It's that lovely time of year where I get to go window shopping for servers. Currently we are using a Xeon x3220 with 16Gb RAM with ~800-1200 users behind it and it's getting hammered on a daily bases (CPU Limited). It was speced for a 10Mb pipe, it handled a 20Mb pipe, but we now have a 100Mbit pipe.
Looking at the wiki the cpu reqs don't seem to add up and cover such a large range of performance that they don't mean much. I'm looking for a good benchmark to judge performance in UT before I start pricing options.
Given that we are a larger site sizing a server is a bit difficult without some sort of benchmark as we already are running a beefier box then most.
