Wow. That certainly is a lot, but since you have log_mime_headers. That
sort of explains it.

Can I ask why do you need it? isn't it for problem tracking only?

This is a nice one. Thanks

Do you see problems running in intercept mode? I've read there are quite
a number of drawbacks with this.

I use reiserfs on a 30GB cache.

I have (just bought <1 1/2 week ago) and I've yet to reach that page.
But yeah, you're right, based on his test methods:

on Linux 2.4 with 32 threads, ext3fs is fastest.

scheme FS Mount Opt throughput
aufs ext3 noatime 168
ufs reiserfs noatime,notail 21.4
