Seeing the same after this very last update. 1 core pinned by the shared process, disablingc extensions doesn’t meaningfully impact it.
Version: 1.39.0-insider (user setup) Commit: e0762af258c0b20320ed03f3871a41967acc4421 Date: 2019-09-27T05:26:42.235Z Electron: 6.0.9 Chrome: 76.0.3809.146 Node.js: 12.4.0 V8: 7.6.303.31-electron.0 OS: Windows_NT x64 10.0.18985
I’m seeing this too, right after the very same update; shared-process eats one CPU core.
VS Code version: Code - Insiders 1.39.0-insider (e0762af258c0b20320ed03f3871a41967acc4421, 2019-09-27T05:26:42.235Z) OS version: Windows_NT x64 10.0.18362
Process Monitor reveals that VSCode is constantly doing bad I/O and failing, e.g.
Code - Insiders.exe CreateFile C:\C: NAME INVALID(there’s a constant pattern of commands that repeats indefinitely), perhaps the clean up code is not quite handling I/O stuff properly.Seems to be better for me. (Looks like Electron was revered back to v4 for this version too)
Yes its not available in latest insiders. Will release new one with the fix and let you know.
Definitely Better! Yes, it definitely looks better, cpu-usage-wise.

But… But I can’t help wondering why it was required to go back to year(s)-old versions of Electron, Chrome and Node.js. The 1.39 2019-09-24 version that worked OK has more up-to-date components. And why the extra child process on identical conditions? Just wondering…
Released new insiders. Please check it out.
@John-McClane Windows User Setup for the Thursday build is here.
Lots of
mkdirpactivity in some of the CPU profiles. Can’t find a hint where this originates from./cc @jrieken @bpasero @sandy081
Same Issue I can confirm exactly the same behavior. The cpu usage was absolutely normal most definitely up to the 2019-09-25 release. It definitely started after the 2019-09-27 update.
1 core constantly pinned down by the shared process, Disabling extensions doesn’t meaningfully impact it.

Previous Versions Available? BTW, is there a directory from where we can download previous versions of the 1.39 insider branch? I have been looking but cannot find anything but the latest version. This would temporarily solve the issue for us (high cpu usage and fan noise on top of it). Thanks in advance.
