I can’t find any benchmarks on this, anyone have a sense of the speedup that can be expected here?

And for what it’s worth, that version isn’t available yet when I try to update WSL.

a test compile of hugo (moderate go app) on a AMD Ryzen 7 7735HS with SSD

WSL filesystem = 50s

virtiofs = 75s

it seems a lot faster. I don't use drvfs (windows files) usually. 50% performance gap is good.

And MS Defender kicked in beforehand losing about 10 seconds. with some config you could turn off defender and get this down to 60s

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

[tonymet]

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 .

[tonymet]

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

more or less this is what I ran to benchmark

wsl version 2.7.7 seemed to work with the listed config + reboot
