My answer's for c++ but still kinda related.

  • Any solution to this problem? I facing the same. VsCode v1.33 and happens with all extensions disabled as well.
  • Same issue. With v1.33, it got really worse on my end. I'm using Windows 10 Pro 64bit on a 250GB SSD, 16GB RAM and i5-4460 CPU. I don't think it's a hardware issue as it seems plenty imo. Tried complete fresh install after deleting the appropriate files at %userprofile% and %appdata%, same issue. Disabling all extensions doesn't help either. If enabled, all extensions' jobs are delayed way longer than what's shown in the screenshot.
  • I had better luck with the new Microsoft Python Language Server. This may be a stupid thing to suggest, but make sure you're using that. And try a completely fresh project as some settings may be defined in the workspace file, not the %userprofile%
  • I have this issue too. It takes 7s to pop up. I have a brand new laptop and it is worse than on my old laptop which is really old and slow.
  • I also found the "C_Cpp.intelliSenseCacheSize": 0,setting useful
  • @kevinf Good find! It doesn't show up in the Settings...…
