You should grab yourself a load tester, like the one at
www.pureit.se/pureload and see for
yourself.
In tests I have made ASP's have never outperformed Servlets. For simple
things like just
sending HTML back to the client Servlets are faster.
With equivalent DB requests ASP's and servlets tend to perform similarly
well although I never
managed to get an ASP within 10% of the equiv servlet's performance.
Flexibility is everything. There are so many things you can do directly in
Java that you can't in ASP VB
or JScript that even if the performance of servlets was worse (and it isn't)
then servlets would be a step
up.
One area where Servlets win out is footprint. ASP's need to be interpreted
each time they are run, each request
is handled as a separate process. VB is not a very efficient language for
this to work efficiently.
Servlets have a small code size, each one sits there as one instance
(SingleThreadModel aside) and modern
JIT's give you nearly the performance of native code in a lot of instances.
Well written servlets tend to run ok whereever they live. I have tested
servlets written with Symantec Cafe under NT
using the servlet runner, then deployed them to JRun running behind IIS on
NT with no pain at all.
I then deployed them to JRun behind an Apache server running on NT, no pain,
Apache with JRun on Linux no pain,
Apache with JServ on Linux again no pain. These servlets are production
servlets and not simple ones destined for the
scrap heap. Try that with any ASP.
Just a question, has anyone ever tried to chain ASP's together?
Hope that helps
Andy Bailey
PS I have developed web apps using both ASP's and Servlet/JSP's and as far
as I am concerned there is no comparison
in the end
