Severe performance degradation opening large folders in latest release #79336

  • VSCode Version: 1.37.1
  • OS Version: Windows 7

I regularly have Code open to a workspace with a large number of files in a single folder ( >20k files). I've never really had a problem with that until the latest release of 1.37.1, where I experience severe lagginess in every element of Code UI, especially text response in editor windows and terminal. This occurs even when Explorer sidebar is not visible. CPU usage shows Code using a large percentage of CPU. Previous version 1.37 seemed ok (but not great) for the day or two I had it, and I definitely know 1.36 builds worked just fine for this case. This issue occurs with extensions disabled (it's pretty much impossible to run with extensions at all in this state).

Steps to Reproduce:

  1. Open a folder workspace with a large amount of files. Explorer sidebar does not need to be open.
  2. Observe laggy UI performance, laggy typing in text windows, especially a terminal window. The performance will sometimes improve briefly, before degrading again after performing any action.

Does this issue occur when all extensions are disabled?: Yes
