What if you try larger block sizes? like bs=1m ?
Do you mean bs=1m for the dd tests rather than anything concerning the file-system (newfs) or RAID configuration?
{if dd} It would take some time to get precise data along those lines (I haven't been dual-booting my machines) but, in the beginning of this project I did tinker with various values for the dd tests. I don't think it sheds any new light on the issue - On the Proliant machine, FreeBSD file-system performance is around 150% of the OpenBSD file-system performance. However, on my i386 machine, they are *much* more closely matched.
If you [or anyone] have[/has] an idea, I will happily perform particular experiments and collect the data for your analysis.
