After having seen thread after thread on this list and others discussing code optimization for CF I am left with the following impression. People seem to be missing the forest for the trees.
Every idea/technique that has been suggested thus far for code optimization is a waste of time for almost all applications. Sure some of these ideas/techniques code save a few milliseconds here and there, but they offer very small gains in scalability. There are much simpler ways to achieve greater scalability in less time than code optimization e.g. caching. I suggest people spend their time seeking out these ways instead of spending time on code optimization. You should only spend time on code optimization after every other performance enhancement has been tried. Further, servers are so cheap these days that adding additional hardware tends to be far cheaper than developer time.
