Weblogic & Tomcat simple java loop performance varies -

have issue performance of simple loop (see code below in looptest.performtest) varies dramatically, consistent lifetime of process. for example, when run within weblogic/tomcat may achieve average of 3.5 billion iterations per second. re-start , may achieve 20 million iterations per second. remain consistent lifetime of process. when has been run directly command line, on every occasion, has run fast. this has been run under linux, windows, tomcat & weblogic. slow execution occurs more regularly in weblogic tomcat. test specifics the test code moves potential os calls (timing) before , after test, differing size loops should allow slow os calls apparent progressive apparent performance improvement loop size increases. the number of iterations performed test determined time (see runtest) rather being fixed due large variation in performance , more complex may expected. public static abstract class performancetest { private final string name; public performa...
