Just for fun...
5 machines ran lmbench 25 times. Below is the average of the 25 runs.
linux-4x700 = Quad 700 mhz P3 Xeon 1 M cache, 4 GB ram running 2.4.19-rc1.
480r-2x900 = Sun V480 with 2GB ram, 2 900 mhz Ultrasparc III 8 Mb cache running Solaris 8
880r-8x750 = Sun V880 with 16 GB ram, 8 750 mhz Ultrasparc III 8 Mb cache running Solaris 8
e10k-12x333 = Sun E10000 with 12 GB ram and 12 333 mhz Ultrasparc II 4 Mb cache running Solaris 7 11/99.
s390-linux = Mainframe with 1 GB ram, 2 436 mhz CPUs running 2.4.9-37 (I think that's the right revision).

the quad Xeon.

The libc bcopy test uses 8 MB looks good on the 2x900 with 8 MB cache, though
that test is meant to outsize the CPU cache.
