Maybe you are experiencing the sendfile problem. Using sendfile is the 
default for newer samba versions, but unfortuneately a lot of kernels 
don't implement that right.
Try using
use sendfile = no
in your global section

 > socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

Setting buffer to 8192 usually decreases buffer space on most systems. 
This maybe is a leftover in the docs from old times and not useful any more.
