Profiling it while running on testnet might work, but that would take a rather long time to get data. Is there anyway to speed this up if we only needed to provide relative performance between tests. (in a sense a fast performance regression test). At least in theory, one possibility would be to replay real bitcoin transactions to a test-net-in-a-box network (of maybe a few nodes) that has the real blockchain history loaded into it but then operates at a far reduced hash difficulty in order facilitate running quickly. Are there existing techniques/scripts for some kind of perf testing with traffic that at least approximates real world traffic ? The test infrastructure that ships with bitcoin does not appear to provide this.
