Visual studio code intellisense is very slow

Originally #35210 (comment)

I am still facing issues in VS while developing angular applications.
I can give you list of extensions although i understand there are many causes which makes intellisense slow.
I have high CPU usage , Slow Intellisense

Can you guys give me some specific build i can use and without EVEN Sending stats you guys can identify the activity that cause CPU high usage and slow and unresponsive intellisense.

Thanks
Shan

@shanalikhan Does this still happen if you disable all extensions?

[shanalikhan]

Yes for typescript intellisense slow after disabling the extensions
is there any way to get which extension is causing high CPU usage and memory usage ?

So I dont have extensions and this happens for me. It fixes itself when it shows me an error at the top of the page that alludes to something about Chrome crashing or something. Is there some built in code that interacts with chrome?

Anywas still a huge issue for me and others at my company

@shanalikhan Please use process monitor or ps to identify the code or code-helper process with the high cpu usage.

Hi, I have the same problem. Intellisense or even just trying to auto-format my code takes ages. I've noticed I think it's triggered being slow after I save a file.

From looking at my processes, I think it's the ng-template-0.1.7 that's maxed out for about a minute.

@kevfuzz Please open a new issue against that extension

Closing as not actionable without information on which process has the high cpu usage

I have the same issue as well.
There is a 'code' process that jumps to 100% CPU usage for some time whenever doing a typescript intellisense operation

Ah - looks like it might have been the TypeScriptHero extension causing the slowdown. Disabling that made the slowdown go away
