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.

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 advanceI too have stepped back in time with my x

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! -
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" -
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

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.

Ratiom_debug.vi 558 KBThanks 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. -
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. -
We are also experiencing extremely slow performance for RoboHelp projects under version control. We are using RoboHelp 11, PushOk and a Tortoise SVN repository on a Linux server. We are using a Linux server on our IT guys advice because we found SVN version control under Windows was unstable.
When placing a Robohelp project under version control, and yes the project is on my local machine, it can take up to two hours to complete. We are using the RoboHelp sample projects to test.
We have tried to put the project under version control from Robohelp, and also tried first putting the project under version control from Tortoise SVN, and then trying to open the project from version control in Robohelp. In both cases, the project takes a ridiculous amount of time to open. The Robohelp status bar displays Querying Version Control Status for about an hour before it starts to download from the repository, which then takes more than an hour to complete. In many cases Robohelp becomes unresponsive and we have to start the whole process again.
If adding the project to source control completes successfully, and the the project is opened from version control, performing any function also takes a very long time, such as creating a topic. When I generated a printed documentation layout it took an astonishing 218 minutes and 17 seconds to complete. Interestingly, when I generated the printed documentation layout again, it took 1 min and 34 seconds. However when I closed the project, opened from version control, and tried to generate a printed documentation layout, it again took several hours to complete. The IT guys are at a loss, and say it is not a network issue and I am starting to agree that this is a RoboHelp issue.
I see there are a few other discussions here related to this kind of poor performance, none of which seem to been answered satisfactorily. For example:
Why does it take so long when adding a new topic in RH10 with PushOK SVN
Does anybody have any ideas on what we can do or what we can investigate? I know that there are options for version control, but am reluctant to pursue them until I am satisfied that our current issues cannot be resolved.
Thanks MarkDo other applications work fine with the source control repository? The reason I'm asking is because you must first rule out that there are external factors causing this behaviour. It seems that your it guys have already looked at it, but it's better to be safe than sorry.
I have used both VSS and TFS and I haven't encountered such a performance issue. I would suggest filing it as a bug if you rule out that the problem is not related to external influences: https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform&loc=en

My macbook is experiencing an extremely slow performance. Everytime i try to do something, the pinwheel symbol will pop up. I do not have an antivirus software until recently, which I got free from school and it said my mac has a virus, which has been quaratined. Unfortunately the problem still persist. Help?
kasturi pryanka,
your current slow performance might have been caused by installing that antivirus software. Have you tried disabling it, to see if that make a difference with its performance? -
Slow Performance with Business Rules
Hello,
Has anyone ever had slow performance with business rules? For example, I attached a calc script to a form and it ran for 20 seconds. I made an exact replica of the calc script in a business rules and it took 30 seconds to run. Also, when creating / modifying business rules in EAS it takes a long time to open or save or attach security - any ideas on things to improve this performance?
Thanks!If you are having issues with performance of assigning access then I am sure there was patch available, it was either a HSS patch or planning patch.
Cheers

Extremely slow performance transferring data over USB with Time Capsule
I have the 2TB wireless Time Capsule. I have it setup as an extension to my current WiFi at home, since I already had a WLAN router. I have an external harddrive (500gig) that I connected to my Time Capsule because I wanted to transfer data from the Time Capsule to the external HD. The external HD is formatted with FAT32 file system, so read/write is no problem.
When, using my MacBook Pro, I navigated to the Time Capsule and dragged files over to the connected USB harddrive (connected directly in the Time Capsule), the performance to transfer is extremely SLOW! It was slower than doing the transfer completely wirelessly (USB drive connected to laptop and transfer wirelessly from TC)!
I do not understand this at all! It should be a simple transfer using the USB connection! When I do a transfer from my laptop directly to the USB harddrive, with it connected directly to the laptop, the transfers are super fast!
What happened? Can someone please explain this or tell me what I need to do?
Thank you!I am still confused here.
My original question was regarding the use of my USB external harddrive. It was connected to the back of the TC. The TC was wirelessly speaking to my WLAN router. Using my laptop (also wirelessly speaking to WLAN router), I navigated to the TC and saw 2 listings - one for the data on the harddrive in the TC and one for the new external USB drive connected to the back of the TC. I wanted to transfer data from the harddrive in the TC to the USB external drive. Based on what I expected, I thought the transfer rate would merely be limited by the USB 2.0 interface that is being used by the external drive. However, I was definitely wrong! The transfer rate (shown by the estimate in time to transfer the data by my MacBook Pro) was doubled to 14 hrs.
Originally, it was only 7 hrs when the USB external drive is connected directly to my laptop and I connect to the TC wirelessly. Weird!
So why doesn't the TC simply transfer the data from its internal harddrive to the external USB drive directly without using any wireless technology?
The second question I have is regarding the setup of the TC itself. I have a NetGear WLAN router and its an "n" router. So the speed is good. I have my TC currently downstairs from the WLAN router. Therefore the TC is setup as simply a wireless harddrive. It speaks through the WLAN router in order to be available to all my laptops in my house. My question is whether it should instead be directly connected to the WLAN router using an ethernet cable? Would this improve my overall transfer rates to/from the TC?
Thanks so much. -
Slow performance with yellow highlight tool
Hello everyone,
My problem is that Acrobat gets extremely slow when using the highlight tool
I have made a pdf fromthe web of 350 pages and is about 6.5 MB big
Now I have already higlighted major parts of the text for about 100 pages
and now Acrobat gets extremely slowwhen using the highlight tool When I want to highlight asentence it takes sometimes more than 6 seconds to transform it into highlighted text. I have already optimised my document but without results.
Why isn't there a possibility to tweak the performance of Acrobat in the preferences section?
Can anybody help me with this problem?I have a Windows XP with more than one Gig of RAM
On my wain HDD there is still 17 Gig free space.
Only Firefox with many tabs open.
I have also tried FreeRam XP to free my ram. That did a great job ,butt I still have problems sometimes with highlight tool. -
Slow Performance with large library (PC)
I've been reading many posts about slow performance but didn't see anything addressing this issue:
I have some 40000 photos in my catalog and despite generating previews for a group of directories, LR still is very slow in scrolling through the pics in these directories.
When I take 2000 of these pics and import them into a new catalog - again generating previews, the scroll through the pics happens much much faster.
So is there some upper limit of recommended catalog size for acceptable performance?
Do I need to split my pics up by year? Seems counter productive, but the only way to see the pics at an acceptable speed.I also have serious performance issues, and i don´t even have a large database catalog, only around 2.000 pictures, the db file itself is only 75 mb big. Done optimization - didn´t help. What i encountered is that the cpu usage of LR 1.1 goes up and STAYS up around 85% for 4-5 minutes after programm start - during that time, zooming in to an image can take 2-3 minutes! After 4-5 minutes, cpu usage drops to 0%, the background task (whatever LR does during that time!) has finished and i can work very smoothly. preview generation cannot be the problem, since it also happens when i´m working in a folder that already has all previews build, close LR, and start again instantly. LR loads and AGAIN i´ll have to wait 4-5 minutes untill cpu ussage has dropped so i can continue working with my images smoothly.
This is very annoying! I will stop using LR and go back to bridge/acr/ps, this is MUCH much faster. BUMMER! -
Sudden extreme slow performance
I have run Tiger on this machine for about 6 months with no problems. In the last few weeks everything has started slowing down noticably. The hard disk is running ragged, constantly reading/writing, from looking at the cpu monitor it seems like the computer is not actually using it's ram and is just reading and writing. I tried clearing caches and that worked for a few hours but the machine now seems to lock up after a few hours use. I get to the point where i cannot open menus, switch programs, or even force quit or restart. Everything locks up - spinning beachball - and the hard disk is left constantly writing. I have 9 -15Gb free out of 40Gb on the disk - i assume this is enough. Playing music and safari is no problem. But I am using iphoto and photoshop as well as other programs in the background. This was never previously a problem and ran smoothly. I know it's fairly vague but if anyone can help..
Hi, Ben.
Thanks. However, it would help to see some of the specific data points from the instructions in those FAQs. Specifically:
1. You wrote: "(the pageins/outs are about equal) but i'm getting REALLY slow performance across the board. "It still sounds like it is "thrashing."1.1. Did you check the pagesin/pageouts per second as described in my "Problems from insufficient RAM and free hard disk space" FAQ? The per-second values can only be found using top as described therein.
1.2. Did you check for a runaway process in Activity Monitor per the "Troubleshooting" section in my "Tuning Mac OS X Performance" FAQ?.
The activity you describe (beach ball, heavy disk writing) has to be coming from somewhere, so checking Activity Monitor as I describe in that FAQ should tell you. Find the process consuming the most %CPU as instructed in the FAQ. Post back the result, i.e. the process name.2. You wrote: "It seems to lock itself up with the hard disk clicking and crunching. Is it possible the hard disk is giving up and so is writing at a very slow speed??? "To check this, see my "Resolving Disk, Permission, and Cache Corruption" FAQ:2.1. Perform at least Steps 1-3 of the Procedure section therein in the order specified.
2.2. Also, review the section therein on "Bad Sectors" to see if the "clicking and crunching" sounds you are hearing are similar to those that generally indicate bad sectors.3. If the disk checks out OK per point 2 above, and depending on what you find in point 1.2 above, the process may be an errant Startup or Login Item. My "Troubleshooting Startup and Login Items" FAQ can help you pin that down if such an item is causing the problem.
Good luck!

MacBook Pro running extremely slow- something with RAM maybe?
I'm using a MacBook Pro, and yesterday, out of nowhere it stated running extremely slow and constantly freezes. I did some research and ended up looking in the Activity Monitor, and it seemed like I have no free space available - so I deleted a bunch of files and the computer is still running exactly as slow as it was before. My stats on the activity monitor are:
Free: 9.7 MB
Wired: 851.7 MB
Active: 2.11 GB
Inactive: 1.05 GB
Used: 3.99 GB
VM Size: 162.33 GB
Page ins: 541.0 MB
Page outs: 4.02 GB
Swap Used: 10.41 GB
Finder says I have 317.3 GB available. What's the problem here?Safe mode prevents almost all third-party software from running such as preference panes, plug-ins, extensions, and launchagents and launch daemons. Normal boot lets all that run. So the issue is with one or more of these third-party items. Perhaps you can download EtreCheck 1.9.10 and run it when your system is at it's worst state. Then post the results here for us to check.

If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
