performance tests
Hi list,
I would like to hear some opinions about a configuration: I have a dual Xeon with 2 RAID5 HW controllers, so that from the OS side I have two SCSI disks. I am trying different configurations to see which one has the best performances. The machine will be a file server for a bunch of people. The question is: would you use LVM over a SW-RAID0 between the two SCSI disks? Is native LVM striping that better (in terms of performance I mean)?
Let me know, I'll run bonnie++ meanwhile, but I don't know if it highlights the differences: I should simulate a multiuser stress of the disks. Any advice?
ciao rob

'''Roberto,
creating a striped logical volume with the stripe size equal to the block size of the filesystem should give you the best performamce presuming that you don't have some bus bottleneck.
