I'm helping a friend setup some Xen instances and he's wanting to use LVM for his MySQL based domUs and I would like to use tap:aio instead. His concern is performance..

Is there any documentation out there that documents the rough performance penalty of using tap:aio? My search on the intertubes yielded nothing concrete on this topic.

thanks!

I'm getting to it... I'm starting to gather testing information to benchmark Xen and other VMs in various situations. LVM vs files is on the list. It probably won't be until September before I finish and publish the results though - sorry.
