Claude Code has been pretty poky for me running under WSL 2 on my Server 2022 box (admittedly, with pretty outdated hardware). It would routinely hang after a lot of use and performance would degrade over time.

Since the last couple of updates I don't seem to have those problems as prominently any more. Plus it seems to have greatly improved its context handling as well -- I've encountered far fewer occurrences where I've had to compact manually.
