So, another post without code…- -

Part I covers different aspects of programming. And Part II is going to focus on one area: performance. Column 6 is the first chapter and it gives a case where a certain program (movement simulation in gravitational situation) can be speed up by 400 times. This is achieved by optimizing at different levels: algorithm, data structure, code tuning, data structure tuning, hardware upgrading, etc. So as program or IT solution is multi-level thing, performance optimizations are multi-level too.
