We are pleased to announce the availability of the latest networking benchmark numbers for AlacrityVM. We've made several tweaks to the original v0.1 release to improve performance. The most notable is a switch from get_user_pages to switch_mm+copy_[to/from]_user thanks to a review suggestion from Michael Tsirkin (as well as his patch to implement it). This change alone accounted for freeing up an additional 1.2Gbps, which is over 25% improvement from v0.1. The previous numbers were 4560Gbps before the change, and 5708Gbps after (for 1500mtu over 10GE). This moves us ever closer to the goal of native performance under virtualization. These changes will be incorporated into the upcoming v0.2 release. For more details, please visit our project wiki: http://developer.novell.com/wiki/index.php/AlacrityVM Kind Regards, -Greg
