Re: [xsl] Optimization Question

All,

   thanks for all the help. My lookup document (~5MB) is static.  If I 
were to do an xsl:include as opposed to me using a document call, would 
using the compilier help?  Is there someting I'm forgetting?

I'm asked occasionally whether I plan to do a Saxon compiler - more

strictly, a bytecode generator. At present, I don't: I think it would 
slow

down the rate of progress on the product considerably, if only 
because code

generators are notoriously hard to debug. I prefer to spend the 
effort on

improving the query execution strategies, which can produce much bigger

potential savings. In any case, I think that for most people memory 
is more

of a constraint than processing speed.




I think this is a good idea. I usually run my app with Saxon and Xalan 
interpretive(?). I occasioanlly run it also with XSLTC and Resin's 
compiling processor (which requires much less memory and is the 
fastest). I really wish I could use a compiling processor (especially 
resin), but I always fallback to Saxon (its small and fast enough) 
because it just works and there is always some little problem I run 
into with compiling processors.



best,
-Rob
