Quicktime 7.1.2 causing poor Rosetta performance

Has anyone else noticed considerably poor performance from any PowerPC apps (such as major lag typing in Microsoft Word) and general system slugglishness after installing the Quick 7.1.2 update?
I have.

Not here. Although I am using Office v.X rather than 2004 and neither have I install Mac OS X 10.4.7.

Time Capsule firmware 7.4.2 causes poor AFP performance

I use the TC internal drive to share media files with my Macbook Pro (OS X 10.5.8) and a Windows 7 laptop. I DO NOT use the TC for wireless. Wireless is disabled on the TC and it is connected to a Linksys dual band wireless device via a gigabit ethernet connection. Here is the situation.
TC firmware 7.3.2
Streaming a quicktime movie over wireless-N to the Macbook Pro over AFP works perfect.
Streaming a quicktime movie over wireless-N to the Windows Laptop over SMB works perfect.
TC firmware 7.4.2
Streaming a quicktime movie over wireless-N to the Macbook Pro over AFP is choppy and pauses.
Streaming a quicktime movie over wireless-N to the Windows Laptop over SMB works perfect.
Streaming a quicktime movie over wireless-N to the Macbook Pro over SMB works perfect.
So I've isolated the problem to an AFP issue I believe. Using a protocol analyzer reveals that the AFP packet exchange between the Macbook Pro and the TC goes something like this.
Firmware 7.3.2
1 packet from Macbook Pro
~12 packets from TC (quicktime movie data)
1 packet from Macbook Pro
~12 packets from TC (quicktime movie data)
etc...
Firmware 7.4.2
1 packet from Macbook Pro
2 packets from TC (quicktime movie data)
1 packet from Macbook Pro
2 packets from TC (quicktime movie data)
etc...
There are other AFP anomalies too using firmware 7.4.2. For example, quicklookd will timeout and fail to create thumbnails for media content on the drive resulting in a console error message. This does not happen using firmware 7.3.2.
What I have done...
I have done a hard reset and erased (after archiving :)) the drive contents using firmware 7.3.2.
Then Upgraded to firmware 7.4.2.
Renamed the share, erased the contents again, renamed the TC, removed old keychain entries, etc..
Whatever I do, reverting back to firmware 7.3.2 always fixes the issue.
Any suggestions for firmware 7.4.2 or does it just break AFP.
Thanks!

Fixed my own issue.
After upgrading to firmware 7.4.2, I
Manually mounted the TC disk (finder -> GO -> Connect to Server...)
Server Address: afp://timecapsulename.local (this was the trick)
Set this to auto mount at login (System Preferences -> Accounts -> Login Items -> + -> Devices/YourMac/theTCvolume)
All works now.

How to find cause of db performance problem??

Hi,
I am facing continuous performance issues with our database and for that I want to know how I can get information about the following points:
1- How to find most accessed table(s) or tables with highest hits or top queries is accessing which table(s)?
2- What indication can tell that a particular table need to be rebuilt?
3- When to rebuild indexes? and how to know that an indexed need to be rebuilt?
Your prompt reply is highly appreciated
Thanks,
Younis

Hi,
a good starting point for investigating poor database performance is AWR (if you have a license for that) or statspack (if you don't). If you need help interpreting it, you can refer to J. Lewis's series on statspack reports (also applies to AWR):
http://jonathanlewis.wordpress.com/2011/03/09/statspack-reports/
I have also made a few blog posts on this topic, see http://savvinov.com/tag/awr/
Regarding your other questions -- countrary to popular belief, rebuilding indexes or tables is seldom helpful. More often, performance problems are caused by bad execution plans (side effects of bind peaking, inaccurate statistics, correlated predicates etc.), data design issues, bad coding practices, not using bind variables etc.
Database performance topic is a huge topic and obviously cannot fit into a discussion thread. Christian Antognini's book "Oracle Performance Troubleshooting" can provide you a gentle introduction into performance tuning, provided you already have good familiarity with Oracle architecture.
Or, if you want help with your particular problem, post your AWR report here and briefly describe what your users are unhappy about -- there is a good chance that you get valuable feedback from several renowned experts.
Good luck!
Best regards,
Nikolay

Poor graphics performance.

Hi.
Include your product name and specs such as processor speed, memory, and storage capacity. Please do not include your Serial Number, IMEI, MEID, or other personal information.
Macbook Pro retina (early 2013)
2.7 GHz Intel Core I7
16GB 1600 MHz DDR3
NVIDIA GeForce GT 650M 1024 MB
512 GB SSD
Provide the version numbers of your operating system and relevant applications, for example "iOS 6.0.3" or "iPhoto 9.1.2".
OS X 10.9.3 (13D65)
Describe the problem, and include any details about what seems to cause it.
My rMBP has poor graphical performance compared to other rMBP. I think there might be something wrong inside it. Appstore or Steam games for Mac (Bioshock Inf and Max Payne 3) at lowest graphical settings will give me between 5-10FPS. I think this might be weird for such a well specced computer.
List any troubleshooting steps you've already tried, or temporary fixes you've discovered.
Formatting, bootcamp with Win7, Updating to mavericks, stopping apps, Reset SMC.
Nothing has worked yet. I don't play games often, but since i first started trying a few times last year, i've noticed that it's almost impossible,

You should be getting more FPS. Do you have switched graphic card option on or off in the energy saving section?

Poor graphics performance over time

I've seen an issue ever since upgrading to Lion where after some period of time (haven't nailed down how long, but measured in hours) 3D game performance suffers greatly (60+fps down to 12fps). Rebooting fixes the issue until it sits long enough.
The drop doesn't seem to happen mid-game... only after leaving for a while and returning to the computer. I've run all the usual diagnostics. The iMac does not "sleep" during that time (i have it set to always on). During the performance slow down, all system stats look normal: no spikes in CPU usage, memory usage, etc. All internal temperatures report out normal as well. No other hardware or software changes other than the Lion upgrade. When the FPS slow down is occuring, all system animations also suffer (sliding in Dashboard, Dock magnification, etc). Quit the game and the system animations come back to full speed.
The game I play most often's technical support is worthless (i'm looking at you Blizzard), so I'm hoping someone else has run in to this issue, or that an actual support person can help without telling me to run a permissions check.
Thanks!

I just bought this MacBook Pro the 26th and it came with Leopard. After installing XP on the system, I can't get over the fact of the poor graphics performance. Even moving windows would result in a bad frame rate. Obviously, this is caused by a lack of "good" drivers for the GeForce 8600M GT. The drivers from Nvidia aren't working, so either this is the best of Windows I'm getting on this system or there's some sort of driver that I haven't heard of. Does anyone have any insight on this?
First off... Congrats on buying a MBP!

Poor Network Performance from VPN sites

We are experiencing poor network performance when connecting from hardware VPN sites. VPN sites have Cisco Hardware VPN client 3002 which terminates to Cisco 3005 VPN concentrator. Geting upload/download speeds of 355/484kbsp from VPN to surewest.com. If I remove the VPN and connect laptop directly to dsl modem, speeds are 3mb up and 1mb down. Any ideas what could be causing this?

Try this
Adjust the MTU and MSS size in concentrator and client.

I have recently upgraded my ipad mini to iOS 6.0.2 and still have poor wifi performance. My 3rd generation ipad works great on the same network. I have done all the resets I can think of but nothing helps. I would not have purchased the mini had I known.

On the same wifi network, third generation ipad, iphone4s and MacBook Pro work just fine. The ipad mini often can not connect with the mail server and seems to hang a long time trying to open a web page. Had I known the mini had this kind of difficulty on wifi, I would have reconsidered my purchase. I have tried resetting the network and renewing the lease on the mini in addition. To completing the most current iOS upgrade. Still poor wifi performance. Unacceptable, in my opinion.

Yes I tried this manyfold. But did not work. Reading on, I took Tesserac's advice. Shut down router and computer.
Start router after 15 minutes and wait another 10 minutes before starting the computer.
Et voila.... everything is back in working order,

[SOLVED] Poor 2D performance of Radeon 7200 with newest xf86-video-ati

Today arrived new version (6.12.99) of ATI OSS driver (also new version of ati-dri 7.6, mesa 7.6 and xorg-server 1.7.1) Since that moment I'm experiencing poor 2D performance, especially in GIMP (scrooling of zoomed canvas). Also switching of virt. desktop where is bloated Java app. or fat Firefox instance result in poor render of screen (program renders by parts/semiwindows).

BTW I'm not using Compiz. Has anyone an idea what could happen? In Glxgears I'm achieving 1200fps, but working with GIMP is laggy-horror.

OSX Lion QuickTime Internet Plug-In causes high CPU load

I have OSX Lion installed.
Now I have a CPU load between 80 to 130% caused by the Quicktime internet plug-in if I watch my ip-camera with Safari. Also I get no Audio out of my ip-camera anymore. In SnowLeopard everything was fine, Safari CPU load at 30%. What is wrong ? Can anybody help me ? It is an Y-Cam Knight SD and a MacMini core 2 Duo.
Karsten Preussner from GERMANY

I had this same problem and couldn't get it to work at all. I tried to install the 3IVX plugin listed here and it didn't do anything. So I uninstalled it.
Then I thought to try my Macbook Pro and see if it was working on that computer, sure enough it was. I checked the HD/Library/Quicktime folder and it only had 4 items in it, whereas on the Mac Pro (that was not working) had 19 itmes in there. So, I moved all 19 out to a new folder and copied only the ones that were in the MBP. When I opened Safari IT WORKED!!! NO MORE PLUGIN FAILURE.
So, I must have just had too many old things in the quicktime folder that was causing it to fail.
Here is a screenshot of my HD/Library/Quicktime folder contents. The top folder shows the 4 items that should be in there (Perian is optional) and the bottom window in the screenshot shows all the stuff I previously had in there which caused the failure.
So If you are having this plugin failure, try removing all but these essentials from your HD/Library/Quicktime folder. It worked for me!

Poor Bluetooth performance with all aluminum Mac Pro

The all aluminum case for pre-mavericks Mac Pro is the primary reason for poor antenna performance of Bluetooth. Aluminum, being a good conductor, acts as a reflector of EMF forming what is known as a Faraday Cage, essentially trapping emissions within the box. Normally, holes drilled in the case would allow enough EMF to pass through the case but the hole size for transmission is directly proportional to the lowest frequency that will pass through easily. An example is the typical microwave oven where the window is actually a conducting sheet with small enough hole such that higher freq light waves pass easily through the sheet but lower frequency microwaves do not. Perhaps if the drive bay covers were made of plastic, transmission of the Bluetooth and wifi would be sufficient. One might carefully nibble a slot or two in the side door but this would surely invalidate any warranty and care would have to be taken not to get aluminum particles inside the computer. This would probably nullify any FCC approval of the machine due to clocking noise interference with other devices. The best approach would probably be a tuned waveguide that passes frequencies only around 2.4 GHz ~ 5 GHz through the case (very similar to the way tuned ports on audio speakers pass a band of frequencies needed to extend bass response). I'm sure Apple will have corrected this design flaw in the new Mac Pro introduced this year. If you have lots of time on your hands you can get a college level text on electromagnetics (Maxwell's Equations, etc.) and derive all the details but with a bit of experimenting and reading about tin can antenna mods to wireless routers you should be able to improve Bluetooth performance significantly.

Thanks for the suggestion. I will have to move my wireless home base station. It is on the same desk as my mini so much less than 5 feet away.

Poor 3G performance from Hutchinson 3 Service Provide at HK

any Hong Kong 3G iphone users experiencing poor 3G performance on Hutchinson 3 network? test my 3G iphone against original EDGE iphone at same spot on office floor, browsing to www.yahoo.com and the performance was marginally quicker than EDGE. after calling our service provide, being told that we were capped on network bandwidth of 7.2mbps but the real speed testing was around 0.3mbps.... this is unacceptable performance.
Apple - please speak to vendor, this is making your product look BAD.

IPhone 4S Poor Battery Performance SOLVED!!

iPhone 4S Poor Battery Performance SOLVED!!
I found the issue with the iPhone 4S battery performance.
I bought 2 iPhone 4S models on the first day. One for my wife and one for me. The strange thing was that mine would kill the battery in 4-6 hours and ran VERY WARM to the touch. My wife's phone worked great. It was cold to the touch. She would forget to charge it at night... and the battery performance was great... even better than our prior 3GS models.
What was the difference? I have my phone connected to Exchange for my corporate email. But exchange is not exactly the problem. The issue is in Notification Center. For some reason, I had hundreds of calendar reminders that kept refreshing on notification center. Furthermore, the reminders would flicker between the time remaining and the start time for the event at such a fast rate that it could not be read... (clearly a bug)
What is the solution? Go to Settings>Notifications>Calendar and disable Notification Center. You can still have the "alert style" set to Banners, or Alerts and you will still receive notices about your events, but it will not BUILD a summary in the Notification Center drop down screen. This is where the BUG exists. [Oddly, this does not affect my iPad 2, but is an issue for iOS 5 on the iPhone (different builds, maybe?)]
So, it appears that Notification Center has an endless loop in collecting the calendar events from Exchange and this is burning up our 4S batteries. Once you stop the madness from Notification Center, your iPhone 4S will perform as advertised.
Enjoy!

POF - Poor Multithreaded performance

I'm chasing down a performance problem that we are encountering during times of high cache puts for POF caches. In a controlled test configuration I am seeing that performance does not scale linearly with 1 thread per physical core. My POF serializer is performing some data compression so it takes a non-trivial amount of time.
My test code calls ConfigurablePofContext.serialize() direcly with one context object instance per thread and with each thread having its own buffer. This should eliminate the network and cache server component of the equation. Further, I replaced the data compression code with some simple CPU only routines to eliminate any exclusive access code that might be in the compression code that would prevent parallel execution. So, as far as I can tell, there should be no dependencies that should block fully parallel execution.
My results on a four core machine are:
threads : executions / second
1     3352
2     6347
3     7640
4     7499
5     5966
6     7441
7     6996
8     7262
It's clear from these results that something is forcing at most two execution at a time. I've simplified my code down to the point that the above serialize() call is the only thing I can think of that would be responsible. If I replace the serialize call with something CPU intensive I will see that 2 threads double the performance, and three and four threads triple and quadruple the performance. So, I know my test code threading works as expected.
This performance matches the scaling, or lack thereof, we're seeing for complete end-to-end functionality so I believe my test is valid.
Does POF serialization allow for fully concurrent execution? Is there a reason why it shouldn't? Is anything tunable that would help?

Oh, I must disagree. The reason I created the test was to identify the source of the abysmal performance we're seeing when we switch from java serialization to POF serialization for just one cache.
We are running Sun Niagara processors which can run 32 native threads simultaneously (4 cores, 8 threads per core). We run 32+ threads on these boxes. So there's plenty of opportunity for lock contention. This cache is written to at ~250/s nominal (~1000+/s peak) on each box. If we run java serialization we can hit those numbers, but with POF we top out at ~60/s.
The only way we have found to get around this is to launch multiple jvm processes on each server. But for peak throughput we have to run 16 jvms per server. That's not manageable.
If this bug really is as minor as you say, what else could be causing such abysmal performance?

Does transferring data from prior phone 3G to new phone i5 cause poor battery life?

Does transferring data from prior phone 3G to new phone i5 as a part of phone activation cause poor battery life?

No

Satellite Pro S500-11C - poor audio performance

Hi Folks,
I have a Satellite Pro S500-11C which suffers from the poor audio performance mentioned in reviews of the S500-11C (yeah I should have *+listened+* to the reviews and excuse the pun).
This is making it very difficult to use this laptop for audio applications such as music, VOIP and Skype without having to carry about a heaeset of some type.
Has anyone else eperianced this problem and had a solution. Any help from Toshiba??
Best Regards,
Andrew

Sorry but what kind of problem do you mean exactly? Is the sound not loud enough or what?
I mean this notebook has standard stereo speakers and not high end harman/kardon speakers inside.
I have Satellite L300 in front of me with same stereo speakers. Sound is OK but not so good as on other laptops with h/K speakers.
By the way: what kind of help do you expect? Some new driver that makes speakers louder maybe?
