High CPU usage in diffs

[borekb]

Hi, I'm cross-posting an issue from microsoft/vscode#57697 (comment) which hints at high CPU usage cause by this extension in case of diffing larger files. Props to @alexandrudima for finding it.

Thanks, I'll have a look at this.

Have to disable this extension today as it causes my system to lock up with high CPU usage when opening files with more than 4000 lines. Possibly smaller files but that is where I really noticed it since it would prevent me from even moving my mouse around. Through testing I found it is only this plugin that causes this issue.

I got the same error in VS Code as pointed in #481.
It happened when diffing a yarn.lock file (13k+ lines).

Here's the CPU profile provided by Code, if it helps: KnisterPeter.vscode-github-unresponsive.cpuprofile.txt

@danguilherme Thanks for reporting. Good catch that it happens with large files. It may be related to the LinkProvider and HoverProvider.

I'll look into this when I find some time.

I've been encountering this issues as well the past couple days

I disabled issue scanning for now. This should reduce cpu load.
