Stuttered performance

Hi. I just got a new Mac Pro 2.66 with a gig of ram, and I've noticed that a lot of applications seem to stutter (just take their time, or the mouse pointer turns into the revolving rainbow ball for a while) a lot. Offending applications include Final Cut Pro (5.1.1), Comic Life (1.2.6), and Photoshop CS2 (running in Rosetta, obviously). What's going on? Do I need more RAM? Do I need to change some settings?

It turns out I had to turn off the option to "turn
off hard drives when possible" and this made
performance jump a lot. I will go with the advice of
getting some more RAM as well. Thanks to everyone
for their comments!
I was just thinking about the "Put the hard disk(s) to sleep when possible" option (under Energy Saver) as a possibility as well. I turned that off and my system also seems more responsive. And - fingers crossed - I'm hoping it stops the "black screen" problem I posted about under the Display category.
I also got Boot Camp working

Stuttered scrolling and size changing

If I use the thumbnail size slide bar at the bottom right corner of iPhoto to change the view of either events or faces or photos within albums it is incredibly slow and stuttered, to the point of it taking several attempts to grab and slide the bar. Often the pinwheel/beachball will appear for a few seconds.
I've checked my activity log and my processor rises to 50%-75% during these attempts, but it does not appear maxed out such as when I'm video editing.
Also, just scrolling through events thumbnails is a bit stuttered until I've scrolled the full set (ie pulled them all into memory) and then its smooth.
Why is this? I have plenty of memory (3GB) most of which is currently free, a pretty quick processor 2.8ghz intel dual-co, and all the photos on my internal drive.
Is there a way I can increase the caching size that iPhoto can use?
I get really frustrated with slow/stuttered performance but maybe I'm just being to intolerant? I've posted a similar thread on iTunes which I am finding the same problem. I feel like I've got a pretty high end machine so this should all be silky smooth?
Any tips or help gratefully received.
Thanks,
Dan.

Rebuild the library as follows: launch iPhoto with the Command+Option keys depressed and follow the instructions to rebuild the library. Select the last option.
Click to view full size
That can make a significant different in the load speed of iPhoto. You may have to redo it from time to time depending on how much work you do in Faces and Places.

Pages Entry So Very Slow

Dear Forum,
Does anybody have any idea why pages (4.0.3) keeps stalling. It is as though after every few words I type, the software needs to think about what it is doing so pauses for a few seconds then resumes. As I am a heads down non-touch type typer, I am thinking about creating the text not thinking I need to pause to let the software “do it’s thing”. The frustration from this stuttered performance is positively excruciating.
All other applications have been quit, the documents I type are fairly short possibly but not beyond 2000/2500 words, there are no graphics in the document. But, entry into Pages is now not viable, simply for the sake of my sanity.
I have switched to an open source alternative, but I like, am familiar and quite simply have always used Pages, so would should I have to switch?
Any help may well save the few follicles I have left on my bonce.

Dear Jerrold & Peter,
Many thanks for your quick replies.
It has to be said that I may being going a bit potty as after reading your replies then logging back into the account that is causing me the problems Pages appears to be running perfectly well. Yet for the last week or so I have had this recurring difficulty.
Anyway I opened up Font Book and validated all the fonts which gave passes to each, but having never even launched this software before it goes into my toolbox for future solutions, so thanks for that. Also the direction to keep Activity Monitor open is an excellent way to see what is going on, even if my little Gremlin has taken some time off from causing his mischief. Again cheers.
As to your other pointers: Lots of HDD space around 50%, no effects or text boxes other than the Inpector. Safari not running (but I see your point).
As for how do I use the system, a number of accounts (mainly non-admin) to divide various aspects of my computing up (only one at a time is open). The particular account I use Pages in is word processor specific some browser use (Firefox 3.6), emails and only vary rarely will I invoke GraphicConvertor.
I’ll see how it goes and if this reoccurs then I drop another note, but for the moment, not knowing what I have done to rectify this, I remain stumped, but grateful it has gone away.
Thanks again.

WRT120N - repeated loss of connection requiring reboot

I have an old WRT54GL that has been really good over the years but it was becoming problematic and I decided it was time to get an N router. After a visit to the local PC shop I picked up the WRT120N and brought it home then proceeded to set it up. I got that done and I was using it set to G only as I have an older laptop that can't use N and the router only comes with 1x USB adapter.
After a few days I noticed the internet side of the connection would randomly drop out but I could still access the router wirelessly. Rebooting the router resolved it but it keeps happening regardless of if I use G or N. The confusing thing in this is that it works fine for a while and one laptop works all the time. If it wasn't for the fact that a reboot solves the problem temporarily I would consider the laptop's wireless chip at fault so it points to something with the router.
I've updated the firmware to the latest available but it still happens. Rebooting whenever it happens isn't a solution and unless Cisco have some solution I'm going to end up returning it.

I've given it a fair shot I think. After you posted I reset it to factory default then reconfigured it as well as removing the USB adapter from the equation. After almost two weeks the router has effectively dropped the connection twice a week, or three times in the past week. Each time the same thing will happen and the only solution is to reboot the router. The router is listed on available wireless connections, I can try to connect to it but it will fail for any device. Wired connections aren't affected but that isn't very helpful.
Wired connections seem to suffer a stuttering performance too where there's no throughput whatsoever for a few minutes but otherwise it works. Wireless performance is acceptable but these repeated instances of the connection dropping out mean that I'm resigned to taking it back for a refund.

Slow performance, Audio Crackling and Stutters

I bought my Qosmio X775 7384 just 2 months ago and from the second I took it out of the box it seemed to underperformed, by which I mean it was about 1/2 as fast as my duel core 6gb RAM gateway desktop. I tried to ignore the issue and continued on with my work on my new laptop, using it mainly for music production. Every once in awhile I would get crackling and stutters, this I also tried to ignore but recently when I was in the middle of a performance it completely stuttered out and crashed the computer altogether, which was very embarrassing.
Since then the crackling and popping seems to happen during every song, either in my software, tunes, youth.... pretty much anything with sound has crackling and popping. My music software freezes and crashes and I am still extremely underwhelmed by its performance.
So far I have called and talked to support 3 times, the last time begging for a refund. They want to take my computer for repairs, IM not quite ready to give it up yet as I need it for performing. So here is what I have done.
I reinstalled every windows driver in my devices, I reinstalled every driver from this website and I have done a out of box restore. Nothing has helped.
I ran latencymon and its telling me that my isc and dpc routines are lasting too long for ndis.sys hdaudbus.sys iastor.sys and i8042prt.sys and its telling me that at least one of my problems seems to be network related and that it looks like it could be battery related as well.
Right now I have stripped all unnecessary programs and upgraded my wifi to the euro version of atheros. I believe I have done everything possible to speed up and make my computer stop popping and stuttering and it continues to do so as well as spike in the red of my latency testers.
Please help!

It sounds like you've done everything you can, especially considering that you did an out-of-box recovery. I'd agree that it's time to send it for servicing (or live with it, I suppose).

Xcode 4.1 buggy and performance stutters

Does anyone else find Xcode 4.1 to be buggy? (random crashes etc)
Also, has anyone noticed that the performance is terrible? Window animations stuttering etc (when you show and hide views)

I have found Xocde to be very good at crashing.
Move the mouse a little = crash.
Edit some text crash = crash.
Just look at it = crash.
It's a good developement environment but it is most certainly not as stable as it should be.

Lots of stuttering and choppy performance using GNOME3

ASUS P5K Premium
Core2Quad Q6600 2.40GHz
ATI Radeon HD3870 using Xorg 1.12.4 and Legacy Catalyst 13.1
Creative SB X-Fi XtremeMusic
Basically, the system stutters everywhere: Although CS:Source has great performance (i'd say close to 60fps) it's plagued with micro stutters every 20 seconds or so (as is every other game) and sometimes the performance gets really choppy for no reason. If I drag a window around, just to test, it will eventually stutter, window animations sometimes stutter too, smooth scrolling in web browsers isn't smooth at all (very choppy), flash videos stutter all the time as well! I've taken a look at the system monitor and the process that usually uses CPU the most is gnome-shell which can go as high as 80% but it's mostly at 40%. I installed XFCE just to check and everything's perfectly fine there. Could anyone help me out with this please?

PT? Portugal?
I'm from Portugal.
It's well known that some ATI graphic option can gravelly mess up its performance (micro stutters, choppy performance).
You can try to enable/disable some options. Better to read this, if you haven't already!

Video performance stutters at startup

Just replaced some cheap home-use switches with an SG200-26 and am now get stuttering at startup for video streaming. works fine after (a long) 5-10 secs or so. Haven't messed with QoS, VLANs or much of anything else yet; everything is pretty much out of the box. What could be going on?
Edit: am on the latest firmware

Dear Jean,
Thank you for reaching the Small Business Support Community.
I'd say the "Egress Filter per Queue" QoS feature is a good start point, Egress shaping is useful for when a destination expects a smooth flow of data as opposed to irregular bursts of data. Please check on the article below for details;
http://sbkb.cisco.com/CiscoSB/Loginr.aspx?login=1&pid=2&app=search&vw=1&articleid=1460
Regular QoS settings may also apply. Please refer to chapter 20 ni the admin guide for that matter;
http://www.cisco.com/en/US/docs/switches/lan/csbss/sf20x_sg20x/administration_guide/78-21139.pdf
Please do not hesitate to reach me back if the problem persists and/or if there is any further assistance I may help you with.
Kind regards,

Dedicated graphics shuts down (?) ... stuttering videos and low framerate graphic performance

Hi,
Since quite some time now I have an issue with my macbook pro that seems to be related to the dedicated graphics card and/or the dynamic switching from integrated to dedicated.
The computer runs fine and then suddenly, while watching a flash video, a high resolution html5 youtube video, or playing the video game hearthstone the frame rate of the video / video game drops dramatically.
The only fix is a reboot of the computer and then it is fine again for some time.
It might be related to the power management as it seems to occur more often when on battery or when the battery is low.
I have gfxCardStatus 2.3 installed and when this happens it still tells me that I am running on the dedicated graphic card.
Is that a known problem and is there a fix to it?
I tried to turn off "automatic graphics switching" in the energy saver settings. But this did not help.
specs:
Macbook Pro 15inch Mid 2010
8GB RAM – 2.66 GHz i7
NVIDIA GeForce GT 330M 512 MB graphics
OS X 10.9.5
Thank You!

The model identifier 6.2 MBP that you have has experienced GPU problems. There was a replacement program, but that has expired.
I suggest that you make an appointment at an Apple store genius bar and have the MBP evaluated for FREE. Mention the GPU issue because there is a special test for it.
If it turns out that the discrete GPU is the problem, then you can download this application which will allow you to disengage the discrete GPU and use only the integrated one. This will compromise graphics performance.

A permanent solution would be a logic board replacement.
Ciao.

Audio is stuttering in iTunes and Finder

This is a long post, sorry, but I want to try and be specific as possible. I am stumped, frustrated and at my wits end... any advice/help would be killer!
So, idk what happened, but as of a few days ago (3 to 4 days) my G5 has been stuttering (for lack of a better description) when playing back audio via iTunes or through the Finder window. The 'stuttering' is multiple pauses throughout a song... like 50+ times, making it choppy and unable to play straight through. It's maddening to say the least.
The weekend before Xmas, some Diet Sprite was accidentally spilled in the front of my machine while I was not home. Apparently the machine made some beeps, 'smelled funny', yellow and red LED lights turned on and the machine was promptly unplugged. When I came home 3-4 days after the spill, all was well with the machine until a few days ago when this audio problem started.
I thought perhaps being that the RAM is up front in the machine that the soda could have corrupted the RAM. I ran the Apple Hardware Test with the DVD install disc that came with the computer and 3 hours later, the RAM (as well as all hardware) passed. Same when I ran Tech Tool Deluxe. When I ran Disc Utility, everything checked out fine too. System Profiler recognizes all the RAM as well.
Some things to take into consideration:
-I can use Adobe CS2 Suite apps perfectly. No performance issues at all.
-I have a 2TB RAID external HD which houses my music that iTunes feeds from. Even if I play audio via the Finder window from music files on my Desktop, it still 'stutters.' So it stutters no matter if the audio file resides on the external HD or internal HD.
-I have NOT tried playing music through my iTunes with music located on my desktop HD. I have about 400+ gb worth of music and being iTunes is as slow as it is, call me lazy, but I don't want to discard my library and reload a few albums to see if the 'stutter' problem doesn't happen.
-Music playback is PERFECT if I stream my iTunes to my PC laptop or any other laptops in the house. No 'stuttering.'
-After I ran the Safari update, this problem arose (to best of my memory)
Specs of the computer are: G5 Dual 2.3ghz + 5gb RAM running 10.4.11 with no available updates to install.
Again, if anyone has any idea or anyway to possibly solve this, I'd be forever grateful. Thanx!

Open up Console in Applications>Utilities, watch it for errors when these stutters occur.
I think you should get Applejack...
http://www.versiontracker.com/dyn/moreinfo/macosx/19596
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 5 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files!
Disconnect the USB cable from any UPS so the system doesn't shut down in the middle of the process.

ITunes Stream Stuttering and Crackling Noises (Temporary Work Around Option

Note: If you don’t take the time from your busy schedule to address these suggestions being provided in this and future upcoming series, then by all mean continue with what you were doing before and continue to experience the frustrations and problems. The series is not meant to be a cure-all for the problems you are having. But the information will go a long way toward correcting and improving a lot of issues that you may be having with your system. Think About It !!!!!!!!!!
I listen to the radio a lot using the iTunes player as well as listen to music that I have transferred to the player. When a problem occurs it aggravates me to no end especially if it is occurring when I am try to relax to my music. At times I am also experiencing the stuttering and crackling issues in the 7.0 update that has been recently released. The following information can be useful in temporarily correcting this problem until Apple comes up with a patch to resolve this issue. If you choose to proceed with implementing this information then you assume any liability that may occur during your attempts at using and applying this information. This information has so far suited any needs that I may or am currently having to date personally.
1)Quick Time Preferences – In the Quick Time Preferences\Audio tab check to make sure that the settings are at the default level. Your platform may reflect a different khz Rate. On my platform my default level will be the following:
Rate: 44.1 khz
Size: 16 bit
Channels: Stereo (L R)
When I listen to my music I like a good quality stereo sound so I have my audio sound routed from my laptop to my CD or Video jacks in the back of my stereo. Stereo System: Pioneer SX 251R Receiver. External Speakers: 2 - 8 ohm Yamaha.
Make sure the Safe Mode box is unchecked. Close the Quick Time player. Now, when you begin experiencing the stutter problem there are two immediate steps that you can try to correct the problem:
1)Stop the stream or the music that you are listening too and restart the service each time that the event occurs, (In my case the events that have been occurring has not been consistent when they do occur. Close monitoring in place on all connection ports. Running Snap In’s deployed: IPSec Monitor/MMC Console– Currently monitoring IKE and IPSec Statistics for any changes. To run this snap in properly the Event Monitor must be in the running state and actively logging events in the Administrative\Event Viewer Folder) I will also be configuring Dr Watson to generate a Stack and Dump file log to the desk top in the event of an unexpected occurrence. or,
2)If that does not correct the problem then try the following: Go to the My Computer folder and open it up. When you have done so, Right click the Local Disk and enter the Properties section. When the Local Disk Properties box comes up, enter the Tools tab, in the Error Checking section, place a check mark in the “Automatically Fix System Errors” and click start\yes. Back out of that and close all running programs including firewall in the tray next to your clock and reboot the system.
Once you have rebooted run the Disk Cleanup utility and the Disk Defragmenter utility. While we are using the Disk Defragmenter lets take an extra step to insure that we defragging the hard drive volumes as much as possible. Click on the analyze button a second time. If there are any entries in the box highlight the first entry and run the Defrag utility a second time.
Tip! If you would get in the habit of running defrag process regularly on a daily basis it will help improve the overall baseline performance of your machine.
Last Step: Open your player and try again.
If you are still experiencing the problem and it hasn’t leveled out to your satisfaction then there are two additional steps that I have personally used or am currently using that may help with your issues. The steps will involve installing a small batch file program and a hot fix patch.
User Profile Hive Cleanup Service– (Batch Program) Open your Browser and type in the following address: www.microsft.com once the page has loaded look for the search bar in the upper right hand corner of the page. In the search bar type in the following: “User Profile Hive Cleanup Service”. Once the search result page comes up click on the first result to bring up the proper download page. Before you can use this batch program you will be required to go through a short validation process before you can download the program. The validation process is to ensure that you are running a genuine windows platform.
Overview
The User Profile Hive Cleanup service helps to ensure user sessions are completely terminated when a user logs off. System processes and applications occasionally maintain connections to registry keys in the user profile after a user logs off. In those cases the user session is prevented from completely ending. This can result in problems when using Roaming User Profiles in a server environment or when using locked profiles as implemented through the Shared Computer Toolkit for Windows XP.
On Windows 2000 you can benefit from this service if the application event log shows event id 1000 where the message text indicates that the profile is not unloading and that the error is "Access is denied". On Windows XP and Windows Server 2003 either event ids 1517 and 1524 indicate the same profile unload problem.
To accomplish this the service monitors for logged off users that still have registry hives loaded. When that happens the service determines which application have handles opened to the hives and releases them. It logs the application name and what registry keys were left open. After this the system finishes unloading the profile.
Once you have downloaded and installed the batch file close all running programs and reboot. Now, ‘This is important”, lets determine if the batch file is properly running after installation. Go to Start\Help and Support. Once the Help and Support Center comes up click on the following link: “Use tools to view your computer information and diagnose problems” under the “Pick a task” section. Once the page has been loaded in the left hand pane click on the “Advanced System Information” link. Once that page has been loaded click on the following link: View detailed system information (Msinfo32.exe).
Once the System Information box is loaded look in the left pane and open the Software Environment Tree and click on the following link: Windows Error Reporting. If the batch program is properly running you should see the following entry: “User profile hive cleanup service version 1.6.30.0 started successfully
&#x00a”. The ending symbols may be different on your platform.
Now, we want to go to another location in your system to verify this entry and that this service is properly working again. Pull up your “Control Panel” and enter the “Administrative Tools” folder. Once there enter the “Event Viewer” folder. Then enter the “Application Folder”. If the service is properly working the following entry will be logged: User profile hive cleanup service version 1.6.30.0 started successfully, Event ID 1001. If for some reason this program is not functioning properly a different error code other then the Event Id 1001 will be generated and logged in this folder. Also if one is generated you will want to verify if it’s a genuine error. To do this you need to go back into the help and support center Advanced System Information link and click on the following link: “View the error log”. If anything goes wrong a corresponding general entry that was logged in the Event Viewer will be logged in this link verifying that a problem had occurred. All of the information in the logs will be useful in your trouble shooting efforts. To date I have not had any measurable conflicts to occur while using this batch program to date. Closing Overview: when this program engages it will target itself at the Kernel System only at shutdown and startup. A corresponding entry will be made in the folders that I have described above stating that the program had started or failed.
System Restore Feature and USB Device’s – Event Viewer\System and Application Folders\Event ID SR 1 (Hot Fix Patch) – I have noticed that some folks are loading and unloading iTunes in attempt to correct problems. Also, I see by the forum board that a lot of folks are having a lot of problems with their iPods. Think about this for a moment, iPods will have their own unique set of drivers to operate from. I am going to attempt to explain an experience that occurred with me last year on this issue. When working with USB Devices it is important to keep your eyes on the Event Viewer folders for the following event id being logged: Event ID SR 1. This is especially true if you are using your System Restore Feature. The main folders that you want to keep your eyes on are the “System\Application” folders.
I have not witnessed any specific Software Applications generating this code in general at this point in time. But when it comes to Software and USB Devices I have personally experienced a situation that did cause a SR 1 entry last year. Example: My wife has Sevier medical problems. When we travel I keep a USB Flash Drive on my key chain with her medical information installed in case of an emergence. The Medic Alert E-Health Key was a new device that came out that had bugs that needed resolved just as with iTunes 7.0. The short of the story is that the flash drive was conflicting with the System Restore Feature, which led to additional problems such as conflicts in the Add/Remove Utility. I could not properly unload the Uninstall .Dll files when trying to uninstall the flash drive itself using the Add/Remove Utility. During a conversation with a Microsoft Support tech I was informed that other unloading issues had also been identified in the Add/Remove Utility. I could be wrong but I think there is a patch available that would help with unloading issues while using the Add/Remove Utility. To keep an eye on any possible loading/unloading issues that I may have while using the Add/Remove Utility, I use the following program to determine if there any issue’s that I need to deal with: (30 Day Trial Program-Fully Functional)
http://www.mikasalonen.com/remove/?remove40
Program Name: Remove 4.0. All of the information you need to know about this program will be summarized in the provided link. If anything: USE IT !!!!
NOTE: This SR 1 patch is only a temporary hot fix. They are suggesting that we wait until the next Windows XP service pack release that contains the hot fix.
Article Id : 888402
Last Review : June 01, 2006
Revision : 1.5
Also keep this in mind. The only time that you want to become concerned about the SR 1 issue is when you notice an increase in the number of SR 1 entries in Event viewer logs. If you are logging two (2) or more events then I would begin investigating the problem. Again, In my case the System Restore Feature was identified as the initial cause of conflict when the conflict first occurred when loading the USB Flash Drivers. So, if you suddenly notice this entry in the Event Viewer then you can pretty much bet that you are experiencing a USB issue that is conflicting with the System Restore Feature. But there is a Hot Fix available to temporarily resolve this issue as I have stated. Go back to the Microsoft link that was provided. When the page loads, in the search bar in the upper right hand corner of the page type in the following KB 888402. Be Advised – if you have to resort to this measure you will have to contact the Microsoft Support Team directly by phone to receive this patch.
When you talk to the tech you will need to provide the following information: A brief description if the Event being generated in the Event Viewer as well as a brief description of the problem that you are having. Once the tech has verified the information he/she will e-mail the hot fix to you in a zip folder if I’m not mistaken.
System and Third Party Drivers
Drivers can be another source of conflict that can have a direct impact on how your system operates. I have already given you an example of this in the System Restore/USB Devices section. They can also cause unexpected stability issues. In addition to that malicious Root Kits and Trojans can download drivers on your hard drive without your knowledge further complicating matters. So, before I close this information out let me show you how we can quickly gather and display a listing of all drivers that are currently installed on you hard drive by using a very simple program. (This program will be a 15-day Trial program).
Program Name: My Drivers 3.11
With this program you will be able filter out all preinstalled drivers that came with the system at the time of purchase, thus exposing the remaining Third Party drivers and as well as the Unknowns. If you know what your doing I would take this time now and disable the drive(s) in question if removal procedures are deemed necessary once you have obtained the driver listing. My overall objective with this program is to immediately determine if there is anything out of the norm with the drivers overall.
A download link is unavailable at this time. The web site appears to be under construction at this time.
As a final step on this issue I suggest keeping an eye on the Device Manager for any sudden “Yellow Warning Symbols” appearing within the Device Manager Tree Structure.
Print this information off and us it as a reference point. Any new helpful hints that I can think of will be posted as soon as I can squeeze the time in.

Performance degradation with 11.0.2 CS5 update

Hi!
Has anyone else run into a problem with performance reduction/degradation in GPU mode after updating to 11.0.2 of Flash Pro CS5? I've been working on breakout style game (unBrix), which I carefully built up to run at very close to 60 fps, and it has been fine - until I updated Flash to 11.0.2 (to get Android publish to work, and fix a few other issues).
I have confirmed that downgrading back to the release version of Flash CS5 fixes the performance stuttering that I have noticed since updating to 11.0.2.
I'd love to know if anyone else has noticed a similar problem - or even better isolated the cause - or if anyone has tried downgrading back to see if there is an improvement (I test this by installing the CS5 trial on a VMWare image if that helps).
Thanks,
Kevin N.

I found the same problem with new update and already wrote about this problem in this forum.
You can find my post here: http://forums.adobe.com/message/3214594#3214594
But I same as you don't have any answers.
Also I tried some benchmark test and found that the FPS result is the same for previous & updated packager.
So, I think the problem is only visually. New packager drops a lot of frames. Looks very slowly (((

Performance problems with Leopard 10.5.1

Hello,
I use an iMac 24 Alu 2,8Ghz and upgraded to Leopard. There are some major performance problems and bugs in the recent version of Leopard:
1. While accessing USB devices, the display speed, windows moving, animations etc. slow down
2. Adobe CS3 Photoshop 10.01 and Flash CS3 are sometimes extremly slow. I tried the recent demo packages from Adobe:
2.1. The Photoshop dialogue "save for web" slows down the system completly, and this problem stays when quitting Photoshop. A restart is neccessary then.
2.2. Flash CS3 movie preview is very slow and stuttering. It's so slow you cannot imagine how the real movie flow will be.
2.3. Recent Flash Player 9,0,115,0 with hardware acceleration enabled doesn't really work with QuartzGL enabled Leopard: The movies slow down a lot. Try www.neave.tv for example.
3. Safari, Mail and other bundled software hang sometimes. You have to force quit them then. It doesn't matter whether QuartzGL is enabled or not. This especially happens to my system if it is online for some hours.
4. A lot of Apple applications doesn't seem to work with 2dextreme enabled. Why this? Apple supporters told me in Leopard there will be a much better 2dextreme support. Also Quartz2dExtreme in OSX 10.4 worked with all applications and i guess it's the same feature like "QuartzGL" in Leopard. So Leopard isn't finished here. It would be nice if Apple could make it's own software QuartzGL compatible.
5. Very often the desktop slows down or lags. This is the main reason I often still witch to Windows XP PC to do work in a faster, less annoying way.
6. Safari crashes randomly sometimes. It is unstable still. Also it crashes more often if you resize/move the window a lot, so I guess it is a graphics extension-related problem.
I hope you people from Apple will fix these annoying points and optimize your new system in the next update release.
Best regards

Thanks for you answer. I repaired in the way as described above. There were some errors, some file index was wrong (don't remember exactly the phrase), now the DU reports the partition was successfully repaired / the volume appears to be ok.
The crashes in Safari are gone, but all other described problems still exist. Adobe CS3 is not really usable for me.
By the way, in iMacSoftwareUpdate 1.3, which was replaced by OSX 10.5.1 update, there is one extension called AppleVADriver.kext that does not exist in the OSX 10.5.1 update. Is it an important extension?

Poor performance - QT Player and Safari

Ok, so I've been ignoring this issue on my computer for the longest time and I think it's time I got to the bottom of it.
I'm using a Quicksilver G4, 733MHz, with 896MB RAM.
Now, previously, prior to upgrading to Tiger, using Panther and QT 6.5 something, Quicktime worked pretty much flawlessly. I was so happy with it. After upgrading to Tiger such a long time ago, I noticed QT 7 wasn't nearly up to par and its performance was very bad.
The real issue here is this: Whenever I watch a streaming movie downloaded from the internet, in Safari, it runs choppy. Choppy as in the framerate stutters considerably, the video will pause while the audio still plays, and it basically renders the video unwatchable. The workaround I've been doing all this time, is: downloading the video onto my desktop and playing it through VLC. (Which it does absolutely flawlessly, mind you.)
Oh but it gets better - when I play these EXACT same video files in Quicktime Player - I get "improved" performance, but it still does the same thing: choppy video playback. Now, when I play these same streaming files in Firefox - they work, smooth as a baby's bottom. Quicktime's streaming plug-in works great. Doesn't make sense...
On top of ALL that: After this problem was already engraved in my head after trying numerous troubleshooting (reinstalling latest versions of Quicktime, clearing caches, making a test user account, A&I, etc....) I eventually upgraded my computer, and put another internal 250GB HD in it. So I was basically starting from scratch - a complete erase and install of the HD.
Lo and behold, Quicktime STILL did it. - same exact problem. So I gave up for a while and have been using VLC ever since. Or Firefox.
So that's my problem guys - any suggestions would be nice, or if you'd like, just tell me to keep using VLC and/or Firefox as workarounds and don't even try to fix it. ¬_¬

I do not use Safari. However, I found this troubleshooting technique in the MacAddict Magazine December 06 issue:
To fix a QT related problem w/Safari, quit Safari & look in the /Library/Internet Plug-Ins folder (this is the Library folder at the root level of your HD, not the one inside your Users/user name folder).
Try removing the VLC Plugin.plugin (if you have it) & QT Plugin.plugin files from this folder, & then relaunch Safari. If the problem isn’t fixed, a different plug-in may be to blame. Keep removing files from this folder (start with any third-party plug-ins that are present) until the problem disappears.
Replace the plug-ins that don’t cause any problems.

How do I make my old user account perform like the new one?

I have a macbook pro 13" 2008 with 8 gb of ram that has been showing stuttering in hd video lately (or maybe when i upgraded to lion). I created another user and it doesn't seem to suffer any stuttering. Perhaps it doesn't have weird things running the background like the 655mb kernal task I see in activity monitor. My question is, how do I make my old user account perform like the new one? I've tried to turn off things running the background, but it doesn't seem to do anything. Thanks!
