Socket performance

Just written a small script to test network/firewall performance in Python, and could not help myself from testing it on both XP and Linux...

OpenSUSE 10.2 performance:
1896.296296 mbit / second

Windows XP performance:
299.645137 mbit / second

(Tested on a dualboot machine.)

So, again the question must be, is this related to Python or the OS?

Well, iperf to localhost on Win XP yields:

C:\Documents and Settings\Martin\Desktop>iperf.exe -c localhost

iperf on Linux:
