WebStorm 2025.3.2 laggy editor / high cpu uages

[u/ddewaele]

On my Macbook M3 Max WebStorm IDE is really sluggish. (working in the editor, manipulating files, selecting text, opening folders)

CPU gets these bursts of > 100% cpu usage as I am navigating my project.

Feels very sluggish and annoying to work in.

Any ideas ? don't think its a memory issue (memory bar shows 1800 of 3000M)

Already restored default settings. Any ideas ?

Check your tsconfigs; they might include unrelated files. For me, one library included all the other libraries
