Hello Neil,
I cannot speak specifically for Websphere but using JSP for the output will
generally be alot faster than using a Servlet with out.print statements (partially
due to the fact that the output from the JSP can be outputted as one byte[] with
only the dynamic part of your information actually being dynamically generated).
Also, a JSP is only compiled once, not at every request, so that is not a
performance problem.
<vendor>
In Orion Application Server (http://www.orionserver.com) the JSP engine is
extremely optimized. Many optmizations can be done in JSP since they're more
abstract. In a Servlet it is harder to do certain optimizations since the developer
usually use lower-lever constructs that cannot easily be optimized by the
container.
