1-4-9, also tested with 1-4-8, the behaviour is the same. I used the
exact same libevent in all the tests (exhibiting latency or not) so I
tend to rule out libevent.

Yes:
server on suse 9 , client on suse 9: there is latency
server on suse 9, client on latest ubuntu: no latency
server on ubunutu, client on suse 9: latency
all on ubuntu: no latency
The very strange thing is that is only occurs when using the binary
protocol, ascii one is working perfectly in every configuration.
Is there really that much of a difference in network exchange patterns
between ascii and binary ?
