Bela Ban commented on JGRP-394:
-------------------------------

UNICAST also uses the Retransmitter: Retransmitter needs optimization to avoid linear list iteration

> - NAKACK.handleMessage(): NakReceiver.add() --> Retransmitter.add() --> TimeScheduler.add() is quite costly; we also iterate through a linear 
> list when removing a message from the Retransmitter !
> - Bundler: sending is over-synchronized; use ConcurrentHashMap for msgs
> - GroupRequest and RequestCorrelator eat CPU cycles in MessageDispatcher: remove them ?
