For one of our projects (server-side Java) we're using an Oracle database and
Weblogic drivers. As part of this we are required to run
with native threads (Ultra Sparc, dual processor, Solaris 2.5.1 with the
appropriate patches).

What we have noticed, while running a performance test on the server, is that
native threads are slower than green threads.

We noticed that JDK 1.1.4 from JavaSoft is MUCH slower with Native Threads, the
pre-release JVM JIT with native threads from SunSoft is a bit faster.

Luckily JDK 1.2 usign native threads is even faster (4x) than these JVMs,
however while running in native threads mode it is still slower than green
threads...

which isn't good when you want to scale a server-side Java app across
multiple processors.
