The topic SMB tuning has been around for a while. I first noticed articles written by Michel Roth back in 2007 detailing the problems of using SMB 1.0 in a Terminal Servers and File Servers. Now, with the release of SMB 2.0 in new operating systems like Windows Server 2008, Vista, and Windows 7, the question comes up - "is SMB tuning necessary anymore?". Well, Dan Allen wrote an excellent article detailing everything you ever wanted to know about SMB tuning in heterogeneous and mixed environments. Dan gets very detailed on the analysis of SMB performance using Wireshark to capture packets and point out bottlenecks. This article is a must read!
