Hi.

I'm having a problem with IBM xSeries 335 machine.
I made a hardware raid 1. The disk I/O is very low (cp bigfile bigfile.2)
- 2...3 MB/s.
When i broke the hardware mirror, then I/O on one disk is ca 20MB/s.
Tried with FreeBSD 5.2.1-rel and 4.9-rel both custom and generic kernel.
Where is and what is the bottleneck?

I also put some information up to the web:
http://eimar.vykk.vil.ee/fbsd/dmesg-generic.txt
http://eimar.vykk.vil.ee/fbsd/dmesg-custom.txt
http://eimar.vykk.vil.ee/fbsd/kernconf.txt

PS. Please Cc: me, since i'm not in list.
