If the server is a forwarding router, then PPS of 64 byte packets forwarded would be a good metric. If its a database server, then PPS is largely irrelevant. Generally speaking, work out what you want to change, find a good metric to measure the performance change (Eg, change filesystem/tuning options, run bonnie++), measure before and after. Even then, its not that simple, as bonnie++ doesnt accurately represent my FS-related workloads. The ideal way is to find a way of measuring $APPLICATION, since that is what the server is for.
