Description
Type: Bug
Formatting any simple 60-line C++ file is sometimes instant, sometimes so long that I give up and try again. I've seen it take 20 seconds or more.
This doesn't depend on contents; formatting randomly takes a long or short time when doing minor changes in the same small .cpp file.

Research direction
Start by reproducing formatting on a simple 60-line C++ file in VS Code with the remote Windows setup described. Trace the provideDocumentRangesFormattingEdits request path and compare repeated minor changes in the same file; done means formatting completes consistently without multi-second delays.
