Speed up coldfusion applications

The most important when you write a web application is that it's error free and that it's fast.

I will give you a few tips how you can speed up a coldfusion webapplication.

When programming:

1. Keep the coldfusion web application small, which means that you should use often cfinclude. Coldfusion reads many small applications gathered together much faster then one big application.
2. Use cffile instead of cfhttp when possible.
3. Reduce database access, use cachedwithin whenever possible.
4. When you need a file more then once using cffile, save the file as a application variable.
   <cfparam name="Application.xmlexpire" default="#Now()#">
   <cfif DateCompare(Now(), Application.xmlexpire) gte 0>
   <cffile action="read" file="/home/xml/xmlfile.xml" variable="xmlvar">
   <cfscript>
   Application.xmlfile = XMLParse(xmlvar);
   Application.xmlexpire = DateAdd("d",1,Now());
   </cfscript>
   </cfif>
   <cfset xml = Application.xmlfile>
