Right, my humor there was that I'm assuming people specifically did non-debug flags for the build as an optimization. Only for them to still fall short.
And understood a little on -O3 possibly increasing code size. I had thought that was more of a concern for tight environments than for most systems? Of course, I'd have assumed that -march=native would be more impactful, but the post indicates otherwise.
I said in a top level, but it seems the allocator makes the biggest impact for this application? Would be interesting to see which applications should use different allocators. Would be amazing to see a system where the more likely optimal allocator was default for different applications, based on their typical allocation patterns.
