vscode: Overall slow performance

Issue Type: Performance Issue

Especially, scrolling using mouse or keyboard is really laggy. I’ve tested file under version control and not under version control. But they behaved almost same. Larger lines more laggy.

VS Code version: Code 1.49.0 (e790b931385d72cf5669fcefc51cdf65990efa5d, 2020-09-10T13:22:08.892Z) OS version: Windows_NT x64 10.0.19041

@Minkyu-Choi thanks for the traces, I was able to narrow down some problematic areas, I will merge this issue to https://github.com/microsoft/vscode/issues/107016 for a broader conversation. Please follow that issue.

@bpasero 1.48.x version scrolls better than 1.49 version.
