Hi,
I recently tried to figure out the best and easiest ways to increase block I/O
performances with qemu. Not being a qemu expert, I expected to find a few
optimization tricks. Much to my surprise, it appears that there are many
significant improvements being worked on. This is excellent news :-)
However, I'm not sure I understand how they all fit together. It's probably
quite obvious from the developer point of view but I would very much appreciate
an overview of how dataplane, vhost-blk, ELVIS etc. should be used or developed
to maximize I/O performances. Are there documents I should read ? If not, would
someone be willing to share bits of wisdom ?
I've been using qemu for a long time and I'm very happy about it. Thanks to all
the developers :-)
Cheers
