I'm using the tap adapter, bridged by WinXP with my network card.

Not sure about that (I made no tests), but it seems the tap-win32 
adapter is somewhat faster and reliable than the bridged adapter. Also, 
the code was revised lately to accomodate larger packets transfers.

I made some basic tests to measure the network performance. This tests 
are not reliable, just a simple timed copy between systems of a 34 MB file.

Using samba:

lan --> colinux : ~2.0 MB/s
colinux --> lan : ~1.5 MB/s
xp --> colinux  : ~0.5 MB/s
colinux <-- xp  : (didn't had a easy way of testing this)
lan <--> xp     : ~3.3 MB/s

Using nfsd/portmap on my router:

lan --> colinux : ~2.5 MB/s

I started nfsd with default parameters (sync), in a Gentoo machine, just 
for this test.
