Yet another reason for Linux ....
Adding SP2 to WinXP will throttle your machine to 10 pending
simultaneous TCP connection attempts (10 TCP sockets in an open SYN
state). Anything more, and you will get the dreaded:
"EventID 4226: TCP/IP has reached the security limit imposed on the
number of concurrent TCP connect attempts"
Microsoft has done this in a broken attempt at throttling worms probing
random machines. There is no registry key to fix this (TcpNumConnections
limits your total number of TCP connections, not the number of pending
connection attempts).
The side effect of this: P2P clients are now greatly impacted
(effectively useless):

There is a binary patch you can make to your TCPIP.SYS file here:

One word: Unbelievable.
