David:
I have done a lot of testing with this exact setup. Here is what we've
found:
1. The older IBM JDK 116 JVM had a severe socket bug which prevented high
connection rates.
2. As of the refresh of the site on 8/21/99 this bug has been fixed.
3. The IBM JDK supports native threads on multiple CPU boxes and this works,
though we did not see nearly linear speed up on CPU limited tasks
4. Our servlet had a stable memory footprint on the Blackdown 117v3/TYA1.4,
but the memory footprint grew unbounded with the IBM JVM. Due to the size
of our servlet, we did not have a chance to trace whether this was GC or
some other similar problem.
5. The performance of the Blackdown/TYA combo was within 10% of the IBM JDK
for our application.
If you have a multiple CPU server, then this is the only JVM on Linux we
have seen support native threading without bugs in the threading. I would
still put this at the experiment level and not at the production level.
