Precompiled Stylesheets Memory-Usage during Runtime

[Robert Zimmermann <rz...@webde-ag.de>]

Hello,

I do not know the entire Xalan-C API, so I hope someone can help me here:

Is there a way to get information - during run-time - about memory-usage of
precompiled stylesheets?

Our application uses precompiled stylesheets a lot.
Some instances of them run into memory problems, not only but as a
consequence of extensive, sometimes mindless precompiling of any stylesheet.

The knowledge of memory consumption per stylesheet would help a lot to
improve the runtime behavior of our applications.


thanks in advance,
 Robert

I do not know any Xalan-C function to retrieve the memory usage of a 
compiled stylesheet, but we had a similar problem. We decided to use 
Xalan-C 1.7 (be careful because of bugs in Xerces-C 2.4) to reduce the 
runtime memory usage. Our application uses one "big" (~110kB) compiled 
stylesheet and the new Xalan-C saves 5-10MB (measured with the taskmgr ;^) 
compared to Xalan-C 1.3.
