GAMMA seems to be stable these days. We have run
succesfully with a version two versions before
the current one. Before that there were indeed
problems but they seem to have been fixed.
Could be interesting to ask the author of GAMMA to
see why he didn't use netpoll/mmap_ring (no idea
what they are I'm afraid) and whether it would be
I'd be certainly interested in a protocol which is
less intrusive than GAMMA.
