[infinispan-dev] Query integration tests performance and JGroups

[Gustavo Fernandes]

Hi,

While investigating some CI failures in query (timeouts), I've narrowed
down the issue to the Jgroups protocol stack being used. 
Running a 'mvn clean install' in the query/ module takes about 6min
(when timeout does not happen). If I run instead: 

mvn -Dtest.protocol.jgroups=udp clean install

Time goes down to around 50s. Recent changes in core's jgoups-tcp.xml
for the tests were the removal of the loopback=true and the modification
of the bundler_type, but they don't seem to affect the outcome.

FYI, taking a single test and stripping down from it everything but the
cluster formation and data population (5 objects) leads to the cpu
hotspot below, and it takes almost 1 minute  

I'd be happy to change the query tests to udp, but first would like to
hear your thoughts about this issue

Gustavo
