Indeed, a very interesting article! Thanks for posting that link.
I notice that the tests didn't include numbers for -Os. I suspect, however, that -Os might not fare as well as other optimizations in relatively pure CPU benchmarking (i.e., my hunch is -Os would be more competitive in situations where disk and RAM speed come into play more than in benchmarks intented to stress the CPU in relative isolation). Does that seem reasonable? |

Yes. I thought the same. O3 might be blazing fast on your CPU, but the disk access times (and whatnot) have been excluded in this test. And they do make a difference.
It's not just the CPU you're optimizing for, its the rest of the system too.... If you build a 2500+ Athlon with an old and slow 1.6 GB Seagate disk and use O3, you're basically saying that you like to flog old drives to their deaths.... |
