squid-3 testing

Here's the current stats from a squid-3 test. I'm not terribly impressed.

Throughput wise, AUFS is about the same as squid-2.5. No surprises there.
I'll be interested in seeing how squid-3+coss and squid-3+epoll performs.

But, squid seems to be taking an _awfully_ large amount of RAM: ie,

adrian 5815 7.6 5.9 327452 61472 pts/2 S Aug27 81:20 /home/adrian/work/squid/squid3/src/squid -ND

.. which is for an aufs squid w/ 2gig of disk cache. I'm passing a slow (30req/sec)
datacomm-1 load through it.

Here's something I knocked up which prints the _size_ of each of the mapped
reigons. a reigon with a 0 inode number and no file means anonymous RAM..

.. which, is quite scary. Because:

        Storage Swap size: 1905292 KB
        Storage Mem size: 3791077 KB
        Mean Object Size: 15.49 KB

Now, I'm going to do a little poking to see if I can find where it is _but_
its not showing up in MemPools.

Any suggestions?
