It probably is; in which case all these results would be useless, no?

http://www.gardena.net/benno/linux/latencytest-0.42.tar.gz

I think Arjan is referring to rtl_latencytest.c

So to state the bleedingly obvious, this would make these benchmark results valid.

If you're interested the command I used was:
./do_tests none 3 256 0 1500000000
as root

Which uses a 1.5Gb file during the disk i/o tests since my machine has 1Gb ram.
