openSUSE Tumbleweed vs. Leap 15.2 vs. Jump Alpha Benchmarks
Where having the older compiler tends to pay off is in compilation speed with producing binaries faster due to less optimization passes, etc, employed by newer compiler releases.
Not only was Jump performing noticeably slower than Leap for the compilation speed, but in the DeepSpeech speech-to-text engine benchmark Jump wounded up being much slower than Leap and Tumbleweed -- but it's alpha at this point anyhow.
The newer build of Hugin really paid off with Tumbleweed if you are frequently using this photo panorama stitcher.
RawTherapee similarly enjoyed a nice boost out of Tumbleweed.
