What is P-code?
P-Code is what CF compiles the templates into – if you have the templates cached then it reads them out of memory. If you turn on Trusted Cache, then it’ll never look for newer versions of the template, so it runs even faster. Put the Template Cache up (fairly) big, and let the server do what it has to. As a rule of thumb on template cache size, add together the total filesize of all your ColdFusion templates and multiply the answer by four. This give CF room for maneuvering and it should never have to remove items from cache.
