Performance of Singleton Class Instance Method vs. Static Class Method in PHP?

Question

I\'m interested in objective analysis of which is more performant; calling instance methods of a singleton class or methods of a static class. I\'ve already seen this so I\'m no

Answer 1

In previous tests that I've done, I've found that calling static methods is faster than calling instance methods, and fractionally more memory efficient.... but the singleton shouldn't be dismissed purely for those reasons.
