This statement arouses my curiosity. It seems that because you can "tweak the Linux level" (meaning: tweak the underlying OS libraries and kernel), one would want to test java (compiler and JVM) on this platform. As part of a test suite, you could try and hinder the performance of a JVM by modifying compiler flags and kernel parameters. On the same token, you could try and maximize the performance (for various goals) of a JVM by different modifications. Then, with these results, a sort of performance matrix could be created showing the particular kernel parameters against various performance goals (such as flops, or graphics, or EE beans, or servlet load, etc). I am not suggesting Sun should do this work, but I am suggesting that Gentoo seems to be an ideal platform (on any/all supported hardware) to "tune" java to maximum performance, depending on one's goals. -gnul -- gentoo-java@gentoo.org mailing list
