Also -O3: https://www.phoronix.com/news/Ubuntu-Evaluating-O3-Optimized https://www.phoronix.com/news/Ubuntu-Evaluating-O3-Optimized
I am not sure off hand how that CPU level compares to Intel Clear Linux's options. The phoronix comparison fo Ubuntu with and without v3 were mostly quite small single digit percent though, on an Intel CPU.
Notes: Canonical (Ubuntu) is my employer, I am not working on this project.
- justinclift 2y agoHmm, -O3 at least used to have a bad reputation for producing potentially buggy and/or slow code. That was years ago though, and I have no idea if that's changed for the better.
- lathiat 2y agoI do solidly remember this from the "earlier" (200x) Gentoo days.
