Note that testing tools, especially Microsoft's tttcp tool are for networking testing not actual expected performance of real world applications. Windows performs best when you load up a few large messages not rapidly firing many small packets, but you are also fighting against the smaller schedular quantum of the desktop OS compared with the server editions.
Note that the TCP stack has been rewritten twice since XP was first released for both 2008 and 2008 R2 so you indeed might be able to find suitable registry settings to aid performance levels. -- Steve-o
