Performance issues after Nova 9

[sgwilym]

After updating to Nova 9 I'm starting to experience some performance issues with this extension. It's hard to pin down and give proper reproduction instructions, but here's what I've noticed:

• The extension struggles to keep up with my typing, ofter only updating contextual information after several seconds.
• One time when opening code actions for a line, I could see code actions for past states of the file, e.g. Add missing function declaration 's', Add missing function declaration 'su' Add missing function declaration 'sub' Add missing function declaration 'subt', etc. all listed at once. Almost as though many LSP servers were active at once.
• This problem seems to get worse the longer a file is.

I'm also experiencing these performance issues post Nova 9.

I'm also experiencing these issues. Most common spot I notice is after a ; newline, the editor'll freeze, as if it's processing something

Turning off completions seems to resolve it, at least for me, but this isn't great

Same here. It is very annoying. @apexskier are you aware of it and are you still involved in this extension? Thanks. 😊

[apexskier]

Yeah, I'm still aware, sorry for the lack of response on my part. I'm hoping to have more time to support this next month, but I'll try to get to any PRs if I see them before then.

Unfortunately, I don't have any immediate ideas on how to fix a performance issue like this, so it'll take some deep diving. Please make sure you're reporting to Panic as well, since it was associated with a major version change.

Thanks for your answer! I will report it to Panic.

I've upgraded the underlying typescript-language-server from v0.5.4 to v0.11.0 (changelog). There's a chance that this will have helped here, please report back.

Haven't noticed issues 2 and 3 in my initial usage (installed today) but I'm experiencing lots of lag and hitches when typing (including rainbow wheel) on Nova 9.3, M1 Pro.

I am experiencing this issue as well and had to disable this extension to be able to type. I do remember it being a small issue a year ago on my Mac Mini with some stalling.

Now I'm on a Mac Studio M1 Max, and while typing, it often stalls and it'll show the "beach ball of death" which spins for up to 10 seconds before resuming and then stalling again soon after if I continue typing on the same line — it seems random too.

The performance issues on Mac Studio compared to the Mac Mini (Intel) is worse.

I'm also experiencing this issue.

[apexskier]

I've upgraded the underlying language server and bundled typescript version, can you check this again?

[lucasfischer]

It's still slow for me.

[Sam-Spencer]

Painfully slow as of Nova 11.4.

I noticed a lot of folks are mentioning performance issues on Apple Silicon Macs, but I'd like to chime in here that my Intel i9 (2.3 GHz 8-core) MacBook is experiencing the same issue. I don't think this is isolated to Apple Silicon.

And, I'm not sure it seems to be a Nova problem as suggested earlier. Disabling this extension resolves all performance issues in the editor -- even when using other extensions that provide completions from language servers.
