of working with Macs. The chip set seems to be the key ingredient. The Oxford line of chips seems to be good. I got the Oxford 911.
    The latest the hard drive enclosures support the newer serial ata drives. The drive and closure that I list supports only older parallel ata.
    Has everything interface:
    FireWire 800/400 + USB2, + eSATA 'Quad Interface'
    save a little money interface:
    FireWire 400 + USB 2.0
    This web page lists both external harddrive types. You may need to scroll to the right to see both.
    http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/eSATAFW800_FW400USB
    Here is an external hd enclosure.

    Here is what one contributor recommended:
    http://discussions.apple.com/message.jspa?messageID=10452917#10452917
    Folks in these Mac forums recommend LaCie, OWC or G-Tech.
    Here is a list of recommended drives:

  • Apple maps has received a poor performance rating just after introduction of the iPhone 5. I am running google maps app on the phone. Siri cannot seem to get me to a specific address. Where does the problem lie? Thanks.

    Apple maps has received a poor performance rating just after introduction of the iPhone 5. I am running Google Maps app on the phone. SIRI cannot seem to get me to a specific address. Where does the problem lie? Also can anyone tell me the hierarchy of use between the Apple Maps, SIRI, and Google maps when the app is on the phone? How do you choose one over the other as the default map usage? Or better still how do you suppress SIRI from using the Apple maps app when requesting a "go to"?
    I have placed an address location into the CONTACTS list and when I ask SIRI to "take me there" it found a TOTALLY different location in the metro area with the same street name. I have included the address, the quadrant, (NE) and the ZIP code into the CONTACTS list. As it turns out, no amount of canceling the trip or relocating the address in the CONTACTS list line would prevent SIRI from taking me to this bogus location. FINALLY I typed in Northeast for NE in the CONTACTS list (NE being the accepted method of defining the USPS location quadrant) , canceled the current map route and it finally found the correct address. This problem would normally not demand such a response from me to have it fixed but the address is one of a hospital in the center of town and this hospital HAS a branch location in a similar part of town (NOT the original address SIRI was trying to take me to). This screw up could be dangerous if not catastrophic to someone who was looking for a hospital location fast and did not know of these two similar locations. After all the whole POINT of directions is not just whimsical pasttime or convenience. In a pinch people need to rely on this function. OR, are my expectations set too high? 
    How does the iPhone select between one app or the other (Apple Maps or Gppgle Maps) as it relates to SIRI finding and showing a map route?  
    Why does SIRI return an address that is NOT the correct address nor is the returned location in the requested ZIP code?
    Is there a known bug in the CONTACTS list that demands the USPS quadrant ID be spelled out, as opposed to abreviated, to permit SIRI to do its routing?
    Thanks for any clarification on these matters.

    siri will only use apple maps, this cannot be changed. you could try google voice in the google app.

  • 2004s Web report performance is not good ,though that of 3x web is OK.

    Hi,
    I feel 2004s Web report performance is bad, though that of 3x web is no problem (the same query is used.) it is worse than BEx analyzer.
    This query has more than 1,000 records and those queries that have many records result in the same bad performance.
    Of course there are many reason for this bad performance, please tell me your solution by which you solve the same problem like this.
    the SIDs of EP and BI is difference here.
    CPU is not consumed when 2004s web report is executed.
    And I have cancelled  virus scan to this web report...
    Kind regards,
    Masaaki

    It is bad, am sure it's down to the new .net and java based technology.  Aggregates are a way forwards though from what i've heard of the BI Accelerator this is the real way forwards.

    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.

    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.

  • 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!
