Hi,
the man page of corosync.conf gives :
"Active replication offers slightly lower latency from transmit to
delivery in faulty network environments but with less performance.
Passive replication may nearly double the speed of the totem protocol
if the protocol doesn’t become cpu bound"
OK but knowing that, could someone give the pro & cons for passive
mode, and the pro & cons for active mode,
and/or how must we choose the real better mode for a HA cluster ?
If you care about latency use active, if you care about throughput, use
passive. From a functional perspective they both deliver the same
functionality. I have seen on this list that something with active may
be broken atm though, best to check with Jan Friesse.

Thanks a lot
