Is vscode-solargraph reliable/performant for medium-size Rails apps?

Migrated from this issue: #249

I have a 2015 Apple MacBook Pro (and a new M1 MBP on the way, fortunately), and a few teammates of mine have M1 Macbook Airs. All of us encounter the same thing: for our Rails 6 project that we maintain, Vscode + solargraph starts off just fine, but after a few minutes, it just seems to get bogged down, and linting starts to take 5 seconds, then 10 seconds, and then eventually stuff crashes.

Of course, I'd like to get to the bottom of this, but I kind of wanted to take a poll of vscode-solargraph users:

Poll Question:

As a vscode-solargraph user on a Rails codebase: does vscode-solargraph work reliably-enough for you that it's A. fast enough, B. gives correct results, C. doesn't slow down other operations, like running tests or reloading Zeitwerk rails code after a code change, and D. you're not constantly thinking about whether Solargraph is about to crash or in need of a reload?

I'm asking because before I do some perf work on our vscode-solargraph setup, I want to know what's actually possible to attain, or if maybe the underlying technology is still going to be too slow / clunky for things to be fast.
