There has been a lot of work done in the past to make this happen.
Drop me an email if you'd like to hear more about the boring story of
threading support within JVM ;-)

No, that's not true. Both JDK 1.4.1 and 1.4.2 from Sun support NPTL.
Well that certainly is good news.
I am currently still stuck with RH 7.2 ( grin! ) and would like to move
to RH9 ... but thought I could not yet because the JVMs would have to
support NPTL.

Hi Juergen,
I'm not if anyone working on the blackdown project is planning to
get support for NPTL in ahead of Sun or IBM.
It already works.
Do you mean that the Sun and Blackdown native-thread HotSpot Server VMs
will be able to go right up to 10,000 connections (about 20,000 threads)
right out

Yes (our AMD64 version will be ready for our 1.4.2 release) but, of
course, you can't make assumptions about the performance differences
between 32-bit and 64-b

Hi Bill,
Also, 2.5.x Linux has changes to their 1:1 model that greatly increases
scalability for dealing with a large number of threads.
I was under the impression that Java application developers will have to
wait for the Java virtual machines to take advantage of those threading
changes before
Ciao Marco,
- you tested Blackdown-1.3.1 using green threads, but Sun JVM used
native threads. In Linux this makes a huge difference in terms of thread
scalability with one CPU. It should be useful to show the Linux Sun
1.3.1 JVM results with -green option.
That's an easy test result to add. :)
