WSL3 Performance is about 5-60% faster than WSL2 depending on the workload

Grieving the loss of details
I’ve been thinking about where I stand in respect to the current state of the industry. This is more of a journal note than a post, apologies for that. I usually leave this stuff private, but I thought I’d post this as a trial in case someone relates to this experience and feels less alone. All opinions are my own.

A minimal kernel in Swift, running in QEMU
Update (28th of September 2026) Max Desiatov told me that the @c swift attribute should work, instead of declaring the functions using @_cdecl.
