In this article we will meet some of the most catastrophic ways to kill performance in a C++ program: returning objects by value. We will see why it is so slow, and how this can be mitigated. Still a few flaws to fix Before we get deeper into the example, however, we must add one…
In the second article we will confront performance issues caused by passing objects as parameters. A simple workhorse class Before we get into the actual examples we need to create a class we can use for our measurements and evaluations. For this purpose we create a “DynamicString” class which implements some sort of Python-like variable…
As an avid C++ supporter I frequently had to face several objections to the language, mostly based on its (supposed) performance issues. The two most frequent objections have been: C++ is too slow. Better stick to plain old C. C++ is not worth the effort. Java provides an easier environment and it’s almost as fast…
