I've not done any benchmarks, but I do pay attention to resource
usage. (Host OS linux) -net user has pretty good thoughput, but does
burn some cpu. I think in that regard, -net tap has less overhead.
During my use of qemu, I've noticed that the quality of the nic driver
and the nic emulation itself comes into play. I would try the
differnet models and see. -net nic,model=pcnet always seemed like it
performed well. YOMV.

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
