Optimizing C++ Singleton Performance: Best Practices and Implementation Guidance
By
jandeboevrie
A good honest bake. Not flashy, but you'll finish the whole bagel.
Summary
This article focuses on optimizing C++ singleton implementations for performance, using a display manager example from the Linux world (like GDM or LightDM). The author builds on a previous post about correct singleton implementation and now adds performance considerations, providing guidance on choosing the best implementation approach for specific use cases.

· 3 pulledIn my January post, I focused on implementing a singleton correctly. This time I want to add performance into the mix and show you the best way to implement your singleton... or give you guidance to pick your best way.
I'm using a display manager as an example, like GDM, LightDM, or others in the Linux world.
Let me quickly go through the various parts. In A, you see the data type Resolution which illustrates two resolutions; you can imagine the rest. Next in B, you find the DisplayManager implementation.
