[zeromq-dev] Delayed Reception of messages when using Multicast Method (Using PGM)

When I tried the same with 10-20 messages I did not notice any delay or
problems. But with a large number of messages (>100) being exchanged there
is delay in the region of 20s or more!!!

Is this an inherent flaw in zeromq/pgm ? Is there anyway to workaround this?

Thanks.
