[jboss-jira] [JBoss JIRA] Commented: (JGRP-267) RoundTrip is slow with bundling disabled

    [ http://jira.jboss.com/jira/browse/JGRP-267?page=comments#action_12340697 ] 
            
Bela Ban commented on JGRP-267:
-------------------------------

The problem occurs when sending small packets (size: 10 bytes) with DatagramSocket.send(): sometimes it takes 16ms for send() to return. The send buffer should *not* be the problem as it is big enough. When sending larger packets (e.g. 1000 bytes), the problem almost never occurs !
This needs to be further investigated once (if!) we have an APR-based transport, will move to 2.5 and add a dep to APR transport

> #1 Disable bundling in fc-fast-minimalthreads.xml: UDP.enable_bundling="false"
> #2 Run the server: jt RoundTrip -server -props ./fc-fast-minimalthreads.xml
> #3 Run the client: $ jt RoundTrip -props ./fc-fast-minimalthreads.xml -num 10
> The first time, the client runs okay, but when it is run multiple times, it always slows down halfway through a run
