Slightly OT: speed of operation on a PC

A fundamental difference is that PGO requires a training run, and after that the code is static. A more dynamic system, like Dynamo, will rebuild the code as usage changes. Somewhat similar to rebuilding with PGO with a new training dataset, but on the fly.

Why would it? Depending on the architecture, comparing with 0 is often more efficient than with other values. Also multiplication is a much simpler operation than addition for floating-point values.

They might be equivalent for the OP. The OP might have additional knowledge on the values of a and b.
