Intermittent high CPU usage

#1

I’m not sure if this is the best place to log this, but I’ve been experiencing high CPU usage with Sublime Merge at work on my Windows 7 VM.

It spikes to 96-98% and uses over 100,000K of memory at seemingly random times for a minute or two, then it’ll drop back down to 0% and under 57,000K.

I’m on Sublime Merge Stable Channel, Build 2027.

Hi @chrismay,

Thanks for reporting this issue.

  • Could you confirm whether you have any antivirus applications installed?
  • Are you performing any operations when you see this spike, or is this when Sublime Merge is idling?
  • Did you experience this issue on previous versions of Sublime Merge?

Thanks,
- Dylan

My suspicion is it’s this issue: https://github.com/sublimehq/sublime_merge/issues/847

@chrismay are you using the aero theme on Windows 7?

Some answers to your questions:

  • I do not believe I have experienced this issue before this version.
  • I do not have an antivirus client installed

So far, I haven’t figured out the patterns, however, this is when I notice the spikes:

  • Trying to change branches, with two files conflicting, getting the message that I need to stash changes. It spikes for roughly one minute.
  • I minimized SM, worked on another program, and clicked on the minimized taskbar icon. It spiked the CPU usage and didn’t respond for roughly a minute to two minutes.

The aero theme is a good question, and I’m a little off of my Windows terminology. :slight_smile: If the aero theme has a circular start menu, then yes, it’s using the aero theme.

Update: I added "win32_vsync_enabled": false, to the Sublime Merge preferences, restarted SM, and the spikes continued.

The most recent spike happened when I attempted to pull latest from origin.
