There may be other software that is causing your problem, but the Blackberry software regularly crops up as being the cause of slow-downs or unpredictable behaviour. Try uninstalling it using the uninstaller that is hopefully available from Blackberry.
Hopefully others will spot this thread and have some other suggestions. There are a few entries for things I've never heard of (not that that means much ), but there's a chance that they are not compatible with Mavericks and could be contributing to the sluggish performance.

Extremely slow performance with Radeon HD 7870

Hi,
I am using a number of Adobe programs on my new Windows 8 64 bit system, with 16 gigs of ram, an Intel Core i5 2.67ghz, and AMD Radeon HD 7870 2 gig. All the programs (including After Effects and Illustrator) work very well with the exception of Photoshop CS6 64 bit, which has extremely slow performance with Use Graphics Processor enabled in my preferences (which Photoshop selects by default). If I turn off Use Graphics Processor, the slow performance vanishes. If I change Drawing Mode to Basic, there might be a slightly detectable improvement over Normal and Advanced, but it's still horribly slow. The refresh rate seems to be just a few frames per second. Everything is slow: brushes, zooming, panning, everything.
I've tried changing the settings I've seen suggested elsewhere: I switched Cache levels to 2, history states to 10, and tile size to 128k. No effect. Photoshop is currently at the default of using 60% of available ram. Efficiency has remained at 100% throughout all my tests. Also, this slow performance has affected me from the moment I installed Photoshop; it didn't crop up after previous good performance. The problem exists regardless of the size or number of documents I have open. Performance is still terrible even when I create a 500 x 500 pixel blank new canvas and try a simple task like drawing with the brush.
Photoshop is fully up to date, and so are my graphics drivers (Catalyst version 13.1). Any help would be greatly appreciated; at the moment performance is so bad in Photoshop that it's unusable with graphics acceleration enabled. Thanks in advance for replying.

Great news!
I followed your suggestion, Noel, and uninstalled my drivers with the Catalyst Uninstall Utility (which I hadn't used before), rebooted, reinstalled Catalyst 13.2 Beta 7, rebooted, deleted the PS Prefs, started PS, and now the performance is radically improved!
It baffles me why I would need to do a clean driver uninstall in a new system environment that has only ever had this video card, and is only a few months old, but that action seems to be what's improved the situation. Note that because I deleted the PS preferences, the good performance now occurs with the default Use Graphics Processor enabled, and Drawing Mode set to Advanced (with every feature in the Advanced dialog checked except 30bit display).
Having no reference point, I can't tell for sure if performance is as good as it theoretically ought to be for my system specs, but using the standard 13px brush is only slightly laggy behind the cursor, even if I become reckless and squiggle on the canvas violently. It wasn't just sluggish response before: Photoshop seemed to be in pain trying to draw the line segments as it laboured to catch up to the cursor. That is pretty much gone now.
Much more tellingly, zooming and panning the canvas is like it ought to be, responsive and clean, more or less like it was for me in CS4 with my old Nvidia 9600GT. The poor performance with zooming and panning was the most worrying aspect of the issue. It's a great relief to see these working more properly now.
I have to confess I'm a little embarrassed to have drug you through all this hassle only to discover that something as rudimentary as properly cleaning out the drivers would be the apparent solution. I never would have imagined that doing that, with such a new and stable system, would make any difference, since I don't have a legacy of older drivers dotting my hard drive. In any event, I'm really grateful that you guys took the time to try to help me.
In the interest of completeness, here's the relevant portion of my system info after doing the reinstall steps I mentioned above:

As you can see, the Microsoft Basic Render Driver still appears as a Video Card in the list. This presumably has something to do with Windows 8, and I really don't know if its presence here is still a sign that my card is not being used to its optimal capability. I have a hunch that the slight lag that I am still experiencing with the brush when Use Graphics Processor is on -- totally absent with the acceleration turned off -- implies that Photoshop is still unable to take maximum advantage of my card. I would assume that the brush tool should be more responsive with acceleration on than off, in a rig without any issues, but that's just assumption on my part. If you turn off Use Graphics Processor on your systems, is the brush tool more or less responsive?
But again, panning the canvas with the hand tool is now extremely responsive, without any screen tearing or visible lag, and that's a massive improvement over the total meltdown of performance I was suffering from before.
Thanks again very much for your help. I'm grateful to all of you who took the time to chime in.

Are there Issues with poor performance with Maverick OS,

Are there issues with slow and reduced performance with Mavericks OS

or
this:
https://discussions.apple.com/message/25341556#25341556
I am doing a lot of analyses with 10.9.2 on a late 2013 MBP, and these analyses generally last hours or days. I observed that Maverick is slowing them down considerably for some reasons after few hours of computations, making it impossible for me to work with this computer...

Extremely Sluggish Performance

After initially having MUCH trouble actually upgrading to Leopard, including the disabling of application enhancement software, I had to re-install using Archive and Install - I've worked with Windows and OSX for years and Leopard has been the most ill-prepared, poor quality upgrade procedure I've ever used.
Not only that, but the performance is awful on my 1.67Ghz PowerBook G4. Instead of being a step up, I've stepped down: It's much slower than Tiger, CPU usage bursting through the roof, meaning my laptop runs MUCH hotter, and much more sluggishly. Repairing permissions takes 20 minutes! What a joke!
Unless Apple can provide a solution, I'm wiping my drive and heading back to Tiger... unbelievable, it really is.

Please don't flame me for this, but I've noticed that bar one, everyone on this thread are mostly using G4's? Tiger was built on PPC architecture so it was optimised for that system. I seem to remember that the G4 powerbooks just before the went Intel had buss speeds of just 167MHz? The newer Core Duo 2 processors are now at speeds of 667MHz- quite a significant hike. So it's hardly surprising that you folks are having performance problems.
The crux of it, is that Apple want (and have) to sell computers (fair game), and I suppose also that they want you to upgrade to their faster chipsets too (and why not?- they really move!). Yes of course a PPC version of Leopard has been made available that will just work with older PPC based Macs so I suppose you can't really blame Apple for optimising Leopard for Intel chips can you?
I upgraded from a G4 500 Ti which for a good 5 or so years was a great computer with OS 9.2.2 running well and had a 'decent', if a little slow at times performance with OS X 10.3.9- but the speed was beginning to show when Tiger appeared and I had to throw away the Dashboard altogether because I then had to wait several minutes to get Dashboard working at all.
My recommendation is just to go back to Tiger for now until you can afford to upgrade to the Intel architecture. But the Intel Mac comes really recommended. These machines really do 'fly'. The screens are also so much better and brighter than those old G4 machines. Everything just works so much better.

Sluggish performance with OSX 10.9.2?

Since the automatic download of OSX 10.9.2, Cloud 2.0.1, and Tunes 11.1.5 on 26 Feb 2014, I have had prolonged periods of "sluggish" performance on my iMac; slow to open Safari and my home page, very slow sending of email and frequent need to re-enter "sites" to get to the location.
I have brief periods where operating my iMac is a "breeze;" instant connection to Safari and my home page, quick sending of email, and instant entry to web-sites I selected.
And, when I've tried to re-store my 5 and 5s iPhones on iTunes due to rapid battery depletion; I'm informed that "tones" that I've used on the iPhones previously cannot be "copied" to the iPhones.
Any similiar problems? Suggestions?

Extremely Slow performance with X58 Platinum

I just upgraded from a core 2 quad 6600 with 8 gb of ram
to a core i7 920 on an X58 Platinum with 12 gb of 1333 ram (yes the ram is an approved spec according to the MSI online manual....I checked the part numbers on the ram)
I have an 9800gx2 and a velociraptor for a system drive, I have all the latest windows updates(vista 64) and the new 1.1 bios revision...and all the graphic card updates and chipset updates from intel
It is running so slow that as I type this the letters on screen cannnot keep up with my fingers, and I am not that fast of a typer.
It fells like I went back in time to a p3 or something.
Where should I begin to diagnose the problem??
Thanks in advance

I too have stepped back in time with my x
MSI x58 platinum board
Specs
Motherboard Name MSI X58 Platinum SLI (MS-7522)Bios 322
3 GIG Ram Aeneon AXH760UD10-16HA08X
CPU Type QuadCore Intel Core i7 920, 3800 MHz (21 x 181)

OS Microsoft Windows Vista Ultimate(64 Bit)
I am running Raid 0 and performance is just terrible.Overclocks like a champ but the board is pretty much useless when it runs slow.
Things I have tried installed BIOS 322 which brang boot time to desktop to 1 minute 45 secs slow but ok I guess,some improvement in a couple games.
Installed XP64 no help or performance gain.
Windows 7 would just not install any drivers at all.
Vista 64 8 installs with no performance with different drivers.(You can install drivers off usb stick)
Bought a new Motherboard but I am going to wait a few days more and see if others BIOS will help.
There seems to be a few new BIOS I will try some them out today.
Contacted MSI tech support and they were kind enough to suggest the bios,you can give that a shot and see if it helps you out.My board is Platinum SLI board but should be same as Platinum board also but they have all the platinum BIos there too.
Regarding your concern,please log into following link to download and update to the latest bios A7522IMS.322:
-ftp link, username, password removed--not for public release
We would suggest you try to update the BIOS by using USB Bootable pendrive.It is convenienct for you:
1.First of all,please make a bootable USB.You can download USBoot.rar from following link.Then please unzip this software and install it to make a booting USB device:
--ftp link, username, password removed--not for public release
2.Next go to our website to download BIOS file, then copy “AFUD4281.exe” and “A7522IMS.322” into USB.
3.After that, restart PC, press F11, choose USB booting under “boot sequence”.
4.Under DOS mode, please type “AFUD4281.exe A7522IMS.322”(without the quotation marks)and it will be updated successfully!!
Remember to clean CMOS and Load Optimized Defaults under bios setup after you finish the BIOS update!

Premiere Pro 7.2.2 - 10.8.5 - Sluggish Performance (with a Bluetooth twist!!)

Hello all -
I've BOLDED all of the relevant info for the ADD poster children like myself.
I'm having performance issues with PP 7.2.2 running on a Mac Pro 2010 2 x 2.4 GHz (full specs below). The issue makes PP pretty much unusable, and I'm 100% certain it's a CC thing, because CS6 isn't showing any of the same symptoms. Whenever I switch from one window to another (sequence to source monitor, source to program, load a clip into the source, etc) I cannot scrub through the footage or sequence. It takes PP 5+ seconds to "catch up", and then it scrubs just fine in whichever window I've just switched to; UNUSABLE.
Now here's the catch (and trust me, it's a weird one!). If I am using PP and connect my Mac Pro to ANY Bluetooth Speaker, it works just fine! No sluggishness, runs like a charm and becomes the PP I've come to know and love (and I come from the Avid world, so that's saying a lot). However, this presents a major issue: bluetooth introduces 1/2 second or more of delay in the audio, which makes cutting to music very frustrating, to say the least.
Now I don't know how far down the rabbit hole I want to go with this issue, but I'm guessing it has something to do with Core Audio and/or PP just doesn't like the Mac Pro's audio hardware (maybe a driver issue?). Again, if I use anything BUT a bluetooth sound device, the issue reappears. It's a real chin-scratcher.
My specs:
Mac Pro 2010
2 x 2.4GHz Xeon
24GB RAM
10.8.5
PCIe SSD system drive **
EVGA GTX 760 2GB **
PP CC 7.2.2
** I know the graphics card is not officially supported. To be clear, and rule out the SSD and the GPU, these issues were present and more prevalent before these two recent upgrades.
Cheers, and thanks for your help

Glitchy and extremely poor performance with Red footage in AE on 16 core machine

Hello,
I have set up a new Windows 7 workstation for AE CS6 based on:
- ASUS Z9PE-D8 WS with dual Xeons,
- 64Gb. of RAM
- Nvidia Quadro K5000 (also tried my older Quadro 4000 with no difference in results)
- Nvidia GTX 680 (mainly for DaVinci)
- BMD DeckLink SDI
- AE 11.0.2.12 with the latest updates.
- The source footage is sitting on two SSD drives that are raided together.
The problem is that it is exceptionally slow and glitchy when loading Redcode to the viewer and into Neat Video. Whenever I try to load a clip or reposition the cursor, the UI locks and starts flickering - meaning the entire AE UI starts disappearing and reappearing really quickly, so you can see whatever is on the desktop behind appear and disappear. The AE icon in the taskbar also starts flickering. if I click anywhere on the taskbar, AE stops the flickering for a while, though generally after a bit it starts again, until it's finally done rendering the frame and everything goes back to normal. It does better if I set it to 1/4 resolution of course, but that's not particularly useful since I need to be able to feed a full definition frame to Neat Video to set the parameters. Occasionally it actually fails to render the frame and then Neat Video complains.
This is extremely problematic because this was supposed to be an upgrade from my preexisting quad core i7 machine with 16Gb. with HDDs instead of SSDs. Running the same version of AE, that machine works properly and actually vastly outperforms this much more powerful workstation when getting the previews ready from 4K Redcode, so something is clearly not working out on this new installation.
I have spent a significant amount of time investigating the issue, but I'm not getting anywhere. Some of the things I tried:
- Updated BIOS and all display drivers
- Trashed preferences
- Disconnected everything except the disk drives, Quadro and the RME RayDAT audio interface, made a new Windows 7 installation with just Adobe Master Collection and the audio drivers - no extra AE plugins or other drivers. Same behavior, even after disconnecting the RME.
- Tried the latest redimporter from Adobe Labs, made no difference.
- Enabled and disabled multiprocessing
There is a single post from about 2008 in the forum where someone described the same UI flickering. In that case, Logictech SetPoint turned out to be the app that was interfering, but I don't have it installed. Right now it seems like there is something else that's interfering with the redimporter, or else there is a problem running this on the ASUS Z9PE-D8 WS, which I find hard to believe because from the forums it seems like there are a number of people who have also bought this motherboard for an AE platform.
If anyone has good ideas about what might be going on with this problem, or can validate that they have been able to get a good Z9PE-D8 installation running AE to process Redcode, please advise while I keep trying.
Best regards, and thank you in advance.

The workstation has a 1000W PSU and only the Quadro is taxed since it's the main display interface. The GTX680, I believe, is completely idle while AE loads a Redcode frame. According to my calculations, the power consumption should top out at about 850W if the system were really loaded down, which it isn't in this case. I nevertheless tried removing the 680 from the system and it didn't help.
I should restate that it's not the whole screen that flickers - it's the AE user interface. The rest of the desktop is just fine, and in fact if I want I can operate the browser or other apps without a problem even as AE is choking. It's AE that's having a hard time.
The drivers are all the latest from Nvidia, as I stated originally - one install for the Quadro and one for the GTX. I disabled all the stereo vision Nvidia services in service manager.

Extremely slow performance with SR5105 Lockins in LabView 7.1

Hello,
I currently have an application which I've created for controlling a device used in cervical cancer diagnosis. This software has various controls ranging from controlling filter wheels with stepper motors, video capture, lockin data analysis and other various functions.
Everything is working well except the update rate at which I'm receiving results from my 2 Signal Recovery (SR) model 5105 lockins.
SR has provided labview drivers and even a starting interface which works perfectly under normal conditions. However I'm running 2 lockins concurrently and I'm getting very laggy results.
When I run the lockin vi from SR, the update rate is about once every .25 seconds or at least twice a second. When I put the same code into my application the update rate becomes very slow, ranging from once every 3 to once every 6 seconds. I've read the forums thoroughly as well as contacted an NI tech engineer but couldn't resolve this problem. I've heard that there might be a way to change execution settings in labview which would speed this up or perhaps I'm just doing something wrong (I'm pretty new at labview, about a year experience).
I'm including the code that I have. Unfortunately it won't run on your machine because it needs to be connected to proper hardware.
Pretty much I have about 5-6 parallel loops and at the very top you can see two identical copies of the lockin code. What can I do to improve performance? Thanks in advance.

Thanks for your reply. I have actually found a way to fix the problem and it had nothing to do with the subvi's in my application (well almost nothing . The first thing I tried doing was taking out the display local variables which displayed lockin data on 3 screens of my application into 1 separate while loop and replacing the Lockin driver code with global variables which had only the data I wanted to display. This helped a little bit but here's what fixed my problem completely.
When I created 2 lockin SubVIs I forgot to go into File->VI Properties->Execution and there select Time critical priority and in the other option drop down list: data acquisition.
As soon as I did that in the 2 subvi's the lockins actually began performing in real time and now it takes milliseconds to detect the signal and to update the displays.
I hope this helps. I'm surprised the NI Tech rep I spoke with, hasn't recommended this even though I asked if there are perhaps some sort of compiling or priority options in LabView.
Well I'm happy since my problem is now fixed, I just need to get a little more RAM now.

Extremely slow performance with ojdbc6.jar on IBM JVMs (Java 6)

We are consistently seeing slow performance (easily demonstrable by the simplest of test cases) while using ojdbc6.jar on IBM JDKs. Pefrormance is normal when we simply opt for ojdbc14.jar under the same JDK, same java program.
Works well
=======
JRockit, ojdbc6.jar
JRockit, ojdbc14.jar
IBM JDK, ojdbc14.jar
A lot slower
=======
IBM JDK, ojdbc6.jar
All we had to do was to write a simple JDBC access program and measure time taken around
Connection conn = DriverManager.getConnection(jdbcURL, dbProps);
The first 3 combinations mentioned above return comparable numbers. The 4th combination takes 3-4 times as much.
We initially saw this during performance test of our software on WebSphere (also supported on Weblogic). Later was able to eliminate WebSphere and Weblogic as the problem areas and narrow it down to the JVM. Reproduce-able on development machines.
We have been using Oracle/WLS since BEA used to market 'Tengah' servers. This is the worst we have seen as far as the qaulity of support staff goes. We first level support seems clueless. We filed this case and the support comes back tells us that IBM JDKs are not supported for WLS! Oh, we have been running WLS/AIX/IBM JVM combination only for 5+ years.

A quick solution to test this would be to do the following:
mv /dev/random /dev/random.bk
ln /dev/urandom /dev/random
Note: The quick solution will disappear after a reboot. You could add it to rc.local to automatically make this change, but I wouldn't recommend it.
The following is from [http://www.usn-it.de/index.php/2009/02/20/oracle-11g-jdbc-driver-hangs-blocked-by-devrandom-entropy-pool-empty/]:
"Oracle 11g JDBC driver hangs blocked by /dev/random – entropy pool empty
On a headless (=without console) network server, the 11g JDBC driver used for (java) application connect may cause trouble. In my case, it refused to connect to the DB without any error, trace or log entry. It simply hung. After several hours, it connected one time, and freezed again. Remote debugging done by the development clarified that it locks after calling SeedGenerator() and SecureRandom().
Reason: The JDBC 11g needs about 40 bytes of secure random numbers, gathered from /dev/random, to encrypt its connect string.
But public-available “man 4 random” says:
When read, the /dev/random device will only return random bytes within the estimated number of bits of noise in the entropy pool. /dev/random should be suitable for uses that need very high quality randomness such as one-time pad or key generation. When the entropy pool is empty, reads from /dev/random will block until additional environmental noise is gathered.
So far so good, now the question arises: Why does this mystic “entropy pool” runs out of gas?
The answer is as simple as unsatisfying: because too less entropy “noise” was generated by the system. You can check the “filling level” (maybe zero?) of your pool and the overall size of the pool (usually 4096) by issuing
cat /proc/sys/kernel/random/entropy_avail
cat /proc/sys/kernel/random/poolsize
Hint: /dev/random will deliver one new random number as soon as the pool has reached more than 64 entropy units.
So why does my box not generate more entropy noise?
Because only few drivers will fill the entropy pool, first of all keyboard and mouse. Sounds very useful on a server in a datacenter, isn’t it? Some block device and network drivers seem to do so as well, and I have read from guys on the net changing their network card and driver to enjoy this “feature”! But let’s stop ranting, /dev/random is simply made for high security randomness, and if it can’t make sure that randomness is as good as possible in this deterministic world, it stops. Intelligent people have created /dev/urandom for that, like “man 4 random” clearly states:
A read from the /dev/urandom device will not block waiting for more entropy. As a result, if there is not sufficient entropy in the entropy pool, the returned values are theoretically vulnerable to a cryptographic attack on the algorithms used by the driver. Knowledge of how to do this is not available in the current non-classified literature, but it is theoretically possible that such an attack may exist. If this is a concern in your application, use /dev/random instead.
Now let’s get back on our JDBC problem. Oracle JDBC 11g seems to use /dev/random by default, which causes usually no trouble on clients running with console access by a user, because his/her unpredictable :) actions will keep the entropy pool well-fed. But to make it usable on a headless server with a latently empty entropy pool, you should do several things, in descending security order (without warranty):
1. Involve an audio entroy daemon like AED to gather noise from your datacenter with an open microphone, maybe combine it with a webcam noise collector like VED. Other sources are talking about “Cryptographic Randomness from Air Turbulence in Disk devices“. :)
2. Use the Entropy Gathering Daemon to collect weaker entropy from randomness of userspace programs.
3. Talk your JDBC into using /dev/urandom instead:
-Djava.security.egd=file:///dev/urandom"

Sluggish Performance with Tiger

I just installed 10.4.4 on my 20" iMac 1.25 GHz (725MB RAM) and everything seems sluggish - poor performance. Additionally, I am now having CD reading problems. I've tried disk utility and cocktail, but things still seem slow.
All advise is welcome.

Try booting from the Tiger installer disc and try repairing the hard drive from there. Run a repair for permissions as well.
What did you use Cocktail for? Deleting caches?

Extremely slow performance with NEW hdd

Ok guys, this is pretty frustrating. Today I bought 2 new external hdd's, same manufacturer, same model. One of them seems to work great, but the other one.. well look at this:
/dev/sdk1:
Timing buffered disk reads: 96 MB in 3.04 seconds = 31.53 MB/sec
bash-3.2# hdparm -t /dev/sdj1
/dev/sdj1:
Timing buffered disk reads: 4 MB in 4.30 seconds = 951.52 kB/sec
As you can see, my sdj is extremely slow - what could possibly be wrong here?

Airport Express and USB Hard drive and extremely slow performance

HI Guys,
I seem to having a lot of trouble with an Airport express and a Lacie 1TB drive. While I have solved several problems by updating firmware and enabling journalling on the Lacie, I am still having problems with extremely slow performance with my macbook, particularly using itunes and Firefox.
Any ideas and any further information needed?
Regards

HI,
I formatted it using the Lacie setup program for Mac and later enabled it for journalling using Disk utility. This seemed to solve a lot of the recognition problems I was having, however the I-Tunes and firefox performance is still atrocious. If I do Need to completely reformat it using Disk Utility, will I lose my files on the disk now?
not if you move them to a temporary location before you start.
yes, you are better of formatting the drive with DU.

Performance problem with Mavericks.

Performance problem with Mavericks. My Mac is extremly slow after upgrading to Mavericks. What can i do to solve that?

If you are still experiencing slow down issues, it maybe because of a few other reasons.
Our experience with OS X upgrades, and Mavericks is no exception, is that users have installed a combination of third party software and/or hardware that is incompatible and/or is outdated that causes many negative performance issues when upgrading to a new OS X version.
Your Mac's hard drive maybe getting full.
Do you run any antivirus software on your Mac? Commercial Antivirus software can slow down and negatively impact the normal operation of OS X.
Do you have apps like MacKeeper or any other maintenance apps like CleanMyMac 1 or 2, TuneUpMyMac or anything like these apps, installed on your Mac? These types of apps, while they appear to be helpful, can do too good a job of data "cleanup" causing the potential to do serious data corruption or data deletion and render a perfectly running OS completely dead and useless leaving you with a frozen, non-functional Mac.
Your Mac may have way too many applications launching at startup/login.
Your Mac may have old, non-updated or incompatible software installed.
Your Mac could have incompatible or outdated web browser extensions, plugins or add-ons.
Your Mac could have connected third party hardware that needs updated device drivers.
It would help us to help you if we could have some more technical info about your iMac.

Macbook Pro extremely sluggish with new Wi-Fi service on Lion

I just got new Charter wi-fi service, and my Macbook Pro with Lion is extremely sluggish when loading webpages. The speedtest is fine. Other Windows computers in the area seem to work fine.

Hello there, miwaford.
The following Knowledge Base article provides some great steps for troubleshooting Wi-Fi:
