Hi,
For a host using a Pentium 4 CPU at 2.8Mhz, what is a sensible max value
for number of TCP sessions this host could run under Linux?
Bandwidth per TCP session is likely to be about 10kbytes/second.
To a first order, and assuming that there is nearly no user-space
processing for those TCP connections (TCP is a transport not a session
protocol :) you could take a netperf TCP_RR test result - using the
service demand - usec of CPU/KB transferred you could then do some back
of the envelope calculations as to the number of 10 KByte/s connections
you could support. It would be a bit of handwaving, but give yourself
say a 20% pad and you'll probably be OK.
