My understanding is that native threads were not dependent on kernel threads; that is, native threads are there to, among other things, reduce I/O overhead. I understand as much to know that to go SMP inside of the Java VM requires kernel threads. But again, the way I understand it is that by talking to a VM built around pthreads, that some performance gains can be had. So I guess that (until SMPng becomes a reality) what I'm asking is whether a native VM build exists around pthreads. -- Dylan Carlson (absinthe@pobox.com) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-java" in the body of the message
