Hmm, how are you creating your ext3 filesystem(s) that you test on?
Try creating it with a large journal (maybe 256MB) and run it in full
journal mode.
The filesystem was created during the initial CentOS installation, and
I've tried it with ext2 which made no difference.
The journal size was probably 32MB then. A 128MB or larger journal in
full journal mode on a 3ware card with a BBU write cache should make a
big difference because fsync calls will now return OK as soon as it hits
the write cache....oh....do you have a BBU for your write cache on your
3ware board?
