Hello guys, that is my first post to this list.
We are using aufs in a squid + dansguardian box, and thing go really
slow around 4:00pm. We already dissmissed bandwidth bottlenecks, and we
have a lot of RAM in this box (around 4GB).
The ASYNC IO counters looks very different from what we supposed to see:
ASYNC IO Counters:

Shoudn't the close requests be equal to the cancel requests?
TIA
