When running Bonnie, you should always set the file size to 3-4
times the size of your RAM, else you get the 200Mb /sec speeds
(which are very pleasant, but not realistic). I think the 100% CPU is
in great part Bonnie generating the test files. I've tried copying files,
this takes almost no
Well, we've been using assorted versions of the 0.90 raid code for over a
year in a couple of servers. We've had mostly good success with both the
raid1 and raid5 code. I don't have any raid5 disk failure stories (yet
;-), but we are using EIDE drives so I expect one before TOO long ;-)

I think the bonnie test at least tells me what max throughput of the
drives and controller's ability to do RAID-5 are. I'll be
happy to run
other benchmarks though. Where can I find tiotest? Searches on

SCSI is SCSI, unless it's differential (LVD, VHVD, etc). So yeah, they
should work just

That is true. This probably isn't worth
I wanted to follow-up that with kernel 2.3.51 I get raid0
performance problems similar to those reported below, but at larger file

I created files of approx. size 256 MB, 512 MB, and 1 GB. I did simple
tests 'time cat file ... /dev/null' on different file sizes/counts,
always totalling
