11MB/sec sounds like a saturated 100Mbit network connection. The fact the the 2 PCs are able to achieve more suggests that the network connection between them is 1000Mbit all the way.
I would suggest you have a close look at all the network interfaces between you and the SAMBA server. It's likely one of them is 100Mbit
