[Qemu-devel] Block I/O optimizations

[Loic Dachary]

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
