In having quite some experience with Samba on MDK, I have found that making use of hdparm to test/tune the drives ends up being the way to get the best performance out of the system; as well, editing the /etc/sysconfig/harddisks config file assists in performance as well. Once you've found the best params for your drive(s) and have rebooted the machine, you may find that you have quite a boost in your levels of performance. Something to also consider is the filesystem type that you're using; with MDK, ReiserFS seems to be the best for overall performance (and for recovery).
