Agree, especially when developing, I'd assume speed of optimizer matters more than quality of optimization. I wonder though if LLVM spent less time on that "phase ordering" problem, what is the tradeoff between these two factors?

LLVM doesn’t spend really any runtime solving the phase ordering problem since the pass pipelines are static. There have been proposals to dynamically adjust the pipeline based on various factors, but those are a ways out from happening.
