Well, Xen implementation has the grant tables and all their ring code (a good one thought). On the beginning you can start without convergence and aim towards it. Here is a link that describes Xen HVM pv driver performance: http://www.xensource.com/files/summit_3/xen-pv-drivers.pdf for 1500 mtu their doing 400Mbs rx, 500+Mbs tx. I guess Ingo will soon reach that... > >Patches? >Rusty. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
