[jboss-dev] Differrences in CC runs for the AS testsuite

The exact same CC run for jboss-4.2-testsuite-sun-1.5 with close to zero code changes, took at different times: http://cruisecontrol.jboss.com/cc/buildresults/jboss-4.2-testsuite-sun-1.... 171 minutes 32 seconds http://cruisecontrol.jboss.com/cc/buildresults/jboss-4.2-testsuite-sun-1.... 159 minutes 47 seconds http://cruisecontrol.jboss.com/cc/buildresults/jboss-4.2-testsuite-sun-1.... 227 minutes 51 seconds So the slowest run took 42% more time than the fastest run. Obviously this has an impact in all time sensitive tests. Is the CC machine loaded with other stuff? What else could explain the time differences?
