I posted our latest test results yesterday:
The Volano Report
http://www.volano.com/report.html
Thank you, Blackdown, for keeping green threads alive and working
extraordinarily well on Linux! Sun abandoned their "sunwjit" back in
1999:
java.lang.StackOverflowError with sunwjit
http://developer.java.sun.com/developer/bugParade/bugs/4299454.html
"The sunwjit has been obsolete for long time. We are not going
to fix the problem."
and now they've abandoned the Classic VM:
Classic VM goes into hard run at 1018 socket connections
http://developer.java.sun.com/developer/bugParade/bugs/4427986.html
"As to classic VM hang, it's a known problem. Since we are near
ladybird FCS and merlin does not include classic VM. This bug will
not be fixed."
Blackdown's Java VM using green threads on Linux is the only hope for
pure Java servers with lots of connections -- at least while we're
waiting for the Java 1.4 "new I/O" (or a different Linux threading
model).
By the way, I tested several just-in-time compilers with Blackdown on
Linux, and I'm very impressed with OpenJIT:
OpenJIT: A Reflective JIT Compiler for Java
http://www.openjit.org/
I tried OpenJIT, javacomp (Borland), shuJIT, sunwjit (Sun), and tya.
OpenJIT was the fastest in my VolanoMark tests and seemed to be the most
stable.
Thanks,
John Neffenger
