How to reorder the code to improve the performance

Is your application huge ? A couple of tens of megabytes executables and shared objects ? Then I bet your application would benefit from the code reordering (or sometimes called the instruction cache optimization). A new article posted at developers.sun.com has a very graphical illustration of the effect of the code reordering and how to use the compiler to do that. Sun's top ISVs use those options to build their applications. And chances are, your application may benefit as well.
