Although I understand your arguing, the OP just said that with ext3 the
process returns after 22s, while on xfs he has to wait 2m20s to have the
command prompt back.
That's not a benchmark, but user experience. I'm also surprised by that
big difference, and given the numbers are correct I would say ext3 does
something "better" here than xfs. I'd guess it's only an effect of
caching, and in thruth the disks are still running like crazy in the
background. But hey, if I decompress a kernel I'm more happy if it
returns after 22s and I can start "make menuconfig", than having to wait
2m20s. The damn thing should write in the background, that doesn't hurt
(in this specific case).
