Of course it isn't.  Never trust only one benchmark.

I've asked the Great Bridge folks to run their TPC-C benchmark with both
zero and small nonzero commit_delay.  It will be a couple of days before
we have the results, however.  Can anyone else offer any comparisons
based on other multiuser benchmarks?
