IE11 CPU is pinned using AbaData2

Internet Explorer 11 is using 100% of its CPU when using your site. This appears to be new, as if either you have changed something on your site or the latest IE11 patch from Microsoft has triggered something to break with your website. This does not appear to happen in Chrome.

    not sure yet if related to September Microsoft patching

  • I ran the F12 developer tools and did a brief 'profiling' session, which I have attached here. It seems the website is continually rendering something in a loop.

  • Hello,
    We have done some testing and are not able to get Internet Explorer to max out the CPU.  We are using update version 11.0.45, as describe above, and while the CPU usage of IE does spike when rendering a graphics-heavy page, it drops down again as soon as the graphics are displayed.  I'm wondering if there might be a layer or something that is causing this behavior. Could you let us know what layers you have turned on?
    Thanks,
    Ed

  • I noticed during testing that my desktop screen resolution has to be more realistic (1024x768 was to small and the problem did not exist like that). I did some testing on a virtual PC but it was not happening until I increased my desktop screen resolution. My current test is at 1280x960. I tried at several others in between and found this starts to happen at 1280x800 or better.

    The attached image shows iexplore.exe at about 50%, because I have 2 cpu's and IE can only use 1.

    Thanks

    p.s. just to be clear this happens on physical PC's that I have tried too. my physical pc is using 1920x1080 for a screen resolution.

  • Hi,
    I'm just not sure what we are going to be able to do on this issue, as we are not able to replicate what you are experiencing.  Although we do update AbaData 2.0 on a regular basis, as far as we know we have not made any fundamental changes to the way the program works that would account for a change in how a browser behaves.  Certainly, IE has always been what we would call the browser of last resort when it comes to AbaData 2.0, simply because the program seems to perform much better in Chrome, Firefox or Edge.  That being said, Even with a screen resolution higher than what you noted, I am still not seeing IE CPU usage at anywhere near capacity.  Sorry, I just don't know where to go with this although if using a browser other than IE is possible, that would be recommended.



    Thanks,
    Ed
