To be honest, any half-capable server should be sufficient to shovel data down
the pipe; it's the bandwidth that's likely to be the limiting factor, unless
it becomes ridiculously popular.
I maintain mirrors.uk2.net which is a tier-1 mirror for Arch, and also hosts
other mirrors (CPAN, Debian etc).
Looking at my graphs, it sees an average of 6Mbps outbound over the last week,
with peaks up to ~60Mbps.
Load tends to stay pretty low - for instance, right now:
[dave at mirrors:~]$ uptime
11:15:31 up 210 days, 19 min, 1 user, load average: 0.00, 0.00, 0.00
The load will increase somewhat when rsync'ing mirrors, but not massively
(primarily IO-bound).
So, in summary: your main concerns will be bandwidth and disc IO.
Cheers
