downgrading to 1.35 or 1.34 fix the issue, tsserver peaks only when I type something.

fotonmoton · 2019-06-25T11:42:59Z

Seems like downgrade do not resolve the problem. After some work tsserver again begin consume 100% CPU constantly in editor with two tabs opened and no action.

sandersn · 2019-06-26T15:50:36Z

@fotonmoton can you do one of the following?

Reduce the problem to a small repro.
Share the code that causes the bug.
Share the tsserver log from when the bug happens (see https://github.com/microsoft/TypeScript/wiki/Providing-Visual-Studio-Repro-Steps#typescript-server-log, and substitute “VS Code” for “VS”).

For [1], it is probably easiest to start by deleting your node_modules folder and checking whether the problem reproduces. If so, then the bug is exclusively in your code and you don’t have to worry about types from packages.

sandersn · 2019-06-26T15:51:30Z

@fotonmoton I assigned this bug to you to gather more info. Please unassigned yourself when you are ready for me to look at it again.

mjbvz · 2019-06-26T21:32:43Z

For VS Code, collecting the TS Server log is actually much easier:

Set "typescript.tsserver.log": "verbose",
Restart VS Code and reproduce the problem
In VS Code, run the TypeScript: Open TS Server log command
This should open a tsserver.log file

fotonmoton · 2019-06-27T09:53:03Z

@sandersn, ok, try to find out in which case tsserver peaks and create repo with code if I find something. @mjbvz Thanks for suggestion!

fotonmoton · 2019-06-27T14:54:40Z

For now I upgrade VS Code to 1.35.1 and can't reproduce described behavior, I enable verbose tsserver log and if something happen will submit output.

marques-p44 · 2019-07-03T12:37:11Z

I'm still having CPU issues as well. I'll attach my tsserver.log output.
tsserver-log-output.txt
Does anything jump out as to why it takes sometimes 8 - 12 seconds to finish typechecking?

sandersn · 2019-07-03T18:43:18Z

@marques-p44 you have a number of packages with performance problems that have recently been fixed, like lodash and styled-components. I believe material-ui might have perf problems, though I'm not sure.

Can you upgrade your dependencies to the latest version and see what perf is like?
Can you open a new bug to track this issue? It's hard to know the root cause for perf problems, but it's likely different from that of @fotonmoton's problem.

mjbvz · 2019-11-06T05:55:16Z

Closing as it sounds like this is no longer reproducible for the original poster

gorjan-mishevski · 2019-12-03T09:24:48Z

CPU at 1000% on macbook pro 2019, running the tslint plugin for intelij

disarticulate · 2022-05-31T23:41:08Z

so uh, this isn't even a plugin, it's just bundled with vscode now, i've had to set:

"typescript.tsserver.maxTsServerMemory": 0,
"typescript.tsserver.useSyntaxServer": "never",

I think vscode realized I was trying to kill it and it spun up and killed my server.
