2021.08.10 in #525 Privacy and speed with Perl's Object::Pad
I have to admit I've never encountered a project where the speed problems were caused by the selected OOP system or just by using OOP and not functions. In my experience the database, algorithmic complexity, or using the disk instead of the memory always have a lot bigger impact on speed. So I think we agree with Mark. Cleaner code is (usually) more important than faster code.
