Unexpected slow down in VI
I have a large VI that is running data aquisition and control on our system. Recently it has been have some troubles. After running for a period of time (anywhere from a couple hours to several days) it stops updating once a second, and begins to update once every 25 seconds. The data updates are from a UDP stream that is pulled from our system every second. Some version of this VI has been running for on and off for about 9 years and we have never observed this problem before. In this state it also does not respond to the built in 'stop command' - which gracefully stops the whiles loops/data files, however, it can be stopped using the hard execution stop. Starting the VI again after stopping it and it is back to normal with no problems.
This started occuring after we rebuilt the laptop that the VI was running on. We backed up the VI and are running the same version that was running before the system was rebuilt. The slow down does not occur after any set number of data points or time, just randomly. A VI running simultaneously pulling data from the same source as this one does not have any trouble/slow down - this VI is always running concurrently, so it is not a source of the problem. The task manage doesn't indicate that the CPU is bogged down, or that any other applications are running in the background. The computer is on an isolated network with about 5 other machines, all of which are pulling data from different sources.
Is there a way to determine where the VI in it execution while it is running? Anyone else had problems with a VI slowing down after rebuilding a computer? Any hints as to where I should start looking for my problem.
What is the OS? What are the firewall settings? Do you have an updated driver for the network card?
25 seconds is suspiciously similar to the default UDP timeout for UDP read. This might give you a clue where to look.

Slow down issue with Premiere CS4 on a Mac pro
I am having a similar slow down issue with Premiere CS4 on a Mac pro, but I don't have bloated prproj file size.
Here is what I am working with:
Mac Pro intel quad core 2.8ghz
OSX 10.6.7 Snow Leopard
6Gigs RAM
3TB storage between 4 drives, each drive with about 50% free space
I am editing a 10 minute HD video from avchd files. The edited video is very heavy in photoshop files with a variety of different fx including green screen. The system has slowed down to almost a standstill. Anytime I move the playcurser, or try to do any action, it displays the spinning top "thinking" icon and takes 15 seconds to several minutes to unfreeze. I am often forced to force quit and I have gotten unexpected quits several times. The program also freezes on startup frequently.
No other programs are running. When I export with media encoder, it took about 4 hours to complete. The last 4 or so photoshop images I added seemed to tip the program over the edge. It had been slowing down some, but those last few really dropped the processing speed. Before those additions, export took 30 min to 1hr.
I did delete the render files (did not check if the file size was bloated beforehand, oops) but it has not significantly affected my performance.Do you need all of those extra pixels in the stills? Are you panning the full 4976?
Two things to consider are that if you using, say a 1920 x 1080 Sequence Frame Size, you can only see that at any time, regardless of how large the images are in pixels. If there are extra pixels, i.e. the Pan is not using all 4976 pxls., I would Scale to just what you need in PS, prior to Import.
If you are doing any Scale in PrPro, its Scaling algorithms are not as efficient, as those in PS. [Note: CS5 and 5.5 are a major improvement on that statement.]
With many large stills (the max for CS4 is 4096 x 4096, if there ARE extra pixels, pushing those around will use up resources, and quickly. As a test, some years back, I was working on a "photo wall," and was using 4000 x 4000 images. The workstation had no issues with slowness, until I got to the 5th large still. By the 8th, the Project was too slow to edit. I had to wait for everything. Luckily, I have AE, and it handles large stills much more efficiently, and much differently, than PrPro. I just moved to an AE Comp, and completed the Project, finishing up n PrPro, after I Exported from AE.
Just something to think about. With Scaling in PrPro, this is one time, where bigger is not necessarily better.
Good luck,

Applications slow down or unresponsive after upgrade to Snow Leopard..
Since installing Snow Leopard on my MacBook I am finding some software running slowly e.g Safari (spinningbeach ball) or hanging altogether, as well as problems switching user accounts (system hangs and have to force a restart). I have run Onyx and MacKeeper but still probs. Have installed Snow Leopard on my Macbook Pro and IMac without same probs.
Any thoughts anyone?MacKeeper is probably responsible for at least part of the slow down.
Check to see how much free space there is on the startup disk.
Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure you have a minimum of 15% free disk space.
For Safari "beachballs", click Safari from the menu bar then click Reset Safari. Select the top 7 buttons, then click Reset.
Safari third party add ons could be responsible for the lag time.
Safari: Unsupported third-party add-ons may cause Safari to unexpectedly quit or have performance issues -
why can't i access my itunes anymore? whenever i click on it, it makes my laptop freeze/slow down to the point where not even ctrl alt delete works properly and i have to turn the laptop off and then back on to get anything done. it has been this way for the last 2/3 days now and i have uninstalled and reinstalled it but it doesnt work

My iMac 8.1 (10.6.8 ) was slowing down and had recurrent permissions problems, mostly with Java. I backed everything up, and then re-installed from time machine. Now all I get is a black screen which says I need to reboot. Power+D gives me a hardware error message: 4 MOT/1/40000003: HDD-1336 or HDD-1327. When I reboot from the OSX CD and start disc utilities everything checks out OK. When I reload 10.5.2 from the OSX CD everything seems to work OK and no more permissions problems. But then I loose all my email and safari stuff. Anyone have any ideas short of going back to my old PC?

Thanks for the help. No point in fooling around with it any more. Will I be able to use it as a monitor if I get a mimi mac?
Cheers. Don
No unfortunatley it's too old, you are referring to Target Display Mode which became avialble in 2009, your 2008 needs to have the HD replaced. I'd still do that if everything else is OK or you can simply buy a new MM and display or even a new iMac or an Apple refurbished iMac to save money. -
System Slow-Down After Printing
I recently installed Mountain Lion. Over the last couple of weeks I have noticed a significant operating system (10.8.2) slow down after printing with my Epson R3000 printer. This happens after every printing session. When I say slow-down I mean significant delays and dreading "beachballs" when opening applications, selecting menu items or anything else I should choose to do. I'm left with re-starting the computer to get going normally again.After re-atarting I have gone to "verify permissions" and I get approx "5" pages of permission errors, all associated with the printer library in some fashion or another. I then repair all those permissions and re-start my MacPro. The operating system then works as normal and I can use the computer with no problems (until I start printing again). I mainly use the computer for photo editing with Adobe Photoshop CS6, Adobe Lightroom 4 and Aperture 3.2.
I did not have this problem before upgrading to Mountain Lion (and then to 10.8.2). I did not get "significant" permission errors before upgrading. Since all printer drivers for this printer are handled now by Apple via the "new" Software Update process I can't even re-download the Epson printer driver and start over. I'm completely at a loss as to what, associated with the printer function, is causing these "significant" permission errors and subsequent operating system slow down. My printer is almost brand new and was working flawlessly before Mountain Lion. Let me be clear though, I can print fine. My problem is the system slow down after using the print function which I am only guessing has something to do with the "5" pages of permission errors after printting photos (with CS6/Lightroom/Aperture).
Incidently, I am not in any way a computer expert. Verifying and repairing permissions is about all I know how to do that's why I need help. I also just thought I would try the forums first before going to technical support to see what people thought about this.
Again, I repair the permission errors, re-start my system and all is fine. Any further suggestions would be deeply appreciated.When you see a beachball cursor or the slowness is especially bad, note the exact time: hour, minute, second.

xfoI'm (being lazy and) using the older RT app posted on your last thread. I removed the
TimeNow timer from the RT class and used System.currentTimeMillis (as you requested) to
determine the elapsed time during the animation (see "startTest", "stop" and
"movingObject" methods). Also changed the DecimalFormat to NumberFormat and set the
"maximumFractionDigits" to "2" so it will truncate the fraction to two digits (more simple
than before). Made arrangements for the ShapeMovingPanel class to update the
"timerJTextField" during the animation (RT.updateTime method).
The MouseMotionListener is causing the animation to appear jerky and uneven. The
"mouseMoved" method is very busy while the mouse is moving. You might consider recording
the "mousePressed" events instead of the "mouseMoved" events, ie, the events where the user
is attempting to click inside the moving shape. It would allow the app to be more
responsive and might eliminate the uneven motion of the animating shape.

Need some help with Slow Downs in Java3D and Servlets
Hi,
I realize that there is a separate forum for Java 3D, but I posted there, and did not get any response. This is kinda the crux of my program, so I would like to invite anybody on this forum with knowledge of Java 3D and servlets to give it a stab. Between this post and that one, there are TWENTY duke dollars up for grabs.
Thanks.
http://forum.java.sun.com/thread.jspa?threadID=603198Let me have an educated guess.
You calculated the time elapsed before sending in a server request - and at that point you have you updated timeLastStateChange yet, which means by the time of the next calculation of time elapsed this apparent delay is not counted in, hence the slow down in animation rate.
Hope this helps~

Photoshop CC slows down suddenly, for several minutes
Hi!
I have a problem with Photoshop CC. I sit on a 27" iMac, 8GB RAM and an i5 processor, OS X Mavericks, Wacom intuos Pro tablet.
My problem, that suddenly occurs is tha Photoshop CC suddenly slows down to a halt. No error messages, it just gets very very slow. The first sign is that I suddenly cant zoom. I try to zoom, and nothing happens. Then the cursor, still able to move around with no problem, wont change to an arrow when hovering over buttons or menu items. If I open Safari, everything works fine, exept if I go back to Photoshop, then only the properties window will show. Photoshop is like this for up to ten minutes, then suddenly everything happens at once. All the zooming, closing of images if I tried that (with the keyboard), and then it is all fine again.
The problem occurs both when I do complex work with many layers, but also when doing simpler work with just a few layers.
I have 850GB free storage space and Photoshop is allowed to use 5GB of RAM. I usually dont have open more than two pictures at once. I use Lightroom 5, and PS CC as an external editor.
Any ideas how to solve this? It does sound like PS is writing alot to the HD sometimes, but it should not get this slow anyway, and the program does not freeze as in software error. I dont need to force quit PS, I just need to wait it out. Very annoying!
Sorry for my bad English! It is not my first languageTells us a bit more about the work you are doing:
How many layers?
What types of layers? Shape? Text? etc.
Document dimensions?
Bit depth?
File size on disk?
Also, tell us a little about how things are set up:
Where is your scratch disk?
How much free space on that disk?
How much RAM? -
My mid 2011 MacBook Air has slowed down significantly overnight?
Last night my MacBook Air was working fine.
When I went to use it this morning, it has slowed down significantly. It takes awhile for it to respond to trackpad movement or the keyboard. Opening finder is delayed now, opening any app is delayed now. Booting it back up takes extra long now, probably around a minute compared to thirty seconds before.
I've tried an SMC reset, repairing the disk and repairing disk permissions.
From what I can see, the hardware doesn't appear to be failing, but I could be wrong.
Can anyone help me out? What could possibly be going on with my MacBook? How did this happen overnight?Your MacBook Air's memory is not upgradable, and as you already determined unused storage capacity is not a relevant factor.
There are many reasons a Mac may be performing slower than expected.
Back up your documents and everything else important to you before proceeding.
To help determine the possible causes of this behaviour read the following. None of what follows is intended to fix anything, but it will provide the additional information required to advance troubleshooting:
Boot OS X Recovery by holding ⌘ and r (two fingers) while you start your Mac. At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red.
When it finishes restart your Mac and test again for operation. If it's still not behaving as you expect it should, please post the results of EtreCheck in accordance with the following instructions:
Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Go to his website, download and run EtreCheck:
http://www.etresoft.com/etrecheck
Etrecheck will be in your Downloads folder. Open it from there. You may see the following dialog box:
Click Open - etresoft contributes to this forum frequently and can be considered a trustworthy developer.
It will take a moment to run as it collects its data.
Copy and paste its output in a reply.
Do not be concerned about anything that says "Problem" or “failed” or anything else that may appear in red.
EtreCheck was designed to remove any personal information (such as your computer's name and serial numbers) but if you see anything that looks like an email address or any other personal information that should not be divulged to others, please delete or obscure that information when you post the reply.
When you are finished with EtreCheck, quit the program. It occupies very little space, and you can keep it or drag it to the Trash as you wish.
After completing the above please determine if the problems also occur in "Safe Mode":
Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
You must disable FileVault before you can start your Mac in Safe Mode.
Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
To end Safe Mode restart your Mac normally. Shutdown will take longer as well.
To identify potential hardware problems: Apple Hardware Test. -
My mid 2011 MacBook Air fell off my couch onto carpet. Slowed down.
I made a post a few weeks ago about how my mid 2011 MacBook Air slowed down randomly over night. A few days later it randomly started functioning properly again. I was stoked.
Today, I was using my MacBook on the couch, when it slipped off and landed on the carpet bottom up with the lid closed.
The moment I opened it up again, it was back to being slow again.
I ran the Disk Utility, tried repairing it, it said that the hard drive 'appeared to be ok'
But yeah. I'm gonna say it's a pretty safe to assume that the drop has everything to do with the slow response time.
Would anyone happen to know what actually might have went wrong, though?I would think a poor connection of some sort, may be a plug and socket or a soldered joint problem. I think you need to take it in for repair, I cannot think it will be software that is causing the fault, but...... you never know.

New Mac has slowed down dramatically
My mac is only a few weeks old and I have noticed that it has slowed down dramatically. It takes quite awhile for programs to load. The fill-in boxes are not keeping up with my typing and it is getting quite annoying. I am new to Imac, so I am not sure how to go about checking the processing speed, etc. Any help would be appreciated.

I'm having a problem that has only developed in the past week which was during a time when I haven't changed any configurations in that period of time since my son was born a week ago yesterday and I obviously had more important things to do than mess with my network configurations. However, about 2 weeks prior to his birth, in the process of configuring a baby monitoring system with icam source, 3 weeks or so ago, I read that I might be able to improve my internet performance, I ran googles namebench a couple of times and added and re-ordered the DNS servers that had been listed prior to any problems developing based on its' reports. My internet speeds improved as a result of changing those DNS settings and stayed good until the past week. But of course, we now need to use the computer as part of our baby monitoring system and it's not working worth a **** and I'm getting frustrated since I can't put my finger on the problem and I don't really have time to spin around in circles right now. I'm sure it's probably something simple and I can't put my finger on it though. Sleep deprivation is new to me.......
I've kept running log of notes so this is a little deshoveled but I figured the more information I provide the better the chance someone might help me get this solved quickly.
In the last week, since my sons birth, my internet speeds would be okay after restarts and resetting everything, 2.5 Mbps or so but after a 10-15 minutes it starts to slow down to .2-.3 Mbps. I went thru all my network settings, restarted everything, repaired permissions, I've changed ethernet cables reset PRAM, firewall is running, stealth mode enabled, allow signed software incoming connections and my various other programs such as netsessionmac4f3c6b, skype, java, itunes, etc.
All sharing services off and pretty basic login items at startup including growl.
I had AT&T come out and check my DSL line and everything checked out on their end up to and out of the DSL modem based in their equipment tests.
The problem seems to start when I connect my imac (a fairly loaded 27" imac I got in Dec.) First off, as soon as the imac is connected to the modem via ethernet, the old ethernet modem flashes and continues to flash, even right after startup. So the tech thought something was running in the background and I can't figure out what. I looked through login items but don't see anything that would be a problem and am afraid to eliminate everything.
So I created a guest account to eliminate any login items (I think) and in I got 5.69 Mbps right off the bat. But after a minute or two, without changing anything my download speed slows down and I get for example .77 Mbps. The same thing happens with my administrator account on the imac. Fast speeds at startup and more importantly if I change the configuration by switching between ethernet and airport, I get fast speeds right after changing the configuration but after a minute or two I am well below 1.0 Mbps. I've got several network configurations with automatic, airport and ethernet set up in different ways including a clean ethernet connection with the original DNS settings.
I haven't set up an airport only account but that really isn't the way I want to hook up the computer that sits right next to the modem and runs my network. Restarting the old modem and direct connecting the computer to the modem results in the same thing happening.
I connected my ethernet from the (old?) modem directly to my ancient powerbook G4 and I got +5.6 Mbps download but it also slowed down to 300 kbps after 5 minutes or so the first time (old modem?)
Now to explain why I have "old?" listed above. I was then able to get a new DSL modem from AT&T, hook it up just fine, get enormously faster internet service in the 5,000 kbps only to have it slow back down to around 300 kpbs after connected for several minutes.
directly connected to imac-bypassing router
3,500 kbps
after 15 minutes-250 kbps
connected to imac thru router/time capsule with airport extreme
2500 kbps
after 15 minutes=166 kbps
directly connected to an older powerbook G4 with new modem
IP address of 192.168.1.64
5.65 Mbps on speedtest
after 15 minutes=5.67 Mbps
after 30 minutes= 5.59 Mbps
1 hour-5.66 Mbps
Very solid, stable readings for what I am used to. This would seem to isolate the problem to the imac.
directly connected to imac with new modem
IP address of 192.168.1.64
5.8 Mbps on speedtest
after 30 minutes= .60 Mbps-ping takes 250 ms
1 hour= .46 Mbps-ping takes 250 ms
Now a problem that only started last night after I hooked up the new modem and started up my old Time capsule/airport configuration, I got a message that said something to effect of "another device on this network is using computer IP address 192.168.1.64. So I tried manually changing last digit of the IP address on the computer to one number higher and it kept saying the start and end range were incorrect so I shut the airport station down since when it was connected, it would not allow the computer to connect thru the router via ethernet. I did a hard reset on the airport and I got it back up and running just fine but the internet speeds on the imacs' ethernet connections are so slow it's practically worthless. I also checked to see what was connected to my airport on any given occasion, 2 iphones, 2 pads, another imac running upstairs and a newer powerbook running icam source that is supposed to be the baby monitor. Except for the laptop everything can use "802.11n" but the powerbook only connects via 802.11g so I have set the airport to that limiting setting.
Any suggestions? Is there a way for me to log what is happening so I can report in more detail?First thing is to check if the wireless is on a sensible channel: HomeHub doesn't always make sensible choices. Install inSSIDer on your laptop and see what other devices there are around and if there is any clash. Also, try moving the HomeHub around a little, even quite small differences can make a big difference to wireless signals.
You could run an ethernet cable from downstairs to upstairs. Easy to do, but can be a bit unsightly. If most of your devices are upstairs, you could use this cable to connect the modem to the HomeHub. If you have devices both up and down, you may want to keep the HomeHub downstairs and add a switch upstairs.
HomePlug may be suitable for you. If you search Amazon for HomePlug you will see a couple of kits for just over £30. Don't go for an 85Mbps one. A 200Mbps such as the TP-link or D-Link should be much better than wireless, but not as good as a cable.
Depending excatly how many devices you want to connect and where, you can pay more and have a builtin wireless at one end: http://www.amazon.co.uk/Devolo-1408-Wireless-N-HomePlug-Adapter/dp/B00472MMCQ/ref=sr_1_15?ie=UTF8&qi... Or it may be best for you to use the basic devices and add an old wireless router in switch mode. -
I'm about to buy a 27" i-Mac. I would like to connect my 30" Cinema Display to it as a second monitor. What will I need to do that? Will this slow down the overall performance?
The new iMacs do not come with a MiniDisplayPort, they have Thunderbolt, so unless you are talking about purchasing one of the previous generation iMacs such as this refurbished model in the online Apple store, it won't work. And yes, if you are going to get the full range of video resolutions you will need the Dual-Link version.
For details see the store's web page on the Dual-Link display adapter.

Short-circuiting boolean expressions
There is a term used in other languages to describe the behavior of compiled code which evaluates boolean expressions: short circuiting. Basically, it means that if a term in an expression determines its value, then following terms never get evaluate
