public class StringBuffer
extends Plugin
extends Plugin

This CFC greatly increases the speed of string concatenation. CF strings are immutable. When you append a string to another string, a whole new string is created. This is fine for a small number of iterations but painfully slow and memory intensive for a large number of concatenation operations. This plugin switches between StringBuilder and StringBuffer if running under cf8
