Hello, I've a machine with an integrated Intel RAID controller (U320) which uses the iir driver. I have two arrays, one RAID 1 with two disks and one RAID 5 with 8 disks. The disks are all Seagate 320MB/s. The system is running FreeBSD 7.0-RELEASE with 8 processors (2,40 Ghz) and 4GB or RAM.
I have very poor performances, around ~50 MB/s, is it normal ? jci...@bccm-it ~ % dd if=/dev/zero of=blah bs=10M count=100 100+0 records in 100+0 records out 1048576000 bytes transferred in 20.168689 secs (51990290 bytes/sec) Are there any tool to detect what could be the bottleneck(s) ?
