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.
