Is anyone out there getting Samba speeds better than these below w/ their Pogoplug Optware setup? (I hesitate to ask it in the wider non-Optware context {like w/ Debian} cuz its apples and oranges, difficult to compare)

I currently have the following rates (average over about 1 minute, Pogoplug & MacPro on Gb network):

• read :  19MB/sec
• write:  17MB/sec

I installed Optware in order to get Samba2 up and running on my Pogoplug (V3, POGO-P21).  It works well.  

Two articles that referred to:

• the NSLU2 site's : http://www.nslu2-linux.org/wiki/Optware/Samba2   (see Plug Addendum half way down the page)
• https://turriebuntu.wordpress.com/pogoplugdockstar-pages/add-samba-to-your-pogoplug/

In [global] of my smb.conf I have the option 

    socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE SO_RCVBUF=131072 SO_SNDBUF=131072 SO_KEEPALIVE
