Similarly useful would be a careful analysis of OpenMP multiprocessor scaling for a variety of parallel numeric computations. Finally, it would be nice to test something to do with network latency and throughput and how those two are affected by firewall rules and simultaneous connections. The question is who is qualified and has the time to do such tests.

Most of the Phoronix benchmarks don’t make much sense. The typical response is “but they are reproducible”. No effort is given to explain the underlying system differences and setups. Its quite sad because I’ve come across sysadmins who’ve made decisions based on what they read at Phoronix.

Since you mentioned the benchmarks linked above aren’t useful – what benchmarks have you seen that you would consider useful?
