Slow response to ImaqDxSetAttribute (intermittent)

I use ImaqDxSetAttribute to provide a software trigger to a pair of Basler GigE cameras. I need to coordinate the acquisition of pictures with transitions in a filter wheel. Once completed the passage of filter wheel, I use SetAttribute to generate a trigger of software to each camera (one at a time). After each trip, I use ImaqDxGetImage to capture the image of each camera.

The problem is that I have done on the SetAttribute call. It takes sometimes up to 5 seconds to return the control to my code (but it still generates relaxation). Typical delay time without this pause are ~ 90 milliseconds.

My development environment is C++ CLR in VS 2005.

Comments / suggestions appreciated.

Thanks in advance-

    Thank you for the comprehensive answer. If the speed is the main problem now, theoretically, upgrading the hard drive would be able to increase the speed up to a point. Of course, this would impact speed of normal programs, programs on the web, etc. I also carefully read the document provided Red Rose, and although it is informative, I don't know about most in this paper has been tried.

    Regarding the age of the laptop, age obviously decreases the computer's full performance, and you have little control over this, unless you buy another computer.

    I have an idea of how research and troubleshooting have achieved you, but it is only an idea. I'll link some documents with information that you may or may not be useful:

  • Very slow response OR Executive Panel Test Switch

    Hello

    After you have installed the Developer Suite 2010 we have problems with the Switch Executive Virtual Device Test Panel. The problems has not been seen on old revisions.

    The Test Panel takes about 3 minutes to initialize. This only happens after that MAX was launched and the Test Panel is used the first time.

    In the attached example there is no committed material, the unit is in simulation mode.

    The same slow response happens to TestStand when you try to select the virtual device. Responses of selection after about 6 minutes, means that it takes 6 minutes for a list of all virtual devices available in MAX.

    I have attached the report of support of MAX, the configuration of the IVI, the export file SE virtual device and an example of TS.

    Any help on this appreciated problem.

    Thank you

    Hi Eric,.

    After you run the tool to remove the Corruption of database MAX Test Panel now works correctly and as expected.

    Also MAX launches much faster now than before.

    Thank you very much for your quick help and find the right solution.

    I have a laptop HP DV72185dx of 2.6 years. It has two 500 GB HARD drive. The HDD1 is having very slow response of the week times last 1. I did a HARD drive test in BIOS menu. For HDD1 the quick test stopped at 17% with an error code of 303. Then he went into full test and stopped at 4% with an error code of 305. INTELLIGENT test succeeded. HDD2 passed all three tests OK. Pls advise if it needs a replacement HARD drive. If so, what type of HARD drive me I need to buy. Also is there a program that can ghost HDD1 data to the new drive HARD (I don't want to miss this chance on some software programs that are already installed.

    Note: I have Win 7 Home Premium (64-bit). I guess that my laptop warranty is over.

  • Windows mail-Slow response to any command

  • Right-click for slow response

    I recently started to feel a slow response for right click commands, usually they would "hang" for 3 to 6 minutes. I have seen similar posts and followed the instructions with the following results:

    1. started in Mode safe: the first right-click had a delay of 30 seconds, after the reaction was instant
    2. clean Booted: followed all instructions to eliminate stray services, found nothing specific but the right click to answer somehow reduced to 30-40 seconds
    3 Ran SFC: no problems not reported

    Now, the period is reduced to 20-30 seconds, but it is still longer than before.

    This problem started a week ago and gradually got behind more long until he was sometimes 6 minutes or more. I'm stubborn me for the delay. Once the pop-up window opens hit does not remove it, there's still 2 or 3 minutes. During this time the office is "frozen". Inatalling Service Pack 1 did not immediately solve the problem, and I did a full scan with Kaspersky showing no infection.

  • Someone knows the extremely slow response and delay with "not responding" on more complex web pages after installing updates on Friday?

    Since the installation of 16 Nov received security patches I've known really slow response with Internet Explorer; 2 minutes between web pages on my WIN7 Pro PC and not much better on my VISTA Business PC.  I get expired on complex web pages the context comes up with "program addresses not" or the pop-up at the bottom of the screen asking me to do it again.  The problem is not limited to Internet Explorer, but also prevents Safari to come.   I tried to reinstall WIN7 Pro, but the problem remains.  I'm also not able to run You Tube or other videos.  There is no download or updated or running Belarc Advisor Windows installation problems.  While the problem occurs with Yahoo Mail, it is not an impact send/receive in Outlook.  Does not appear to impact, nothing other than browsing the web.

    Hi ephd,.

    Thanks for posting in Microsoft Communities. The problem description, I understand that the internet works slowly. Provide the following information:

    ·         Have updates you installed?

    ·         You get the error message?

    Follow these methods.

    Method 1: Temporarily disable the security software .

    Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

    Method 2: Follow these steps:

    Step 1: Start the computer in safe mode with network and check.

    Startup options (including safe mode)

    Step 2: If the problem does not persist in safe mode with networking, perform a clean boot to see if there is a software conflict as the clean boot helps eliminate software conflicts.

    Note: After completing the steps in the clean boot troubleshooting, follow the link step 7 to return the computer to a Normal startupmode.

    Method 3: Follow the steps in the article.

  • New machine install, terribly slow response

    I hope someone can shed some light here, I recently built a new NLE for CS5.5 and the thing incredibly slow to load, encode or even responding to an export order.

    A few specs on the new machine:

    Dual Xeon 3.47 GHz 6 core CPU, total 12 hearts, in total 24 logical cores

    Supermicro X8DTL motherboard, intel 5500 chipset

    Registered 24GO RAM in triple channel mode

    Win7 Pro 64 bit with all updates

    Matrox MXO2 capture/playback

    NVIDIA GTX 580 4 GB video card

    Intel LSI MegaRaid SATA raid controller

    Matrix RAID 5 7TB on the RAID card

    Installed software is 5.5 CS suite, Avira anti virus and the Firefox web browser.  In addition, it is a clean installation

    Now for my problems.

    First usually takes about 2 minutes to load from the desktop and is slow to respond after that.  I loaded a second HD 40 consisting of 2 video clips XDCAM HD timeline and a piece of stereo music.  When I export this simple timeline it takes 3 minutes for encoding options to appear, and then once I selected BluRay HD for the screening and the queue, it takes 3 minutes before the launch of Media Encoder.  At the time I write this Media Encoder has been coding for 30 minutes and it is only about 50% done with this second 40 timeline.  For comparison, my old laptop dual core with its unique internal drive takes about 30 seconds to launch the first (CS4 in it's case) and it encodes the same timeline in 4 minutes approximately.

    Something is very wrong here; I hope it is something simple like a bad setting.  The computer itself seems to work very well, and index Windows benchmarks 7.8 outside a C drive slower, to settle at 6.  All material of the project is on the RAID and the programs and the BONES are on the C drive.  Someone at - it ideas?  I'll have to get started on a great project soon and I can't imagine doing on this machine as it is.

    Scott Cooper

    Seehorse video

    Well, I'm getting there with the support of Matrox.  The horribly slow response seems to be largely corrected by disabling the sound surround in the encoder as detailed here:

    "If you find that the switching export format in the export settings dialog box.
    box sometimes takes a lot of time, such that when you switch from Microsoft
    AVI in MPEG2-DVD, rename the SurCodeWrapper.vca file on your system
    (for example, rename the SurCodeWrapper.vca.bak file). This file is
    usually installed by Adobe Premiere Pro in the following folders:
    $ Files\Adobe\Adobe first Pro CS5\MediaIO\codecs\
    $ Files\Adobe\Adobe Media encode CS5\MediaIO\codecs\
    Be aware that after you rename the SurCodeWrapper.vca file, you will not be able
    to export the audio SwCode Dolby Digital, but you will still be able to export
    Audio Dolby. (Ref # 55279 and Adobe Ref # 2603943) ».

    Fortunately, I didn't need a surround sound, I'm not really thrilled to have to eliminate option however.  I still have a few other questions; I hope that I will get to the bottom of them as well.  Oh, I found MAJOR problems with the latest Nvidia drivers, causing a complete corruption of the video screens.  Roll back to version 280.26 solved these problems.

  • Why firefox has slow response when I save images on hard drive?

    I have windows 7 64 bit and Mozila firefox worm 17.0.1. I have the following problem. When I try to save an image from a site (right mouse click and save as) the disk hard from my pc, firefox response is slow. It takes about 6 to 10 seconds. I thought that it was a matter of file size, but it turned out that it was not relevant because it was images of 10 KB to 500 KB. I did the following:
    -clear history
    -clear the firefox cache and the cache folder in my profile
    -Delete the downloads.sqlite and localstore.rdf files
    -J' changed the browser.download.manager.scanWhenDone and services.sync.prefs.sync.browser.download.manager.scanWhenDone false
    -clear the downloads window
    -Disable all add-ons

    After all this, the problem remains
    Then I started firefox in safe mode (help-> restart with the disabled... modules). The problem remains.
    Then I disabled the windows firewall and Microsoft security essentials (real-time protection). I don't have any other antivirus or firewall on my pc. Nothing happened.

    Then, I created a new profile (reset firefox). Nothing happened. A last attempt, then, remained to be done. Restart in safe mode. So I followed these steps.
    I ran msconfig and disabled Microsoft Security Client to start tab and Microsoft antimalware Service on the services tab. So, I did a boot in safe mode with network support and disabled windows firewall. Guess what. Nothing happened.

    I noticed that when I tried to record images, in the process, there was a significant activity of hard drive (the hard drive activity led indicator was constantly lighting) and firefox in the upper left corner, shown the message does not for about 6 to 10 seconds. You understand that saving a picture of 19 Ko in 10 seconds is not normal.

    Is - this problem has to do with the cache? The disc is a SSD (solid state drive). Do you think that it would be preferable to redirect the in-memory cache? (I have 6 GB of total RAM). This problem was also in previous versions of firefox, but I think that with this version, the problem is more common. This is not the case with all the photos, but it happens with more than 65% of the images.

    It also happens when loading a web page, but it could be a question of a heavy web page that uses a lot of resources in my system, while loading. The problem is the same. Constant hard disk activity and it takes time to load the web page. The problem with the loading of the web page, is not as common as with saving images.

    I think it's a question of management of the cache. What is your opinion?

    Thank you.

    The cause of my problem was the jump lists, which has Windows 7. There are two types of jump lists, automatic or custom. Automatic jump lists caused the slow decline in firefox via Windows Explorer. Finally, it was a windows problem exploring and not firefox. Windows 7 introduces many new features that cause slow system performance. In any case, the solution to the problem is to follow the steps:
    1. open my computer and on the address bar paste the path: %AppData%\Microsoft\Windows\Recent\AutomaticDestinations
    2. press CTRL + a
    3. press SHIFT + DELETE and delete the entire folder
    I think the respective windows Explorer jump list is one that begins with 1b4dd67f29cb1962, in which case you do not want to delete the list of every jump in the folder. If you use firefox, download a file and then go to the above mentioned path and view the files by date. The most recent file must be the correspondent with firefox.

    Hello Hans,.

    Yes, you need to upgrade your memory.   You need at least 4 GB and preferably more.  I know that Apple says that 2 GB, but that is the limit.
