How to properly troubleshoot/profile Volar performance issues?

[fabis94]

Volar is running really slow in a project of mine - VSCode Save actions take more than 6 seconds, intellisense is slow etc., so I'd like to troubleshoot/profile Volar to see what causes the slowdown.

But there don't appear to be any up-to-date resources regarding how to do this properly. I found this: #413

It seems to be a bit outdated - It references https://github.com/vuejs/vetur/blob/master/.github/PERF_ISSUE.md#profiling which is not even for Volar, but Vetur - but it does kinda work. The problem is that the profiling traces can't be opened in the browser, possibly because they're too huge? I can never get it to get past "Processing profile" in dev tools.

I feel like performance issues can be pretty common in Volar, so there should be some effort to try to build or improve some troubleshooting tools/scripts that would make it easier to figure out what causes slowdowns.
