[Qemu-devel] Fastest TCP/IP Stack

[Joseph Miller]

I'm running a terminal server under qemu with kqemu compiled into my kernel 
under the -kernel-kqemu for fastest performance.  What is the most efficient 
method of -net ?  I was using -net user with OpenVPN to connect to my 
internal LAN, but I have switched to -net tap to see if that is faster.  Does 
anyone have any knowledge of which would take the least overhead?  I noticed 
on my top stats that my % sys was particularly high when using networking 
under -net user.  Thanks
