OK, this is not a benchmark, and probably not even worth considering a
real timing, because there are a lot of different varaibles that have not
been contrained enough. I just wanted to hear a first impression. Is this
already known? May I have done something completly wrong, etc...
Here it comes:
I did a small timing on a bean developed with Percolator
(http://www.percolator.org) on three different EJB servers: jboss, jonas
and Weblogic 5.1. It is a rather small entity bean and the test was done
from one client only. First it creates 1000 entitys, then it looks up each
entity (in percolator mening getting all the data over in a value holder),
then it just lookes up the same entity 1000 times.
The result? For weblogic this took about 50ms for each operation. Creating
a bean took 50ms, looking it up 49ms. With jonas, this took about 2-3
times longer. (184ms to create, 169ms to look up each and 128ms to lookup
one several times). But with jboss, this took a lot longer. It took about
15 times longer to create a bean compared to WLS5.1, and about 7-8 times
longer to lookup a bean.
I have to admit, they was not even run on the same JVM, WLS was Sun 1.2.2
for Linux and Jonas 1.3 for Linux (and I could not find a way to turn of
all the logging in jboss), but it still sees to be a to huge different to
really be only about runtime differenses, or am I wrong? Is there a way to
speed up jboss? Or is this low performance a known problem?
Hope you don't take me wrong. I would really like to see jboss beeing one
of the performance leader (it will make it a lot easier to recommend it
then).

Peter
