Hi,
I am on the ECperf 1.1 JSR expert group, representing Macromedia. Since all
the vendors participating in the JSR have yet to release any official
numbers, it's tough for some of us (even on the expert group) to know what
constitutes good ECperf results. There's a somewhat vicious circle of
tuning and testing while hoping/fearing someone else will release their
numbers first.
To make a long story short, I set up ECperf with JRun 3.1, then with Sun's
1.2.1 RI, then with JBoss 2.4-Tomcat-3.2.3 beta. Much of this work was
started by Bill Kayser of StepZero, who contracted for Macromedia doing a
lot of performance-related work. Bill worked up the Ant scripts and JRun
deployment descriptors that are in the ECperf kit on your Web site. I've
since worked out the kinks for JRun deployment and configuration, and
applied that experience to the RI and JBoss.
Since JBoss is not a J2EE licensee, it cannot publish offical, reviewed
ECperf numbers. Reporting stipulations in the ECperf spec and on various
third party software you'd probably want to use in a benchmark (viz., an
Oracle d.b.), further make it unlikely JBoss would gain the required third
party approvals to publish "official" results. Regardless, anyone can
download ECperf and JBoss and try it out for themselves. (In fact, these
very points make me think maybe restrictions should be loosened for open
source implementations.)
Anyway, I've seen the ECperf page on the JBoss site. It's pretty sparse.
Why? What happened to the plan to have JBoss+ECperf up and running by the
stated date? It's definitely do-able with the current beta. But you'll
need a slew of bug fixes to the ECperf app itself, most of which you can
figure out through trial and error, and (hopefully) all of which you will
get when ECperf 1.0 first bug fix patch comes out in the next month or so.
Is anyone else here working on JBoss and ECperf? I have some stuff you
might find very handy. I'd also be interested in feedback on how to better
tune JBoss for ECperf. If you need someone to write some doco on it, I'd be
glad to, along with JBoss-specific scripts and deployment descriptors.
