Trash and System Performance

Need to know for company SOP reasons whether or not keeping thousands of files in the trash for weeks affects mac performance in any way. I always remember from OS 7 and up that you wanted to keep the trash relatively clean for best finder performance. I remember also having issues running maintenance on mac's with a large number of trash files that were not yet deleted. Are there any links that you can provide on the this subject. Thanks in advance.

Unless the hard drive is almost full, the amount of files stored on it, whether they are in the trash or not, does not affect performance.

Article Listing and system performance

While creating physical inventory document, we experienced running each site for 25 to 30 minutes. With over 140 sites, it will take approximately 3 days just to create the PID's. We had consultants looking into our system and suggested that we could delist to improve the PI process and overall system performance. Through initial testing of delisting (WSP6), it did not help the PI processing time(creating PID's through MI31). So, I thought that we should archive site data only, but not at Client level, meaning delete all site extensions. Can somebody tell me (a) if this is the right approach?, (b) what are the things to watch out for? (c) can I list the article again if later we find a need for it?
Looking forward to some help. Thanks.

Classification data organization and system performance

We are planning on setting up classification for the material master. Reviewing discussions on the topic indicate the potential for system performance issues with search response and file sizes. Performance is dependent on several factors such as the number of material numbers, classes and characteristics, use of interval values, depth of hierarchies ect.
We have a significant number of material numbers, looking to have at least 15 classes with about 200 total characteristics. The extent of superior class linkage is undetermined at this time.
I am looking for a guideline or tool that would help us understand if our design is efficient or will lead to long term performance issues. Is there a resource or documentation that gives some examples of situatinos where classification got our of hand and why?
Thank you
Brian

Hello Brian,
There is no document or guidlines as such however you should keep the tables upto date . Also we recommend to use CLST for updating statistics regularly. Are you looking to assign 15 classes for material ? It should not affect the performance as much but you should keep characteristics to minimal in that case. Also are you using VC as there are lot of recommendations for VC but in general for classification keeping the stats upto date is most important.
Thanks

HD and System Performance Question

Hello,
I've a standard 160 Go 8 Mo cache HD (from origin) in bay 1 with the OS X System, and 2 other 300 Go 16 Mo Maxtor HD in bay 2 and bay 3.
First, I'd kike to know if it makes a real difference if using a 16 Mo cache HD instead of a 8 Mo for the OS X performance.
Then, if I decide to migrate the OS X in the HD in bay 2 or 3, is there any influence on performances or does OS X have to be installed in HD in bay 1 only ?
Thanks for your help and support.
Lionel.

I use to think that a 16MB cache made a lot of difference. However, based on testing I found that the difference is usually minor. As an example see how little difference the Seagate 16MB provides in this AMUG review:
http://www.amug.org/amug-web/html/amug/reviews/articles/seagate16/
The real performance factor is how fast the hard drive is not how big the cache is. A medium speed drive will not become fast by slapping a 16MB cache on it. The Maxtor Maxline III's all have 16MB and they perform very well. However, placing a 16MB cache on a Seagate 7200.8 or 7200.9 does not increase the speed of the hard drive significantly.
Talk to any sales person and they will always tell you that you will notice a difference in performance between the same drive with a 8MB vs 16MB cache. I found this generic response not to be true.
While a fast hard drive usually has a 16MB cache. The 16MB cache in and of its self did not make the hard drive fast.

Possible solution to wireless/bluetooth/and system performance issues.

I had a TON of issues with Leopard after my Tiger Install, network, bluetooth, video playback, iTunes playback, system performance and freezing just to name a few. I tried everything (reseting PRAM, etc.) to fix the problem and have done a variety if installations half a dozen times. Yesterday I took out my 3rd party memory I had installed (Corsair if anyone cares) and did an erase and install. I've had no problems so far and everything seems to be running great. I'll keep everyone posted on any progress. You may want to try this if you think you may have the same issue.

Hi
I may have the solution to slow performance when using multi core processing. I was testing out realflow 2013 and noticed simulations were talking a long time to finish when using maximum threads 32. I set the threads to 8 and the simumlation was twice as fast which did not make any sense to me. The simulation was taking 1min 24 secs to finish using 32 threads and 45sec using 8 threads. I realized their has to be a problem here. So I went into my BIOS and disabled Hyper Threading. So now instead of having 32 threads I only have 16 threads. When i went back to try the same simulation again this time the 16 threads was only taking 24secs to finish. and the 8 threads was taking 35secs to finish. This made a lot more sence to me.
Anyway so once I realized that turning off Hyper Threading fixed my simulation problem maybe it might be the cause of my slow performance in AE using multi processing. I tried AE and now multi processing is working great very fast now and stable. MP renders start right away now instead of getting stuck on frame 2 or saying initializing background processes and never ever doing anything. Before I had to keep disabling MP and re-enabling it in AE to get it to start working again and still it wasen't very stable
If anybody is having issues with slow performance from their Multi processor systems try disabling Hyper Threading in the BIOS it might just fix your problem.
Hope this helps

Hard drive noise and system performance.

Just like normal, my hard-drive makes noises (normal clicking, etc). When I'm doing something though, like typing, the system slows down for just a split second once a noise it made, stops registering my letters and then types all the letters that weren't regestered. (Keep in mind, this is over a one second period).
For another example, when I launch dashboard, the widgets will start to appear on screen, stop for a (not even a) second, then the widgets will fall into place like they should. I have run disk utility multiple times, and each time it says that the HD is fine.
Is this behavior normal? I can live with it, it's just kind of annoying.

lol, I was going to add "as long as it's not doing that all the time" ...but was hoping for the quick fix. You might want to check your Activity Monitor and see which program or background process is causing the activity ...have you installed anything lately that coincided with this problem? You also might want to try booting into Safe Mode to see if things still persist.

Publish HTML to xMII 12.0 and system performance is poor

Hi all,
I'm having an issue since we upgraded to 12.0.   When I publish my page to MII, the whole system slows down. This lasts forever. ( 2 - 3 minutes) And then the HTML pages return to normal processing speed.
As I develop, I publish many times in one day or even an hour.   Has anyone else experienced this? Is there a way to "fix" it? Any settings/changes?
Thank you,
Michelle

Well - maybe publishing a lot not the right thing to do.
It's my development system.   The way I program is by pieces.   I do the first change. Publish.   Test to see if there are any errors. If there are errors, I correct and then publish again.
Next - I add the next part of requirements and then publish again.
I will publish a lot if I'm having trouble with a piece of code.
I don't know of anyway to test my HTML page prior to publishing.

How do I block an ad that opens up a new Firefox window and keeps telling me my system performance is poor? I can't even capture the link.

This particular ad, supposedly from a Windows Certified Partner, opens in a second Firefox window and keeps flashing the message that my System Performance is Poor, wanting me to click on their ad and let them do whatever nasty things they want to my system. I have not been able to capture the path but next time it comes up, I will write down all that I can see.
If I have closed my main Firefox screen first, and then close out this ad, the next time I open Firefox, the ad opens and all my standard tabs are gone, requiring me to reopen each one seperately (Facebook, Google, etc).

Just to address the last point: check your History menu to see whether you have the Restore Previous Session option and use that if you can. If that is grayed out or doesn't restore everything, check the Recently Closed Windows and Recently Closed Tabs lists for other pages.
The unwanted window may be generated by an add-on. Try disabling ALL nonessential or unrecognized extensions on the Add-ons page. Either:
* Ctrl+Shift+a
* "3-bar" menu button (or Tools menu) > Add-ons
In the left column, click Extensions. Then, if in doubt, disable.
Usually a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.
Any improvement?
Here are some other things to check:
(1) user.js file that changes Firefox startup behavior and overrides your preferences. This article describes how to track that down and delete it if you have one: [[How to fix preferences that won't save]].
(2) Possible hijacked shortcut. Check the "target" of the desktop icon you use to start Firefox to see whether it lists the unwanted page. To do that:
right-click the icon > Properties > Shortcut tab
For 64-bit Windows 7, the Target should be no more and no less than this:
"C:\Program Files (x86)\Mozilla Firefox\firefox.exe"
(3) Possible undisclosed bundle items. If you have installed any free software recently, check your Windows Control Panel, Uninstall a program for surprises. If you click the "Installed on" column head to group by date, it is easier to spot bundled junk. Remove everything suspicious or unrecognized.
(4) Supplemental clean up scans. Our support article lists tools other Firefox users have found helpful: [[Troubleshoot Firefox issues caused by malware]].
Hopefully that cures it.

Process Order tables and Production System Performance

Hi All,
What are the different tables of Process order? Also how do i know which table affects the system performance of Production system and to what extent if Change Logging is made active ?
The issue is in our clients place we would like to set the Change Logging ( Records changes made for any transaction ) for Process orders and we would like to know to which tables change logging should be made active so that Production system performance is not affected.
Please help me regarding this.
Thanks in Advance,
Neetha Avani.

All the changes done in any transaction are saved in CDPOS table.
when there is any report developed based on this table then the performance will be very slow.
Tables used for process orders are
AFKO            Order header data PP orders
AFPO            Order item
AFRU            Order Confirmations
AFRUHR        Order Confirmations for HR
AFRV             Confirmation pool
AFVC             Operation within an order
Hope the above helps.

How Restore Deleted or Missing OS X Components
A few of the basic OS X installed applications can be restored from the Optional Installs installer located in the Optional installs folder on your Installer DVD. However, if what you need is not there then follow the instructions below.
How to Use Pacifist to Restore Deleted or Missing OS X Components
Insert the OS X Installer DVD into the optical drive. Use a simple utility like TinkerTool to toggle invisibility so you can see invisible items. Alternatively, open the Terminal application in your Utilities folder and at the prompt enter the following:
defaults write com.apple.finder AppleShowAllFiles Yes
Press RETURN.
To turn off the display of invisible files repeat the above command substituting No for Yes.
The install packages are located in the /System/Installation/ folder on the DVD.
Download the shareware utility Pacifist. Use it to extract a fresh copy of the missing item(s) from the file archives on your OS X installation DVD. The file archives are in the /System/Installations/ folder (use Go to Folder option in the Go menu of the Finder.)
Here are Four Basic ways to use Pacifist (courtesy of George Orville.)
A. Drag a .pkg icon onto the Pacifist window .....proceed to step 7.
B. Click on “Open Package ....” and navigate to package desired and click “Open” in
the open/save window.....proceed to step 7.
C. Insert Mac OS X installer CD and when it mounts, navigate to .... Menu->Go->Go
to Folder. In the path field enter or paste ....
/Volumes/disc name/System/Installation/Packages (where disc name is the name of the CD/DVD that you inserted.)
Click on the "Go" button ..... • Drag a .pkg to Pacifist..... proceed to step 7.
The package you'll need will have to be discovered by trial and error, but for most applications you should start with the Essentials.pkg and/or Additional Essentials.pkg.
D. Insert your Mac OS X install disk 1 .... and open Pacifist.
1. In Pacifist, select "Open Mac OS X Install Packages" ... dialog may appear asking for disk 2, then disk 3 and finally disk 1 again.... {if DVD is not used)...If “Stop Loading” is selected...the procedure will stop!!!
2a. When loading is complete, a new window appears, click the triangle to display contents of each package...Select item and proceed to step 7.
2b. or click the “Find” icon in the Pacifist window and type the name of the software you need.
3. In the list that comes back, click the top most entry for the item that you want. ..... that is the one for the English language.
4. On the top of the Pacifist window, click “verify” .... you will probably be prompted for your password.
5. Enter checks for.... “verify permissions” and “verify file contents.” and click “verify” ....enter password when prompted.... you will get back output which may look like this:
20 files were scanned. 20 of 20 files were present on the hard disk. 0 of 20 files had file permissions that did not match those specified in the package. 0 of 20 files had checksums that did not match those specified in the package.
6. Click “close”. Go to step 7.
Extract or Install........
7. In the Toolbar (upper left), you now have the option to extract or install. Click a file in the lower list and those two icons will be enabled.
8. If “Extract to...” is selected.... navigate to the location where the file will be placed, select “choose”, select “extract” in new dialog that appears,authenicate , if prompted, click “OK”.
9. In the next dialog, click “Extract”.
10. If “Install” is selected... dialog will appear with the location/path of the installed software. Click “Install”
11. Type in your password, click “OK”
Pacifist will begin to extract files.
12. In steps 8/10ß.... you also have the choice to “cancel”
Notes: Pacifist may find that a file it is installing already exists on the hard disk. Pacifist will present you with an alert panel....
• Stop
• Leave original alone
• Update .....
• Default selection
• Replace .... (Replace option should only be used on full install packages)

System Performance window and CPU usage

The System Performance window shows two bars - what do these mean? My guess would be for dual cpu, on my quad only two show up but I assume that's because Apple needs to update to show all four?
Related question - when doing a torture test on my quad, Logic seems to show almost full CPU usage and choke while Activity Monitor only has logic using about 130% of available cpu (out of 400%). Processor load seems to be split equally between all four (none of which seem to be averaging over 50%). On a dual, how close does Logic get to 200%? Is there anything I can do to get Logic to use more of the available CPU power?
I'm running an assortment of softsynths, most with Space Designer (do longer verbs in SD use more CPU?).
Along these same lines, are there any standard Logic benchmarks?

They indicate multiple processors if audio is subdivided. It is most likely Logic hasn't got a CPU meter update-don't the quads simply operate as pairs per core-fuctionally similar to a Dual but when it comes to the processor the duties are split, as opposed to 4 procs it works more like 2 coupled...
Longer IRs require more calculations, they add up really fast, esp. at higher sampling rates-because the IRs convert to the host (session) rate, as opposed to the rate the IR is.

Is there a documented correlation between high CPU/RAM usage and poor system performance?

I realize this subject is not black and white and has quite a bit of depth to it as high usage of either the CPU or RAM does not necessarily mean that a computer is running slowly.
However, is there any documentation, scientific research or academic journal that makes a correlation between poor system performance and the consumption of system resources.
It goes without saying that if you use all your RAM then there won't be any available for additional programs, but can this be substantiated with metrical data?
