I've tried both and found them much the same once things like journaling
are disabled. This is a cache remember, you get better performance out
of simply dropping corrupted content quickly and re-fetching. A backend
FS which simply marks bad sectors and does repairs async in the
background instead of trying to recover data will work better for Squid.
File timestamp tracking like atime, mtime etc are also useless. Squid
only regards the HTTP timestamps from inside the cached objects, not the
file times.

See my other post. They can gain you a few extra % of speed, but at a
cost of both money and occasional outages.
