Hi,

This is a little off-topic but I thought I'd do a quick poll. I've
got an opportunity to reconfigure my multi-server Tomcat/Java setup
for a computation-heavy webapp. One vendor is proposing dual process
Woodcrest (dual core) 2.0 GHz, the other is promoting dual Xeon
3.2GHz. The Woodcrest's have slower clock speeds but the dual core is
supposed to make it faster.

Just curious if anyone has experience with the Woodcrest servers - in
particular if anyone has benchmarked Sun's JDK on the two processors
with a computation heavy app I'd love to hear from them. (Can Sun's
JDK make effective use of the multi-processor, multi-core system?)

Cheers, WILL

Full disclosure, I work for Intel. :)

First, are you sure it's a 2GHz Woodcrest? I thought it would be a 3GHz
part.

Second, is it two Woodcrest (for 4 cores total) or just 1 Woodcrest?

Third, "woodcrest" is an internal code name, and the parts are sold
under the Xeon brand, so which Xeon is a question you want to ask the
vendor - it could be woodcrest based as well.

Finally, the current world record in spec's JBB2005 benchmark is held by
IBM with their JVM on woodcrest (Xeon 5160) at 114k bops/JVM on a 4 core
machine...

You can go see the results here :

Thanks, Geir,

Yes, I'm comparing two Woodcrest chips (4 cores total) with 2
single-core Xeon chips. I'll check the specs again -- good comments.

Someone recommended this Wiki article, I really liked it.
http://en.wikipedia.org/wiki/Intel_Xeon

That's pretty cool about the benchmark.

IIRC the single core xeons are the old architecture, and really suck
(speed, heat and cost) compared to the new "core" architecture.
