Lovely figures, but I'm guessing CPU will be more of a bottleneck when
you run on a server with 24Gb RAM and 4 SSDs in RAID-0 configuration.
The server will allocate so much to cache that everything is
super-quick, and what disk IO there is, will also be super quick. Do you
have benchmarks on a more 'representative' server? Say, a dual core with
2Gb RAM and 4 HDD disks in RAID5 running as a VM image, and SVN running
over http?
