Compiling VSCode project substantially faster with Panel closed

Question

I recently noticed that my project builds substantially faster with the Panel closed (CTRL+J). It opens automatically on build and I closed it the other day and noticed a huge performance increase. I pretty much use default tsconfig.json configuration. Wondering if anyone else can recreate?Timing with panel open: 19.86s Timing with panel closed: 4.60sI filed an issue at https://github.com/microsoft/vscode/issues/160118

Wanted to add a little more detail and make the link accessible [0] which also shows the output from --extendedDiagnostics. The Panel is the window where the output from a build is shown [1]. It is displayed automatically on build. It's visibility can be toggled with CTRL+J (I'm on Linux) or from View > Appearance > Panel. When it's hidden the build is x5 faster with no other changes.
Wondering if anyone else can confirm faster builds with it hidden?

My initial instinct: are your build artifacts indexed by the git plugin? Try git ignoring everything not relevant.
