Performance issue: general VSCode slowdowns attributable to this extension

Hi,

Recently I have been debugging some performance issues in my VSCode setup, and while the extension bisect tool was not helpful in this regard, after manual extension disabling I've managed to narrow it down specifically to the SARIF Viewer extension. I wonder if others can reproduce this issue?

With the extension on, VSCode becomes generally slower, with the effect being most prominent in the source code view for editing and cursor movement commands, with seemingly a 1 ± .5 second latency being added to everything, increasing typos due to unpredictable interleaving between character-insertion and cursor-movement commands. The source code file need not be saved for the effect to take place (though it's possible that some sort of background auto-saving may be compounding it). It's hard to localize the issue, but during a text-editing freeze I often see a "clock" badge appear on the Source Control tab, indicating a git operation in progress.

I have previously submitted the issue here, erroneously attributed to another extension by VSCode's extension bisect tool. That link contains some more diagnostic info.

It's possible that there is an interaction between this extension and another one I have installed, so here is a dump of my extensions in case it helps:
