I've sent 59 msg/sec (50 + 5 + 2 + 1 + 1) one day through emi2, with no
problem
at all (well, except that I had checking malloc and if I don't limit the
http connections,
store.lock would grow and crash kannel, but I didn't had time to recompile
kannel
with malloc=native)

I guess I had some luck that day (for the 50 msg/sec) or else too less time
to send the
messages in time (210k in almost 1 hour)
