Make sure to know what you measure. With z/VM it may depend a bit... ;-) Dunno about dbench, but I do know that some of these test programs from another universe tend to measure time or timing by CPU loops and then implicitly assume a relation between userland time and wall clock time. Yes, I know this would at best shift the numbers the other way. However, when I ran 'iperf' and 'netperf' benchmarks I found that the timing issue did confuse the programs in such a way that they computed a negative delay between transactions and things like that.
