Re: Speed of interfaces vs inheritance

In a particularly time-critical part of my app I need to call a method on
an external class in a tight loop. The class can be different in different
contexts. I've got two choices: create an interface and have the various
different classes implement it, or create an abstract class and have the
various different classes extend it.

I seem to recall, in years past, that the interface approach was slower.
Is this still the case?

(In this particular situation, either approach works fine, though I
personally like the interface approach better).

The only way to answer this question is to write a test.
