you might try adding:

socket options = IPTOS_LOWDELAY TCP_NODELAY SO_RCVBUF=65536 
SO_SNDBUF=65536 SO_KEEPALIVE READ_SIZE=65536

        use mmap = No
        use sendfile = Yes
        blocking locks = No
        read raw = no
        write raw = no

kernel oplocks = no
        oplocks = yes
        level2 oplocks = yes
