Your maximum request rate will depend mostly on how full you let the
disks become. If you use 90% of the filesystems, then you'll probably
be down in the 25/sec range. If you use much less, like 25%, then
you can take probably 50/sec.

5 Mb/s of HTTP traffic is about 50 requests per second.
If you have other traffic in the 5 Mb/s, then its probably
more like 30-40 req/sec.

Thats three questions :-)
Cache Digests is probably a good way to share.
