Slow CIFS/SMB speeds on OS X Mavericks (10.9)

Lots of complaints about how slow accessing Windows/Samba shares via Mavericks.  I've tried a couple of different things, but only found one that seems to restore SMB to a semblance of its former speed.  Thankfully its really easy.

In 'Connect to Server' when you specify the server by: smb://servername/share, instead do this: smb://servername:139/share

While I've not tried to analyze a network trace, I suspect that forcing the port bypasses some sort of smb version negotiation process.  But that's just a guess.
