Extension host processes on Mac eating CPU (typing lag in vscode)

[elsigh]

• VSCode Version: 1.4
• OS Version: OSX Mavericks 10.11.6

Steps to Reproduce:

1. Open my project
2. 

I tried uninstalling plugins but I don't know what to do that might be less of a time-suck. Maybe it's indexing for the go plugin or something, but it's making my editor unusable. And vscode without the go plugin is unusable for me too, so it's tricky.

Can you run a ps -p <PID> to get more information about the process, esp its command line. That will allow us to figure out what process is going crazy... Any other insights about your workspace, like what files (go, JavaScript, TypeScript, etc)? Size? etc

I have the same issue...it runs my fan constantly and burns through my battery. (No typing lag, though.)

• VSCode Version: 1.4.0
• OS Version: OS X El Capitan 10.11.6

10:25:09] $ ps -p 78859
  PID TTY           TIME CMD
78859 ??         3:30.61 /Applications/Visual Studio Code.app/Contents/Frameworks/Code Helper.app/Contents/MacOS/Code Helper /Applications/Visual Stu

Note: "Code Helper" also continues to run even after I've quit VSCode.

My workspace is a Node.js module with most js files under 20KB. There are a few big-ish json files going up to 7 MB. The node_modules folder is pretty hefty, at ~300MB, mostly because of some CLDR dependencies.

Funny, I closed VSCode and reopened it, and now I have two Code Helper processes going crazy:

@dwbruhn Thanks for the info. Can pipe the output of the ps -p command to a file? Unfortunately the important bits of the arguments are cropped in your sample...

Same issue here, VSC 1.4.0 osx 10.11.6, without VSC running, Code Helper is consuming 100% of a cpu:

$ ps -p 35565

35565 ?? 15486:08.03 /Applications/Visual Studio Code.app/Contents/Frameworks/Code Helper.app/Contents/MacOS/Code Helper /Applications/Visual Studio Code.app/Contents/Resources/app/out/bootstrap --type=extensionHost

Mine's been running over the last week and has racked up 257 hours of CPU time :)

Here's mine:

  PID TTY           TIME CMD
21572 ??        10:36.69 /Applications/Visual Studio Code.app/Contents/Frameworks/Code Helper.app/Contents/MacOS/Code Helper /Applications/Visual Studio Code.app/Contents/Resources/app/out/bootstrap --type=extensionHost

I let it run for most of the day on Friday and the usage dropped down to a reasonable level, even while I was still working in VSCode. Just started making some edits today, though, and it's back up to ~100%.

@elsigh @dwbruhn so does this reproduce even when you run without extensions loaded (using code --disable-extensions)?

[dwbruhn]

@bpasero Strangely, Code Helper isn't even near 100% today, even though I'm in the same workspace. If I can get it to reappear, I'll try the disable-extensions flag.
