Yea. Funnily enough I wrote a library in ef_vi for UDP sending with mixed results. Just UDP/MC dispatch and it was a little like grappling with an underdeveloped library. Pretty fast but I'm sure I hit some kind of memory barrier bug at one point.

The thing with onload is the sheer simplicity which makes it an easy sell. Also handy to tweak socket options with env vars. They also have a direct tcp lib if you need a some extra nanos. Templates sends too.

Not heard of netronome and never used libexanic.

These approaches mean you have to invest more in external passive monitoring tools as is stats are of little help.
