Canonical builders on Friday introduced that they’re reviewing the “-O3” optimization package deal that makes Ubuntu Linux. As a part of this overview of the usage of the optimized model of GCC’s -O3 compiler as an alternative of -O2 when growing Ubuntu applications, Ubuntu desktop and server ISOs are to be had to check with this modification. Funnily sufficient I ran the primary indicators over the weekend having a look on the distinction in efficiency.
Canonical hasn’t made up our minds if they will transfer to the “-O3” default optimization stage going ahead however it is excellent that they are having a look at… extra efficiency and may have the benefit of a extra optimized compiler stage. Being eager about quite a lot of different duties, I ran Ubuntu 24.04 LTS symbols put in correctly out of the field and repeated the blank set up of Ubuntu 24.04 LTS however the usage of -O3 construct ISOs. The take a look at used to be carried out from a System76 Thelio workstation powered by way of an AMD Ryzen Threadripper 7980X.
Except for the applications within the ISO -O3 take a look at builds, the set up of the APT setting on those ISOs issues to their take a look at repository which incorporates -O3 optimized applications. So putting in new Debian applications and different content material at the software will even obtain applications from the -O3 archive as an alternative of the previous/usual Ubuntu archive. I ran quite a lot of benchmarks the usage of the Ubuntu package deal to peer the variation the -O3 package deal makes.
