IBM eServer 346 ServeRaid is too slow

Wed Apr 6 07:43:00 PDT 2005

Hi List

I've got Subj and FreeBSD-5.4PRE on it. But RAID0 is too slow:
root at beta:eugene# dd if=/dev/zero of=/var/tmp/1 bs=1m count=100
100+0 records in
100+0 records out
104857600 bytes transferred in 31.949508 secs (3281979 bytes/sec)

Also what does the following mean?
Interrupt storm detected on "irq16: bge0 bge1+"; throttling interrupt
