We are running 1.6 update 37. That was released on the same day as your
version, so it should have the same bug fixes. We use these options in
production, it is very stable:
export CATALINA_OPTS="$CATALINA_OPTS -d64"
export CATALINA_OPTS="$CATALINA_OPTS -Xms4096m -Xmx6144m"
export CATALINA_OPTS=
We are currently operating at reduced load which is why the ParNew
collections are not a problem. I don't know how long they were taking
before though. Thanks for the warning about index formats.
Our JVM is:
Java(TM) SE Runtime Environment (build 1.7.0_09-b05)
Java HotSpot(TM) 64-Bit Server VM (b
Several suggestions.
1. Adjust the traffic load for about 75% CPU. When you hit 100%, you are
already in an overload state and the variance of the response times goes way
up. You'll have very noisy benchmark data.
2. Do not force manual GCs during a benchmark.
3. Do not force merge (optimise).

Have you done a Java heap dump to see what the most common objects are?
