What sort of CPU load does it run under?
Very high, but the web still feels reasonably responsive in general. The
load average peaked yesterday at 9 but this is since I reduced the cache
size. It hit 30 last week which is when I decided the cache (or perhaps
the hit rate) was too high for the disk.
Ah, sorry I meant CPU load as reported by Squid in %:
"It can be extracted from the "general runtime information" or "info"
cachemgr page. It's the value marked "CPU Usage" "

And being linux is it running AUFS cache_dir?
It is indeed. On reiserfs with noatime,nodiratime,notail and heap LFUDA.
1.7GB RAM cache.

Okay, we've reached the edge of my storage-specific performance
knowledge. I hope someone knows a bit more and can educate us both on a
good fix :)
