Performance Issues on 6.3

[Natham]

Hi i have a server with four disk atached, 2 raid 0 and 2 raid 1. Im
getting a low performance on file trasfers  over network to windows
clients  i get only about 30MB/s. Looking at gstat i got both disk are
trasfering 15000kBps each over a gigabit connection(client and
server). How can improve performance for my data server?
