Based on our experiences with virtio-net, what I'd suggest is to make
a lot of tunable options (ring size, various tx mitigation schemes,
timeout durations, etc) and then we can do some deep performance
studies to see how things interact with each other.
I think we should do that before making any changes because I'm
deeply concerned that we'll introduce significant performance
regressions.
I agree. We can start with this patch, with a tunable depth,
defaulting to current behaviour.
I wouldn't be opposed to that provided we made it clear that these
options were not supported long term. I don't want management tools
(like libvirt) to start relying on them.
