Best way to learn how to write latency-critical, fast C++/Java/C# code?
<p>Could anyone give me some pointers as to the best way in which to learn how to do very low latency programming? I have many programming books but I've never seen one which focused (or helped) on writing extremely fast code. Or are books not the best way forward?</p>

<p>Some advice from an expert would be really appreciated!</p>

<p>EDIT: I think I'm referring more to CPU/Memory bound.</p>
