Apache is not multithreaded, AFAIK. Instead it runs multiple
processes, each process handles one request at a time.
iPlanet webserver will probrbaly be faster if it is truly
multithreaded (I am not sure).
However, if you do any meaningful testing, you will be bound
by the java servlets you run. In this case, webserver performance
becomes irrelevant, and the question becomes:
is iPlanet's servlet engine faster than JServ?
In both situations, a natively multithreading JDK could prove
the deciding factor. I believe iPlanet does use a natively
threaded JDK (I don't see why they wouldn't). Just make sure
to give JServ the same chance. Make sure you use the best
JVM for JServ. That, if you are using jdk1.1, would be IBM's
jdk1.1.8. If you are using jdk1.2, I am not sure which is the
best JVM.
If the JVMs for both JServ and iPlanet are more or less equal,
then the question truly becomes:
is iPlanet's servlet engine faster than JServ?
I would be interested in the answer you get. I am betting they
will be pretty closely matched.
Also keep in mind this info:
In a real world application that does database transactions,
performance tends to be database bound. That gives us 2 points:
1) The performance of iPlanet vs. JServ is irrelevant if you
have a database bound application
2) If you still want to compare the 2, make sure they both
connect to the same database server.
OR
make sure your benchmark servlets do not depend on the database
at all.
Let us know what you find out.
