• Windows updates significantly slows down my computer

  Whenever my computer is a windows update that it slow down my computer, I need to run a virus scan that helps a little but it still runs slowly takes about 5 to 10 minutes to restart.

  If your antivirus software is nothing else than the windows Defender - you might want to experiment & uninstall it.

  Visit the support site anti virus and find their methods of uninstalling...  Many antivirus programs really need a separate download program to uninstall them successfully.   When you see that windows Defender is working properly, it's a good indication that you probably have a successful uninstallation.

  Maybe... then your computer might speed up you decide to reinstall the anti-virus program or not.

• VISA read very slow communication

  Hello

  IM using serial communications VISA in my project and I noticed that the reading block works very slowly.
  I have the microcontroller that connected to my laptop through XBee modules.
  Baud rate is 9600 due as a change factor in each component in the line won't make a difference at all.
  Also, I checked that it work with terminal XCTU and its working fine (very fast). so his can not be something else except read VISA.
  Please see VI attached file.

  Thanks for any help,

  If you do not use a stop character, then the read VISA will sit and wait that 100 characters have been received by the COM port or the timeout elapsed (which is probably something like 5-10 seconds long). You can change the time-out period (using a property node) or reduce the number of characters you read each time that the loop runs.

  Without a termination character, you will need to build your own string using a shift register buffer - whenever you make a VISA read, add it to the chain on the shift register and then do some analysis to take control of your microcontroller (e.g. alarm, coordinated) and remove all the foregoing orders of the string buffer (for example if you have started the VI in the middle of a command) ", then you don't want to throw these data).

• Slow down the entire after effects of the project

  Hello..

  Today, I created a project After Effects (without video or audio - so there is no problem with regard to those) and now I want to slow down the whole project without repositioning of all (and there are many) keyframes... entry points and. Is it possible and if yes, how can this be achieved?

  Thank you!

  Thanks for posting your files to a download location. In the future, you might want to avoid using PMs for several reasons. First of all, if everyone else is having a similar problem, they won't get all the details on how to solve the problem. Second, if I go on vacation (we can dream), so you would never hear me until I return. In the meantime, there are a number of highly qualified people here who could solve the problem in the meantime.

  That said, your time precomposition/remap was not working because there was 'shy' layers in the model called 'Final' (I'm guessing it's the one you want to set the timing on). If you disable "shy" to the model before the precomposition elements, you'll catch all concerned layers.

  Here's what the switches looked like originally:

  

  Here is the "shy" switch, you need to disable:

• Svchost.exe is SIGNIFICANTLY slow down my computer

  Hello, I recently went on vacation last week and a half before hand, I shut down my computer, so there are no memory leaks for my era [6 days].  I came home and turned on the computer which ran fine for awhile.  But then my computer started to act, because every once and a while, but this lasted since I got home.  Norton is my anti-virus and continues to tell me that "svchost.exe" using a lot of memory.  I must have at least 15 + svchost.exe process open for what reason so ever.  3 of which are in high use [one to 70,000] and the second at 20,000 and the other 10,000.  The first two [70 000 and 20,000] are both in the category of user name of the 'system' and the third one [10 000] is in the category of user name "Local Service".  I need help to solve this.

  I was wondering if it could be a virus/Trojan horse that has affected the svchost.exe program?

• Wuauclt.exe slow down my computer

  Whenever the Windows Update automatic update Client runs, it significantly slows down my computer.  For this reason, I put automatic updates updated Fridays @ 03:00, so that I'm not on my computer and it should not cause me any hassle during the working day.  However, this is not the case.  It's a Tuesday afternoon and I have wuauclt.exe now works and has downloaded the updates and continues to ask me to install the updates.  It is difficult to run the programs I need for running the job with that.  I've closed several times by the Task Manager: processes tab and it will not be closed.

  How to stop popping up and running ONLY at 03:00 on Friday?

  Sorry for not responding earlier but I never received a notification of any more responses about this until today .

  My preference would be to make manual updates on the site, so I won't warn me, warn me or come at all.

  As Mike has already said, if your on a domain network, you must ask the Admin on how the system is updated.
  If it isn't and you are the person who updates it, then you have to turn off the automatic updates service and set THE " disable automatic updates. I want to update my computer manually. "

  When you are ready to update, and this includes to restart the system so that files that are used can be replaced, and then start the automatic updates service before either visiting web sites Windows or Microsoft Update.
  Security updates are issued the second Tuesday of each month; No updates for Windows security are issued the 4th Tuesday of each month.

  However, this will prevent the installation of any out of band, critical security updates unless you watch ( the Microsoft Security Response Center (MSRC), search for the Microsoft TechNet security bulletins or the pages of Description of Software Update Services and Windows Server Update Services changes in content for 2010 .

  There is also the possibility that SAV is originally the CPU problem through its oversight to this place:

• Lightroom slows down to 4 K monitor

  Hello

  It is a common problem with LR. Speed depends on the number of pixels displayed (the calculation is done on the pixels of the picture). More pixels - less speed. There's not much you can do. You can upgrade your CPU at a more rapid. But you have increased the number of pixel by > 3 - you will not be able to increase the speed of the CPU by 3. Change graphics card does not work for LR.

  So, we all (?) in this forum waiting for more speed!

• "the db file sequential read" waiting for event slow down an application.

  "the db file sequential read" waiting for event slow down an application.
  
  It is a rather strange problem. There is an update statement that hangs on the wait event 'db file sequential read' and until you restart the database, the query works fine. It happens once a week, usually Monday or after several days of large amount of work.
  
  I checked the processor and is fine, memory is very good, although the SGA and PGA have taken maximum memory. Flow of the disc seems to be ok since each another session on the basis of data looks very good.

  and for small tables, you can try adding for example FULL (your) FULL (wsr)

  It can be rewritten in a different way, but it's the fastest way to try how query will be if you rewrite it. Check the explain plan command if certain partially ordered tables are not joined because you can get the Cartesian join, it seems that it will be ok.

• DaqMX wait the next sample causing slow down Clock.vi

  Hello

  I have a question about the proper use of DaqMX wait for next sample clock.

  I read channels analog voltage on a map or pcie-6259.

  I would like to read as soon as possible make your comments between each of these points of single data points.

  I wish I had an error generated if I miss a data point.

  From reading the forums, I've gathered that the best way to do it is using the Timed Single Point material.

  A simplified program that I use to test this is attached.

  If I remove the DaqMX wait for next sample Clock.vi, my program seems to work.

  I added a counter to check the total time is as expected.

  For example, the program seems to work at the speed appropriate for 120.

  However, without that vi, it seems that the program does not generate a warning if I missed a sample.

  So I thought that the next sample clock waiting vi could be used to determine if a single data point has been missed using the output "is late."

  However, when I add inside as shown in the joint, the program seems to slow down considerably.

  At high rates as 120000, I get the error:-209802

  14kHz is the approximate maximum rate before you start to make mistakes.

  My question is: is this the right way to check a missed sample? I don't understand why the wait next sample Clock.vi is originally a slow down. Without this vi, the program does just what I want except that I do not have strict error control.

  My confusion may be based on a lack of understanding of real-time systems. I don't think I do 'real time' as I run on an ordinary pc, so maybe I use some features that I wouldn't.

  Thank you

  Mike

  Mike,

  You should be able to read to return delays errors and warnings by setting the DAQmx real-time-> ReportMissedSamp property.  I think that if you enable this, you will see errors or warnings (according to the DAQmx real-time-> ConvertLateErrorsToWarnings) in the case where you use read-only.  I'm a little surprised that you have measured your application works at 120 kHz without waiting for next sample clock (WFNSC), although I'm not surprised that it would be significantly faster.  I think if you call read-only, you'll read the last sample available regardless of whether you would of missed samples or not.  When you call WFNSC, DAQmx will always wait for the next, if you are late or not sample clock.  In this case, you will wait an additional sample clock that is not the case in read-only.  Once again, I expect that, in both cases, your loop would not go to 120 kHz.

  Features real-time DAQmx (hardware Timed Single Point - HWTSP) are a set of features that are optimized for a one-time operation, but also a mechanism to provide feedback as to if a request is following the acquisition.  There is nothing inherently wrong with using this feature on a non real-time OS.  However, planner of a non real-time OS is not going to be deterministic.  This means that your app 'real time' may be interrupted for a period not confined while the BONE died in the service of other applications or everything he needs to do.  DAQmx will always tell you if your application is to follow, but can do nothing to guarantee that this will happen.  Thus, your request * must * tolerant bet of this type of interruption.

  There are a few things to consider.  If it is important that you perform the action at a given rate, then you should consider using a real-time operating system, or even with an FPGA based approach.  If it is not essential to your system, you might consider using is HWTSP, where you do not declare lack samples (DAQmx simply give you the most recent example), or you could avoid HW timing all together and just use HAVE request to acquire a sample at a time.  What is appropriate depends on the requirements of your application.

  Hope that helps,

  Dan

• increase speed visa read write

  Hi guys,.

  I use the visa read and write the example, but I am facing a problem when using it in a software expansion, and I can receive only date when the vi has been slown down (using the bulb).

  The program really works on her own with the defined settings.

  So, do you have any ideas/suggestions on how to significantly increase the speed of this vi (joint)? In addition, it seems to create a problem with the playback of data

  Thank you very much

• MacBook Pro slows down to a halt when plugged via magsafe.

  Hey guys.

  I had this strange problem lately, which started about 2 weeks ago.

  My Macbook Pro works perfectly as it is not plugged into the magsafe adapter.

  At the time wherever he is plugged in, it slows down to almost a halt with hiccups etc beach ball. From the MBP place goes from 15 to 20 seconds (unplugged) to 3-5 minutes (connected with magsafe)

  Now, I thought initially it was a hardware problem, but then I did a complete reformat and reinstall:

  I actually did 3 reformats full (the first two I have zero'ed my data) AND reset the SMC and the PRAM twice:

  The first reformat and reinstall brought back my MBP of El capitan to Snow Leopard. Meanwhile, first to reformat and reinstall the system, it may have showed signs of it still be afflicted by this slowness and beach ball gasp he showed before the reformat and reinstall. I kept the first reformat and reinstall for maybe 30 minutes in which I decided to reformat and reinstall once again, that I did not like the name of the Home folder.

  The second reformat and reinstall, I did notice one problem with the system, in fact it was running flawless both disconnected and connected via magsafe. I pulled up to the PS4 and played a few BF4 while I downloaded and reinstalled all the updates, then I upgraded to El Capitan. After all was said and done, I was reading how you can do a clean install of El Capitan via a USB port. I wanted to try this, so I downloaded a copy of El Capitan to a USB stick with the manufacturer of disc X and a then reformat (no zero out as starting program with El Capitan does not have it), and did a clean install of El Capitan.

  I didn't restore from back up or anything, the only thing I did was download all my iCloud data, like photos and songs etc. My system worked perfectly for about a week since the reformatting and reinstalling. He had no problem with the connected system or not.

  Now, a week later, the same problem slipped immediately came out of nowhere and the system works like crap when it is plugged. It takes 3-5 minutes to start, instead of 15 to 20 seconds when it is not plugged in. Also keep in mind, this is a new reinstall where I don't have any what garbage on my system. I didn't yet to reinstall all the games on my MBP, or anything like that, and in my opinion, this is one very bare reinstall OS. The total memory used is like 150 concerts against 350 before my first reformat and reinstall.

  So, I'm to the point where I'm racking my brain trying to figure out whether it is a hardware problem. Since the system ran a good week without this post question reformat and reinstall, it makes me doubt that it is a hardware problem. But on the flip side, since I did a reformat and reinstall, it can't be a problem of software either, especially since I didn't install anything the night before this problem appeared.

  My only hope to address this problem is I hope one of you had the same problem and have a solution. If not, it seems that I might need to get a new MBP this fall, which would be a shame this system ran flawlessly and fluidly before this annoying problem.

  Thanks in advance for any input.

  Since you mentioned the snow leopard, I understand that the MBP is an older model (2009 or almost?)... What is the status of the battery? https://support.Apple.com/en-us/HT201585

• Satellite S500-10F - slowed down and need BIOS update

  Hello, I would like to know if anyone can help.

  I work for a Borough Council IT Department, so it is quite safe to say that I know a fair bit on THIS and the side material things. We had an about 12 laptops Toshiba Satellite S500 delivered, 11 x S500 - 11 c and 1 x S500-10F. As we do not yet support windows 7 so he must rebuild in Windows XP, install the drivers etc, and send them to schools.

  All S500 - 11 c were built and work without any problem at all. The only difference I see is that the model 10F doesn't have bluetooth so that the model 11 c. Model 10F take image ghost, created from the 11 c, but he likes to be restart every 5 minutes approximately and is extremely slow.

  So I rebuilt the model 10F using our licenses CD XP SP3 Microsoft and started to install drivers etc. When I installed the software of card reader Ricoh the laptop again slowed down (about 5 minutes to start Windows). I used to have a similar problem with a model on the A300 range and I've updated the BIOS which cured the problem. I downloaded the one and only BIOS update on the Toshiba site for the S500 and when I want intsaller, he returned with a message that says "this computer is is not supported.

  If someone at Toshiba can tell me where I can get an update of the BIOS that works for my S500-10F or indeed why my system slowed down to a snails pace after having installed the Ricoh card reader software I would be very grateful. I removed the software and now and disabled without success card reader devices.

  Thank you very much

  I can see for this Satellite Pro model 2 drivers are available. The second is O2Micro controller version 1.1.4.207 card reader.
  Have you tried to install it?
