Calling spawn is very slow at times

• VSCode Version: Code 1.11.2 (6eaebe3, 2017-04-13T08:03:11.395Z)
  • Shell 1.4.6
  • Renderer 53.0.2785.143
  • Node 6.5.0
• OS Version: Windows_NT ia32 6.1.7601
• Extensions:

Extension	Author	Version
tslint	eg2	0.12.0
theme-material-theme	jprestidge	1.0.1
material-icon-theme	PKief	2.0.3

---

Steps to Reproduce:

1. Start VSCode.
2. Before the left side pane is fully loaded open a recent project.

If the window remains open often it will never open any projects. Other times it stays a blank screen without any folders. Also tested this by disabling all the extensions above.

This seems to be a problem with the updated 1.11.x code. I didn't see this problem before.

@chrispyatfpng Can you run code with the --prof-startup flag and attach the profile here. Thanks

[jrieken]

@chrispyatfpng Please attach as files because the comments gets cropped and also because there are two separate files

[jrieken]

@chrispyatfpng Unsure how you try to attach those files but it isn't working... Just huge, tho incomplete, comments

[chrispyatfpng]

Okay. Trying directly through github.

Spawning child processes seems very slow on your system. We have often heard that is coming from eager AV software...

[chrispyatfpng]

I will do some tests with the AV. Knowing my system environment that could likely be the problem, and likely my problems are just coincidental with updating VSCode. Thank you for the assistance!

@chrispyatfpng Did you find out anything? Does this still happen? Does this happen on every start?

I am experiencing the same issues. Although, node process message that debugger attached almost immediately, VS Codes takes a long time to connect. Additionally, sometimes the node process dies because of a Segmentation fault too.

• app is in a docker container
• container is FROM: node:8-alpine
• node v8.9.1

I'm not seeing the extreme slow response and freeze as I was before. On occasion it is a little slow but that is common for apps on my older machine. I should be receiving a new machine in the next month and I will report back with an update.

Closing this issue in favour of #56644, which also tracks slow startup issues on Windows.
