I am somewhat confused by this. How much time did the default DrvFs take? Or did you mean DrvFs when wrote virtiofs?

I didn’t test plan9 because I don’t use it

Devfs = virtiofs(for this test ) . Drvfs is the param given to mount , which chooses virtiofs or 9p (plan9/ /slow)

The results above are wsl vhd vs virtiofs, the new file system for accessing windows files . Plan9 /9p is the old one , not tested .
