Poor performance accessing PCI-6025E
NI Software : Visual C++ version 6.0
NI Hardware : Multifunction DAQ device PCI-6025E
Driver Version : 6.9.1
OS : Windows 2000
I am having a problem with the speed at which the card is accessed. This only occurs on one computer. Other computers are working fine and the code that we
wrote is the same for all computers. Interestingly, the Test Panel seems to work fine on the computer that isn't running my software right. Also, my software appears to run fine on the slow computer for about 3-5 seconds before it bogs down. Specifically, a call to AI_VRead goes from basically instantaneous response to taking 300-500 milliseconds. The computer with
the problem is something like a 3GHz P4.
Could it be a video (or other) driver issue? IRQ issues can cause hiccups like the one you mentioned.

Poor performance of PCI express storage options
Does anyone know if there's anything lacking in the performance of disk off of PCI express in the mac pro?
e.g. I get better performance straight from a SATA connection with the same disk than I do via eSata via PCI express.
RAID 0 a couple disks off of PCI express and it is also no better than one of the disks connected via SATA.
I thought PCI express would have higher throughput; actually it does on other systems.
Anyone with a PCI express board that actually delivers better performance?Hi,
If you desire great RAID performance with a Mac Pro PCIe controller, I would suggest the FirmTek SeriTek/2ME4-E. You can view its RAID performance with up to four OWC SSD's here:
http://www.firmtek.com/seritek/seritek-2me4-e/perform/
With dual SeriTek/2ME4-E controllers, the four drive RAID provided 850MB/s Write and 995MB/s Read.
Hope that helps,

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. -
Poor performance and high number of gets on seemingly simple insert/select

exe #2 : elapsed = 6.34s, query = 24272, current = 151, rows = 25
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 :
call count cpu elapsed disk query current rows

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 :
call count cpu elapsed disk query current rows
Parse 1 0.00 0.00 0 0 0 0

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.
thanks and regards
Ivanhi 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).

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? -
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.
AntonOn 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)?

Installed PCI-6025E recognized by Windows XP but only in PXI system by MAX
I installed a PCI-6025E DAQ board on a Windows XP machine. Upon startup it recognized the new hardware and installed the driver from the NI-DAQ 6.9.3 CD. All seemed to work fine. When I try to bring up the device in MAX it only shows up in the PXI system section. This doesn't assign a device number or allow a test panel. So I don't know how to access the signal from Labview programs. Is there something I haven't done right?
Hello magicjoecuda,
In general it sounds like you have done everything right and it is not that surprising that the 6025E shows up as a PXI device, but it is unexpected that it does nost appear as a DAQ device. I would try 2 things to work around this:
1) Try installing the card in a different PCI slot on the computer.
2) Uninstall the 6.9.3 driver and try installing the newest version of the driver. A link to the newest version of the driver for your board can be found here:

Take care,

Hello all,
I recently upgraded from a Linksys Wireless-N router that was only a few years old to the EA6500. Since upgraded I have constantly been have performance and range issues with the new router. On many of my devices the WiFi drops constantly and the only way to stop it is to reset the router. With range I am only getting around 20 feet before I start having connection issues. With my old wireless-N router I was receiving around double that. I even have problems with devices such as my Google TV being able to located my PC for streaming content unless I manual connect using the IP address. Wired connections work without any issues.
I have changed the channels and the spectrum so nothing is changing automatically. At this point I am at a loss of what to do. Is it just that this router has poor performance? I would be surprised since this was fairly expensive.
Any help or tips would be appreciated.I dont know with your old N router, but the EA500 is a dual band. Try changing the wireless name of the 5ghz so that it is different from the 2.4 ghz. This prevents the dual band wireless computers or devices from switching between the 5 and 2.4 ghz causing wifi drops.
Check if your router's firmware is up to date. You can click on connectivity and click on check for updates. If there's a new firmware available, better update it.
Set your wireless security to WPA2 personal, on both the 2.4 and 5 ghz band.
Bring the router as far away as possible from any wireless device that could cause interference, even electronic devices.
Place your router in an open elevated place to eliminate wireless signal obstruction.
If your have access points or extenders in the network, make sure that the devices are in sync with the settings of your new router.
Make sure you are using the recommended power adapter of the new router and not the power adapter of your old N router (this happened to my friend before). -
Poor performance of VL10A transaction
Hello Experts,
We are facing very poor performance in One of our production system in VL10A transaction
I checked for the response time and it is going up to 5 seconds
I checked for :
Table Space > it is fine
Pending updates ? it is fine
Available workprocesses > it is fine
Abap Dumps > no major issues.
Could any body suggest ??
Thank you
Regards,
Amber SHi
Try to get a working example of the transaction with poor performance. I would just run the transaction and monitor the work processes SM50 at same time. If you always see your request on a certain table, for example VEPVG, then I would take an SQL trace with transaction ST05.
If the process in SM50 is only on a table (-> accessing the database) for a short time, then you would investigate more on the Abap side.
Btw, if you did not modifiy anything, then you can always go to SAP support (-> look for SAP notes first!) as this is a standard functionality.
Best regards, Michael -
Poor Performance with Converged Fabrics
Hi Guys,
I'm having some serious performance issues with Converged Fabrics in my Windows Server 2012 R2 lab. I'm planning on creating a Hyper-V cluster with 3 nodes. I've built the first node, building and installing/configuring OS and Hyper-V pretty straight forward.
My issue is with Converged Fabrics, I'm absolutely getting very slow performance in the sense of managing the OS, Remote Desktop connections taking very long and eventually times out. Server unable to find a writable domain controller due to slow performance.
If I remove the converged fabric everything is awesome, works as expected. Please note that the cluster hasn't even been built yet and experiencing this poor performance.
Here is my server configuration:
OS: Windows Server 2012 R2
RAM: 64GB
Processor: Intel I7 Gen 3
NICS: 2 X Intel I350-T2 Adapters, supporting SRIOV/VMQ
Updates: All the latest updates applied
Storage:
Windows Server 2012 R2 Storage Spaces
Synology DS1813+
Updates: All the latest updates applied
Below is the script I've written to automate the entire process.
# Script: Configure Hyper-V
# Version: 1.0.2
# Description: Configures the Hyper-V Virtual Switch and

I would really like to know why I'm getting absolutely poor performance. Any help on this would be most appreciated.I didn't parse the entire script, but a few things stand out.
SR-IOV and teaming don't mix. The purpose of SR-IOV is to go straight from the virtual machine into the physical adapter and back, completely bypassing the entire Hyper-V virtual switch and everything that goes with it. Team or SR-IOV.
You're adding DNS servers to adapters that don't need them. Inbound traffic is going to be confused, to say the least. The only adapter that should have DNS addresses is the management adapter. For all others, you should run Set-DnsClient -RegisterThisConnectionsAddress
$false.
I don't know that I'm reading your script correctly, but it appears you have multiple adapters set up for management. That won't end well.
It also looks like you have QoS weights that total over 100. That also won't end well.
I don't know that these explain poor performance like you're describing, though. It could just be that you're a victim of network adapters/drivers that have poor support for VMQ. Bad VMQ is worse than no VMQ. But, VMQ+teaming+SR-IOV sounds like recipe for
heartache to me, so I'd start with that.

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.

Poor performance on admin console after adding 1k+ teams and member profile
We run v7sp3p2 (MS) now but even back on v5.1 see degraded performance in form of response times over 60 seconds when browsing security hierarchy in admin console after adding over 1000 teams and member access profiles. We need the granularity in access for our many users. Does anyone know any tricks to prevent the glacial and disappointing response times while maintaining the necessary security? This behavior reflects poorly on the product's scalability.
Thanks,
ErikSorin, I want to make sure I understand your recommendation.
First, we do have more than 1000 users. Each location has a unique team to which their users belong, and each of these teams has a member access profile with corresponding read/write access to the dimension member representing their location. The users at each location only view data for their own location.
Is your recommendation to use another interface besides the admin console for accomplishing security updates?
We have a custom package that uses an API to upload data files with mass updates to security assignments and definitions, but hesitate to use this method for mundane changes for add/remove/change just a few users as this method bypasses the domain validation we get on the front end wherein we can only add users to the domain they correctly belong to.
To dodge the risk of a bad user/domain matchup we'd like to use front end but it appears to not support our scale well.
Thoughts on a setting or configuration we could manipulate to resolve the poor performance would be great - what levers can we pull? If this is all the tool can support we just live with it and pay the cost in wasted man hours over the life of the product... -
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.

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.

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

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.
