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

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

did you run latencytest as root?

I wish it were that simple to fix it. Here's what I said later in this thread:

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.
