Data acquisistion slowing down
Hi,
I am using two different while loops to collect data from a capacitance bridge and a temperature readout. I am using PCIe-GPIB for the capacitance bridge and a PCI card for the temperature readout. Then, i am using local variables to transfer the data to a third while loop. Here , i merge the signals and then write the data to a measurement file. I need one data point every second. When I run the vi, initially i get the speed that i want. But, with time, the data acquisition gets slower for both the devices. The write to measurement file data indicates such. I have attached a snapshot of the vi i am running. Need your help with this ...
Thanks
Sakib

Data Acquisition slowing down with time.PNG 46 KB
Constantly opening and closing a file makes things SLOW. So you will want to get away from using that Express VI. Learn the File IO palette and also the String palette. Between those two, you should have everything you need to log your data. Be sure to create/open your file before your loop and close it after the loop. You can then write as much as you want inside of the loop.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Sudden slow down in data transfer
I'm reading data from the hard disk on a Target PXI System (8106 RT) and sending it via Ethernet to a Host PC and writing it to its hard disk. I read a chuck of data from the Target, send it using TCP Write function. The Host uses the TCP Read function get the data and write it to its hard disk. Data is being transfer over a Gbit Ethernet. A total of 9 files ranging in size from 700 MB - 2 GB are being transferred. The process moves along at an adequate speed until it suddenly slows down to slower than a snail's pace in the middle of a file.
By using probes (see enclosures) I've been able to determine it take approximately 17 seconds between when the data is read on the PXI to when it is written on the Host. However, an iteration of the loop on the Target has increased to over 3 minutes. The CPU usage on the Target and Host are minimal, less than 1%. Memory usage on the Host is also small. Any suggestions on how to diagnose what has caused this sudden slow down?

Slide3.PNG 39 KBI would recommend using smaller chunk sizes for your data transfers. I would recommend something inthe 10K to 50K range. I have done quite a bit of profiling for sending large amounts of data and I have found that it is better to send lots of smaller chunks rather than fewer large chunks. Also make sure that you are not automatically building up large buffers in your application if you are using shift registers. If you are reading from a file read the file in chunks and send the chuncks. Don't read the whole file in in one read. One experiment I ran resulted in a single read of a large file (2 MB or so) took something like 10 minutes to read it in one read. However it only took a couple of 100 ms to read the whole thing in 10K chunks. Same applies to wrinting very large chunks using the TCP write. You can easily get a timeout if you write 1 MB as a single write because the receiver has not consumed all of the data within the timeout period. However, multiple small writes will reset the timeout for each chunk written.

For people with an unlimited data plan...does it slow down for you after 2GB?
Ive had my unlimited data plan since i joined AT&T back in 2008 when i bought the iPhone 3G...ive been able to keep it for my current iPhone 4 and now ill be upgrading to iPhone 5 and was wondering if anyone else with an unlimited data plans suffers slowing down of data after 2GB? it mite b more than 2GB but it def does slow down...will this continue to happen or it is it just me?

Click the "what you need to know". If you exceed 3GB you will be throttled, and you should receive a text message about it the first time you go over. -
I have the original AIR recently it has really slowed down. Every function usually gets the pinwheel. It is up to date and has 10g of free disk space. Any suggestions as to the cause?

[Solved]Computer slow down and freeze during data transfer syncing
Hello,
Everytime I make a data transfer, my computer slow down, and sometimes freeze during a few seconds, work for a fraction of seconds and freeze again. I don"t understand why.
As an example, here is a bench of files i transfered during a syncing with Grsync
It took about 12h to sync 64Gb.
I've read a lot of topics talking about this problem but nothing works. I tried to switch off the SWAP and setting the vm.dirty_ratio and vm.background_dirty_ratio but nothing works.
I'm making the trasfer between two Western Digital USB 2.0 external hard drive in NTFS.
Does anyone know how to fix this?
Thanks in advance
Last edited by Neldar (2015-03-04 15:54:29)It seems it was beacause one of my external hard drive was about to die. I performed the same operation with 2 Western Digital external hard drive 1To USB3 and it works perfectly.

Why does my data logging program slow down after a while?
A data logging program created with Labview 5.1. Slows down after a few weeks and creates files in the Temp. directory.Computer is Siemens Scenic pro 124 MB ram and AT-MIO-16XE50 Data acquisition board. Also using Solartron Dig. probes and Fieldpoint units.
Any chance that you are using Win 95/88/ME? Those OS's have well documented
memory leaks which will consume all your available memory if an application
is run long enough. Also there are some issues of memory management within
LabView in the allocation of memory.
The solution to the first is to switch to WinNT/2K. The second will be much
more difficult.

TCP_DATAREADY event slows down TCP data
I'm working on some Labwindows/CVI code that communicates with an embedded device using the TCP libarary.
The CVI code is a client that sends requests for data to the embedded server.
The request / response happens in a timer callback.
The code does not use the TCP library callback TCP_DATAREADY event to collect the data. This event has no code in it.
Rather the code running in the timer callback calls ClientTCPWrite(...) to send the request to the server.
Then it waits in a loop and uses calls to ClientTCPRead(...) to collect the response data as quickly as possible.
Most of the time this works well. The TCP_DATAREADY never gets called.
However sometimes, if I do something with the user interface, like drag a window around or something it gets into a situation where it starts
calling the TCP_DATAREADY very rapidly. This has the effect of slowing things waaaay down. No data is read in the TCP_DATAREADY callback so it eventually gets all the data in the loop in the timer callback.
Is there any way to shut off calls to TCP_DATAREADY?
Or is there a better way to set this up?
Thanks,
KirkThe CPU usage goes up significantly when it gets in this "state".
It's not really while you're dragging the window around, rather it seems like causes it to start a vicious cycle where it makes very many calls to the TCP_DATAREADY event.
I put a counter in the TCP_DATAREADY callback. When I start the code that requests data from the server and check the counter it hardly ever counts up. Then if I move the window or click a button that starts some data logging boom! the counter starts counting up like crazy. It's as if my code that is polling ClientTCPRead(...) gets interrupted long enough to allow a TCP_DATAREADY event and from then on it always calls TCP_DATAREADY as fast as it can??
I put a SetCtrlVal(..) in the TCP_DATAREADY event to display the counter and when it gets into the "bad" state it REALLY! slows down.
Not surprising I guess because the user interface update takes a long time.
The reason I'm polling ClientTCPRead(...) is that I want to respond as quickly as possibly to the incomming TCP data. If I knew how often TCP_DATAREADY events are generated I may be able to "centralize" my data reading in the TCP_DATAREADY event.
I tried putting ProcessSystemEvents() calls in various places. Didn't seem to change the symptoms.
Any more thoughts?

Does 'find your iPhone' use a lot of internet? My mobile data is running out ridiculously fast and I need it to slow down! Anyone has suggestions / info?
You should shut down all the apps running in the background and then reset your phone. Double tap the home button to open the multitasking drawer (iOS 6.X) or the multitasking screen (iOS 7.X) if you are on iOS 6.X press and hold one of the app icons and wait for the icon's to start to jiggle, just like when you want to delete an app. Tap the little x that appears in the upper corner of the icons. Repeat until all the icons are gone.
If you are on iOS 7.X once the multitasking screen is open swipe up on all the app images until they are all closed. Tap on the home screen to close.
Then press and hold both the Home and Sleep buttons at the same time and wait for the Apple logo to appear then release both buttons. The phone will restart itself.
If this doesn't help try doing a Reset All Settings reset, you will not lose any data or content or media. But you will have to reset any setting you turned on or off in Settings. This will reset all settings back to factory default. Settings => General => Reset => Reset All Settings. -
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.

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. -
MacBook Pro 13" Late 2011 Experiencing Significant Slow Down After Boot Camp Installation
Okay, so today, after installing Windows 7 on my MacBook Pro via Bootcamp Assistant, I experienced significant performance slow down (fans going at full blast, applications opening after extended periods of time, keystrokes not being registered) when I returned to my OS X partition/second hard drive. I have dual hard drives, one of them being a Samsung 256 GB SSD with OS X Mavericks and the other being my original 500 GB HDD, divided into a 250 GB OS X Mavericks partition and a 250 GB Windows partition. I have the SSD set as my startup disk and I have it located in the main HDD bay. I moved the old HDD into a caddy and placed it where the optical drive normally should be.
After multiple failed attempts to install Windows via USB and Bootcamp Assistant, I decided to reinstall my optical drive and use a Windows installation disk. This attempt proved successful, and I was able to install Windows 7 onto the 250 GB partition I had created for it on the 500 GB HDD. After completing basic setup of Windows, I removed the optical disk drive and reinstalled the SSD and the HDD into their original spots (SSD in the main HDD bay, HDD in the caddy where the optical drive normally is).
After completing this tedious process, I booted my Mac back up using the SSD. However, I noticed something was wrong when the login screen, apps, and nearly everything else on my desktop had slowed to crawl. I decided to check my Activity Monitor to see what the problem might be. Activity Monitor told me that the task "kernel_task" was taking up anywhere from 200-600% of my CPU, which explained the slowdown in performance. I looked around to see if there were others with the same problem as me, and I found that Spotlight Indexing might be an issue, with a potential remedy being move my Bootcamp Partition into the Privacy section of Spotlight under System Preferences. After doing that, I experienced no increase in performance and everything was still going very slowly.
The next step I took was to see if booting into Safe Mode would help the issue. After booting into Safe Mode on my SSD, I noticed that things were back to their normal speeds, with applications opening at the speed they should be and keystrokes being registered instantaneously. However, the fans were still going and had not shut off once booting into Safe Mode. In addition, I checked Activity Monitor and the "kernel_task" in question was no longer taking up massive amounts of the CPU.
At this point, I don't know what to do and I need help in restoring my Mac to original speeds. I may end up deleting my Boot Camp partition as a last measure if all else fails, seeing as I installed Windows in the first place for running a few programs and games that I can live without. However, I'd prefer to not have things come to that and fix things before deleting the Boot Camp Partition. I've heard that if everything runs normally in Safe Mode, then the issue is third-party software. Is this true?
Any help would be greatly appreciated as I am writing this from the MacBook in question in Safe Mode because it's essentially useless in normal SSD operation.1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
Copy a line of text in this window to the Clipboard.
Paste into the window of another application.
Wait for the test to run. It usually takes a few minutes.
Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

We have a report that used to produce a 1000+ page pdf in
about 2 minutes. It has gone to producing a 200+ page report in
about the same amount of time. No change to the data, database,

from
dba_hist_system_event a,
dba_hist_system_event b
where
a.snap_id = b.snap_id
and
a.event_name = 'db file scattered read'
and
b.event_name = 'db file sequential read';
there is the output of the script
C1 C2 C3 C4 C5
.002438964 .002888595 24.6526611 75.3473389 118.435332
So the time waited for full scan(c3) table is most faster than index sequential read(c4:index probe)
I changed the parameter OPTIMIZER_INDEX_COST_ADJ and OPTIMIZER_MODE
alter system set OPTIMIZER_INDEX_COST_ADJ=20 scope=both;
alter system set OPTIMIZER_MODE=FIRST_ROWS_1000 scope=both;
I lauched aigain the script above, but the output shows the result below
C1 C2 C3 C4 C5
.002438964 .002888595 24.6526611 75.3473389 118.435332
this output isn't different than the first one, so does this mean that INDEXES are not well designed or WHAT ELSE?.
Wich parameter could I enable or change to decrease the C4(index sequential read wait time?
Thank you for your help -
Hello, I have iMAC 7,1, 20 inch,
4gigs of ram,
Intel C2D
ATI Radeon HD 2600 Pro 256 MB
HDD 320gig's
iMAC is perfectly runing OS Mavericks (10.9.5), with no lag, and no sluggish working, Multitasking is AWESOME (i have PC, with 8gigs of RAM, GeForce GTX570, etc etc), but i must say this MAC is running way better a way way, faster and I am Loving it!!! I am using it for making music, and video editing, i am Using Final Cut Pro x, Ableton 9, Logic Pro x, and bunch of other apps and it is working perfectly, and i am so shocked how machine old like this can do that stuff better than any PC i had, and not to mention that I use more time on iMAC than on PC, i use Windows PC just for occasional gaming, but that is like 10% of time, so i use my MAC in 90% of time.
So, enough of my iMAC. I am wondering if I update it to Yosemite, will my iMac slow down, and not continue to work like on Mavericks? Will it become sluggish and unresponsive? Will it affect reliability and stability which have on Mavericks? And will update delete my personal data (tons of Logic, Ableton and Garage band projects, and tons of Final Cut Pro projects), Applications (because I have some apps which is hard to find these days)...
I know bunch of you guys would tell me to backup my data, but i don't have External hard drive (they are pretty expensive in my Country), I have some friend who could borrow me External HDD, but they have their data on it, and they mostly use windows.. I did not use Time Machine yet, but i think probably it would format HDD on Macs partitions, so, i will do it on my own guys (don't judge me about that guys please)..
So if someone could answer me that, i will really appreciate that.
Thank you, and best Regards!!

I recommend you upgrade your RAM to at least 8 GB for good performance with the apps you're using. Also keep a minimum of 25-30 GB of free space on your boot drive for optimal system and application performance.
The maximum RAM a 7.1 iMac can address is 6GB, the OP can keep one of the 2GB DIMMs and then add a matching 4GB DIMM. If the OP decides to do this, please only purchase from Crucial or OWC at www.MacSales.com.
However as described on a 8 year old iMac, I'd stay with Mavericks and then when considering upgrading upgrade to a more up-to-date Mac. -
Safari is slow to open and close. It also slows down other apps while it is running. How can I resolve this issue?
From the Safari menu bar, select
Safari ▹ Preferences ▹ Extensions
Turn all extensions OFF and test. If the problem is resolved, turn extensions back ON and then disable them one or a few at a time until you find the culprit.
If you wish, you may be able to salvage the malfunctioning extension by uninstalling and reinstalling it. That will revert its settings to the defaults.
If there's no improvement, continue as follows.
From the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. Test.
