#Keep it hot code
I wrote some simple collision detection code a while back and never got around to optimizing its performance because it was good enough as it was and I had greater worries elsewhere. Let me just tell you how this tutorial came about. And what does it mean to be "hot"? It means to be in high demand, as in the expression "a hot commodity". So, what should be kept hot? Values, memory and machine instructions.
#Keep it hot software
Well, software is about using memory and machine instructions to compute values. You might be wondering what it is exactly that is supposed to be kept hot. When I named this tutorial "Keep it Hot", I wasn't thinking about the Cameo song from the 80s, although you're welcome to listen to it while you read this tutorial, that is, if you agree with me that a funky beat is the real secret to producing good code!
#Keep it hot how to
If you expect this tutorial to be about showing bits of code and the assembly listings generated by the compiler and then, showing how to reduce the number of instructions using nifty tricks, then you are sorely mistaken about what has most impact on performance. This is going to be a step-by-step journey through a real example, with real benchmark results at every step so that you can see the effect of the different optimization techniques.Īnd as my first tutorial on performance optimization, I have to talk about the most important principle in performance optimization: keeping things hot. If you or someone else feels unwell with a high temperature during hot weather, it may be heat exhaustion or heatstroke.This tutorial is the first time I write about coding techniques for improving the performance of software. They can inspect a rented home for hazards to health, including excess heat.įind your local council (GOV.UK) Watch out for signs of heat-related illness You can also get help from the environmental health office at your local council, if you think a hot house is affecting your health or someone else's.

Electric fans can help if the temperature is below 35 degrees. Close windows during the day and open them at night when the temperature outside has gone down.
#Keep it hot skin
