I have a lot of experience with benchmarking Linux servers, though not
Gentoo-specific. Do you have some specific questions? In Portage, there
is a whole category of benchmarks, called "app/benchmarks".

$ esearch -Fn ^app-benchmarks|grep \*|more
*  app-benchmarks/acovea
*  app-benchmarks/bashmark
*  app-benchmarks/bonnie
*  app-benchmarks/bonnie++
*  app-benchmarks/contest
*  app-benchmarks/cpuburn
*  app-benchmarks/dbench
*  app-benchmarks/iozone
*  app-benchmarks/jmeter
*  app-benchmarks/lmbench
*  app-benchmarks/ltp
*  app-benchmarks/nbench
*  app-benchmarks/piozone
*  app-benchmarks/pipebench
*  app-benchmarks/siege
*  app-benchmarks/stress
*  app-benchmarks/tiobench
*  app-benchmarks/volanomark
*  app-benchmarks/xfbsuite

For I/O, I recommend "bonnie++" and "iozone". For network, try

*  net-analyzer/netperf
*  net-misc/iperf

I'm not sure what to recommend for CPU; it's really
application-dependent. What is the task these servers are going to
perform for a living?
