I tried to include the newly announced "vhost" driver (Michael Tsirkin) for virtio acceleration, but ran into issues getting the patches to apply= =2E For now, this includes native, virtio-u (virtio-userspace), and venet all running on 31-rc4. If I can resolve the issue with Michaels patches, I will add "virtio-k" (virtio-kernel) to the mix as well. For now, here are the results for 1500mtu: native: 7388Mb/s, 29.8us rtt (33505 tps udp-rr) venet: 3654Mb/s, 56.8us rtt (17600 tps udp-rr) virtio-u: 1955Mb/s, 4016.0us rtt ( 249 tps udp-rr) Note that on one particular boot-session, I actually saw venet run consistently 4600Mb/s, and virtio-u run consistently 2800Mb/s. I am not sure why other runs resulted in deterministically lower numbers, but I included the average of the low runs to be conservative, ~3600, ~1900 respectively). Of interest here is that native made a huge jump (2.6.29 was more like 4Gb/s), and also that KVM regressed a bit, especially compared to native numbers. The cause for either of these changes is not known at this time, but I will investigate the cause over the next few days. In any case, I have updated the graphs on the AlacrityVM wiki to reflect these latest numbers: http://developer.novell.com/wiki/index.php/AlacrityVM Kind Regards, -Greg --------------enig965E8CB54FAEC0A7B24CCFC8 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.11 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkqDKWsACgkQP5K2CMvXmqHOhgCfWd6BYp0Waa95XAhrQf1NqhBm 2EEAnj2/0Fngi3pu7fa3sbRxirTQd/+D =7ezu -----END PGP SIGNATURE----- --------------enig965E8CB54FAEC0A7B24CCFC8--
