It could also give you an idea if it's time to upgrade your computer to more cores.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Start-up times may vary sligtly between different runs, due to system load, filesystem caching etc. We are interested in your best times <span> :) </span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>On with the showdown! Start JBoss AS 7 in standalone mode and add your results to this page. We are mostly interested in <strong>stock JVM settings</strong>, just to even the playing field.
