Differences between benchmarks, what meaning?

[Frog2001]

Hello, I have two machines with exact same hardware, software and configuration (i think), however when I run a benchmark I've got great differences.
For example:
Memory transfer speed: machine 1: 1837 / machine 2: 1478
Disk read burst rate: machine 1: 105,39 / machine 2: 2,06 (real??)
Random read: machine 1: 17,51 / machine 2: 2,07

What can possible be wrong?
Open to all suggestions.
Thanks

Well, the difference is indeed quite large. First I'd suggest to try other benchmark tools if they can confirm such a difference too.
