IMHO, this benchmark actually tells us something interesting. It tells us > that with the anchor thrown overboard, freebsd is nearly as fast as linux. I don't think this is the case. The tester claims to be using FreeBSD-RC1 which has all the mentioned debugging options off. And yes, we should adjust UPDATING in order to remove the (now) misleading writing about the debugging options. I think that the most interesting opionion these benchmarks tell is that we are slow on random, threaded I/O operations. I think we need to investigate more in this direction.
