Bela Ban commented on JGRP-267:
-------------------------------

when we instrument the channel.send() method so see how long a send() takes, we get the results below. Most of the time, send() takes almost no time, but sometimes it takes 15ms !
Need to investigate (e.g. with PERF) to see where that time is spent !

$ jt RoundTrip  -props ./tmp.xml -num 10

> #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
