A Look At Windows Server 2008

SMB 2.0 – Copying Files Faster

Whenever files are copied between Windows systems, the SMB protocol (short for Sever Message Block) is used. Version 1 of this protocol, which is still in use today, was developed 15 years ago and introduced with Windows 3.11 for Workgroups. Since the fastest networks in use at the time generally offered a maximum transfer rate of 10 Mbit/s, the protocol is quite a bit out of date today. Indeed, with Gigabit Ethernet interfaces a common feature even on budget motherboards, SMB can’t keep up with current network speeds.

In specifying and creating version 2.0 of SMB, Microsoft has brought the protocol up to date. Among its benefits are that it can combine several requests in one data packet, meaning that more requests can be sent using fewer packets. Effectively, this reduces the overhead and consequently improves data throughput. Besides, more connections can be kept alive simultaneously, which in turn means more files can be open at the same time, improving the quality of the connection.

In order for the protocol to be used, both the server and the client need to support SMP 2.0. Windows Vista already uses SMB 2.0 and can thus benefit from the higher performance. The protocol is chosen automatically when a file transfer is initiated without requiring any additional settings by the user.
