kata-irc-bot<xu> I got some internal fio benchmark data, it shows virtio-fs (none+dax) 70-90% better than 9pfs (none or mmap)07:39
kata-irc-bot<xu> and about 80% performance of the ext4fs on host07:40

kata-irc-bot<graham.whaley> @aprice I think some numbers were posted with the original RFC and code by @davidgiluk and @stefanha as well - let me see if I can find a link...08:24
kata-irc-bot<graham.whaley> Could not find any numbers on the [web page](https://virtio-fs.gitlab.io/) - maybe they were posted in the first announcement (mailing list) and/or on the first Issue/PRs to kata...08:26
kata-irc-bot<graham.whaley> @aprice - asked @davidgiluk over on the kata-dev list - numbers were posted with the original kernel patchset submission - see in the big comment/description section at https://lwn.net/ml/linux-fsdevel/20181210171318.16998-1-vgoyal@redhat.com/08:38
