Incidentally, this kind of passive-aggressive pressure is the kind of thing that might be considered a legitimate security threat, post xz. If you need to vent, vent in private. If “it works for you” but the maintainer is asking legitimate questions about the implementation, consider engaging with that in good faith and evaluating their questions with an open mind.

Which mantra is that? The ellipsis doesn’t offer a clue.

Casey’s video is interesting, but his example is framed as moving from 35 cycles/object to 24 cycles/object being a 1.5x speedup.

Another way to look at this is, it’s a 12-cycle speedup per object.

If you’re writing a shader or a physics sim this is a massive difference.

If you’re building typical business software, it isn’t; that 10,000-line monster method does crop up, and it’s a maintenance disaster.

I think extracting “clean code principles lead to a 50% cost increase” is a message that needs taking with a degree of context.
