Issue Type: Performance Issue
It takes over 1 min until the application window shows up. I've made several experiments trying to locate the problem:
1. With proxy server in the VS Code Http:Proxy setting
- Run
code in PowerShell: ✔️️ application window showed within 5 seconds
- Run
code in WSL (Ubuntu 18.04): ❌️ Super slow startup over 1 minute
2. Without proxy server in the VS Code Http:Proxy setting and no system environment variables of HTTP_PROXY & HTTPS_PROXY:
- Run
code in PowerShell: ✔️️ < 5 secs.
- Run
code in WSL: ✔️️ < 5 secs.
3. Turns off proxy server during the startup so to make network requests fail on purpose
- Run
code in PowerShell: ✔️️ < 5 secs.
- Run
code in WSL: ✔️️ < 5 secs.
Conclusion & Questions
So it appears that some kind of network requests blocks the startup process of VS Code. But how comes it happens ONLY in WSL rather than BOTH OF WSL & PowerShell?
I also wonder if I can have an HTTP request list during VS Code startup, so to run some tests to see if there's anything wrong with my proxy server?
I've tried to launch VS Code with --disable-extensions --trace --log-net-log=xxx flags. The output files are attached below. --prof-startup seems not working properly in WSL. VS Code would simply fail to launch with this flag.
