[FX.php List] Performance issues with FM's xml interface

First, as for FileMaker, I've worked on several projects where we  
EXPECTED 7 to be faster than 6, and it in fact was not.  That is  
another issue/debate, but when building solutions via XML (FX.php)  
for the web, I always take the following steps:

- create a separate layout for anything that is called via XML.
- only place pertinent, necessary fields in the layout.  related  
fields are fine, but use only what you need...  you want it  
practically naked, it's so spartan.
     (* remember, if you have related fields that are not always a  
'valid' relationship, place them in portals)
- summary fields slow things down, as well as anything that slows  
down FMP.  It's hard if you have a primarily FMP client based  
solution, but I usually try to do all logic, calculations, etc within  
PHP.  When it comes to the web, it helps to think of FMP as a place  
to store data whenever you can.  I start that way, then add the  
necessary FMP functionality.
