WSL 2 Is Getting Faster Windows File System Access
Hacker News (AI keywords)·10 days ago·Release
Microsoft is improving WSL 2's Windows file system performance by implementing per-device SWIOTLB (Software I/O Translation Lookaside Buffer) pools for the virtiofs and virtioproxy subsystems. SWIOTLB pools act as bounce buffers enabling the virtual machine's I/O operations to interact with host memory more efficiently. The change reduces contention in shared buffer allocations, potentially delivering meaningful speed gains for developers who frequently read and write files across the Windows–Linux boundary in WSL 2.
