Subject RE: Solr query performance tool

You have to be careful looking at the QTime's. They do not include garbage collection. I've
run into issues where QTime is short (cause it was), it just happened that the query came
in during a long garbage collection where everything was paused. So you can get into situations
where once the 15 second GC is done everything performs as expected! I'd make sure and have
an external querying tool and you can monitor GC times as well via JMX.

You can use this tool to analyze the logs..

We use solrmeter to test the performance / Stress testing.
