I know the pages that use template tags are slow the first time you hit them
because there are normally several jsps that need to get compiled. After
that I would think it would be the same performance-wise as a jsp that does
lots of jsp:includes. Has anyone tried to use struts-templates in
production? I am starting to use them for a bench project in order to guage
their value so I can't really speak to their performance.
Speaking of includes, the following sentence in the documentation is
misleading/wrong:
From /struts-documentation/building_view.html
The include directive (%@ include file="x" %) is processed when the
JSP page is compiled. It is useful when you are including HTML code that
will not need to change at request time. It treats the text being included
as static text, much like the #include directive in C or C++.
An %@ include file="x" % directive can include a file that contains
java code or jsp tags. The code in the included file can even reference
variables declared earlier in the outer jsp page. The code is inlined into
the other jsp before it is compiled so it can definately contain more than
just HTML.

The template tags in the Struts library seem a bit pokey, but there's a
lot going on there (reads one file, then merges from another). I don't
think alot of applications actually use these tags much.
I believe that any JSP is suppose to compile down to a single servlet
class file. The custom tags are just alternate ways to call
subroutines.
If you check your work directory, you'll see that a number of automatic
Java files might be generated for a given JSP, but they resolve to a
single class.
Struts is also fine with distributing precompiled JSPs, which can
eliminate the cycles it takes the container to check to see if the JSP
needs to be recompiled.

Hi
What do you think is the over-head in using struts
tags in terms of performance? ( all tags in general )
And let us say we use a template for a page which has
a header, a side bar, a footer, a content. Each of
this gets commpiled into a class and thus a single
page is converted into a set of classes ( r these a
set of servlets )? Doesnt it slowdown when compared to
a single servlet just outputting the stuff???
Thanks
