During my searches I stumbled upon PHP PGO
PGO refers to Profile-guided Optimization. It is a self-adaptive optimization which means it doesn’t make improvements on the software code itself to achieve performance enhancements.
So I thought I’d dig a bit deeper, but not now. I will come back to this later. Here are some helpful links though.
