I had this same issue when I first setup samba on our network. I too am 
using a 3ware RAID controller. Do you have "write caching" enabled on 
your RAID controllers? If you do not, this will slow down performance 
quite noticeably.  I purchased the battery backup units for the cards 
and enabled write caching
