My new system has a 3ware 9650SE-24M8 controller hooked to 24 500GB WD drives. The controller is set up as a RAID6 w/ a hot spare. OS is CentOS 5 x86_64. It's all running on a couple of Xeon 5130s on a Supermicro X7DBE motherboard w/ 4GB of RAM.

Trying to stick with a supported config as much as possible, I need to run ext3. As per usual, though, initial ext3 numbers are less than impressive. Using bonnie++ to get a baseline, I get (after doing 'blockdev --setra 65536' on the device):
Write: 136MB/s
Read:  384MB/s

Proving it's not the hardware, with XFS the numbers look like:
Write: 333MB/s
Read:  465MB/s

How many folks are using these?  Any tuning tips?

Thanks.

Let's try that again with the right address :)


You are using HW RAID then?  Those numbers seem pretty awful for that
setup, including linux-raid@ even it though it appears you're running HW raid,
this is rather peculiar.

To give you an example I get 464MB/s write and 627MB/s with a 10 disk
raptor software raid5.
