Summary

ColdFusion code can execute very efficiently or run very poorly, depending on how you write the code. You can use a number of techniques to write code that will perform optimally. For example, you can identify effective ColdFusion coding techniques, avoid having ColdFusion do the database's job, enforce strict attribute validation, and use <cfcache> when logical. To be sure that a particular technique has actually increased performance, you can use a number of ColdFusion tools, such as the <cftimer> tag and GetTickCount() function, to show processing time.
