The article mentioned shows the worst case being closer yo 10%
> Compiling the kernel turned out to be 2.4% slower, and a Blender test case regressed by 2%. The worst case appears to be Python programs, which can see as much as a 10% performance hit. To many, these costs were seen as unacceptable.
Sacrificing that much for the absolute minority of people that need to dig that much into performance doesn't seem to be worth it for distro. Would be interesting to see why some cases still get that much regression tho.
- rwmj 4y agoThat's a very specific case (the Python interpreter main loop), and for that reason the Python interpreter is still using -fomit-frame-pointer. It is specifically called out in the Fedora Change: https://fedoraproject.org/wiki/Changes/fno-omit-frame-pointer#Benchmarking_of_the_performance_impact https://fedoraproject.org/wiki/Changes/fno-omit-frame-pointe...
- mouse_ 4y agoWhile it may be true that only the absolute minority actually push computing forward and optimize things, sidelining that minority will have disastrous consequences for everyone.
- saagarjha 4y agoWhen performance people are telling you to leave some on the table, there's generally a very good reason for it.
