Efficient C++ Performance Programming Techniques

Key Points

• Inlining can improve performance. The goal is to find a program's fast path and inline it, though inlining this path may not be trivial.

• Conditional inlining prevents inlining from occuring. This decreases compile-time and simplifies debug during the earlier phases of development.

• Selective inlining is a technique that inlines methods only in some places. It can offset some of the code size explosion potential of inlining a method by inlining method calls only on performance-critical paths.

• Recursive inlining is an ugly but effective technique for improving the performance of recursive methods.

• Care needs to be taken with local static variables.

• Inlining is aimed at call elimination. Be sure of the real cost of calls on your system before ...
