We evalutated Jonas, Weblogic and a JSP only scenario.
The test was 3 or 4 jsp just asking some data to some Session Stateless EJB.
These were connected to an Oracle instance running in another server.
We tested it in NT, Linux and HP-AUX.
We tested it using 10, 20 and 40 thread each one asking one jsp page at a
distance of 3 seconds between each request.
We used Apache 1.3.9 with JServ 1.0 and gnujsp 1.0 for JonAS, the integrated
web server of weblogic.
Jdk was 1.1 because was the only one avaiable on HP-AUX 10.20.
Our machine was a Pentium II with 128 M RAM, 1 processor.
I can't report the results in full because I don't have them in electronic
format yet, but in synthesis:
Times are in milliseconds, cl stands for clients:
Weblogic response time was: 123 with 10 cl, 150 with 20 cl, 220 with 40 cl,
650 with 60 cl
JonAs 1.4.1 was: 725 with 10cl, 1200 with 20 cl, 4000 with 40 cl.
Using normal Java classes without them being in a EJB container: 327 with 10
cl, 370 with 20 cl, 660 with 60 cl, 1900 with 60 cl.
The last row is probably because of the poor implementation of Apache on NT,
on Linux and HP-AUX Response time are the same as Weblogic until we get to
40 cl then they start to fall.
This was on NT machines, performance on Linux and HP-AUX was a bit worse.
The problem was all about %CPU , Jonas with only 20 cl takes 100% of CPU
time.
Profiling the application we saw that the problem was all in the RMI part,
so essentially in the data passing
between JServ and JonAS. When we used an EJB calling another one things got
worse then that, because there was more marshaling going on.
We think that an integration with some web-server can make the situation
better.
This is only an our supposition, of course.
