Steps to reproduce

  1. Visit twitch.tv and open a live stream or VOD.
  2. Disk usage jumps noticeably higher than what it does with other browsers.

Expected result: Low disk usage.

update: After some research, I noticed that when watching a twitch VOD the disk activity returns to normal if you skip towards the end where there’s not much video left to buffer. Around 1 or 2 minutes before the video ends disk activity is normal while all the other time it hovers between 20% and 30%. Could it be that Edge is caching/buffering(?) more aggresively than other browsers?

  • Hello,

    Thank you for providing this information about the issue. After thorough testing, we are unable to reproduce this problem in Edge with the information at hand. Please update this case when you can provide more details, such as screenshots or run dxdiag (Windows key + r and type dxdiag, enter, then click Save all Information) and attach the txt file.

    Best Wishes,

  • Greetings,

    I have attached DxDiag.txt

    I have already attached some screenshots showing the difference in disk usage between Chrome and Edge; if there’s anything else useful I can attach I’d be glad to.

  • Hello,

    Thank you for providing extensive information about this issue. Unfortunately, we are still unable to identify or reproduce this problem in Edge. Please open Task Manager and go to the Performance tab, click Open Resource Monitor and expand the Disk section, then sort descending by Total (B/sec) and conduct your repro in Edge. Please note which processes are listed at the top, and attach those results as a screenshot.

  • Hello,

    I attached 2 screenshots from Resource Monitor. MicrosoftEdgeCP.exe is the process with the most disk activity. This issue existed before Creators Update by the way. Also, after asking about it on reddit I couldn’t find anyone to reproduce this issue either.

  • Hello,

    Thank you for this update. We will need to gather some more information to investigate. Please repro the problem in Edge only, and then follow these steps:

    1. Juxtapose the Processes tab in Task Manager (sorted by Name acsending) and Overview tab of Resource Monitor (ensure all the sections are expanded) and take a screenshot; include in the file name "sample1".

    2. In the Details tab of Task Manager, right-click the offending MicrosoftEdgeCP.exe process (it has a PID matching the one found in the Disk Activity section of Resource Monitor) and select Create dump file.

    3. When the dump completes, locate the .DMP file and include “sample1” in the name.
      Please repeat those steps twice more and increment the sample number each time. Please wait about 30 seconds between each repetition so we will have 3 unique samples to review. Attach all 3 samples to this case so we have 6 new files as a result.

    Thank you so much for your assistance with this case.

    Best Wishes,
