hi, they changed a lot of the threading/vm stuff with the release of kernel 2.4. i don't remember exactly the kernel-version for redhat 6.2 but i'm sure it is a 2.2 at maximum. but i would also be interested in a comparision linux <-> freebsd. jdk 1.3 is now officially supported under freebsd too. someone's got any numbers here? jan - -- Jan Heise / Tel. +49-163-4803237 / [EMAIL PROTECTED] - -----Ursprüngliche Nachricht----- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]Im Auftrag von josete Gesendet: Donnerstag, 7. Februar 2002 20:58 An: Orion-Interest Betreff: Re: Orion+Linux under heavy load Wich problem do you say they've fixed? threads under linux? i've done some tests with a redhat 6.2.(sorry i can't remember exactly the kernel version) and jboss, and only at start time it was about three times slower than the same jboss in a windows 2000. If with the new kernel versions it runs more efficiently, it would be great because i'm a linux fan that has been forced to use windows by this problem...
