I would be a bit cautious about inferring server tick rates from the performance on one machine unless you are mostly planning to scale to lots of cores rather than lots of servers, since dealing with access latency can otherwise kill many promising attempts at parallelization even when the contention itself is no big deal. It's likely you are already aware of this and have designed the benchmark to compensate, of course :)
