Good question. I should probably add it to the documentation as a clarifier on the optimization process.
Most of our development happens on Windows 2000 so we use the Sun JDK libaries with Jikes for compilation of our own code. However, for the optimization testing of JBoss, we used the Sun JDK 1.4.1_01 compiler (as Jikes can't handle optimizations and IBM have not released a SDK 1.4.0 for Windows yet). Also, as the benchmark JDK reference, we thought it fair to use Sun's compiler to perform the JBoss build. So we were surprised with the results in terms of memory space though not so much with the speed as we know that IBM are pretty good with engineering their SDK/JVM. > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Sacha > Labourey > Sent: Thursday, 19 June 2003 10:30 PM > To: [EMAIL PROTECTED] > Subject: RE: [JBoss-user] ECperf 1.1 Documentation and Driver/Launcher > modifications > > > BTW, for the perf.
