    It's consistent with the benchmarks that ran the last few years. Clear linux was always 3.5-4x faster at LAME wav to mp3 than other distros.

    It's hard to see the compiler settings, but they are in the image:
    Code:
    -O3 -pipe -fexceptions -fstack-protector -m64 -ffat-lto-objects -fno-signed-zeros -fno-trapping-math -fassociative-math -mtune=skylake -lncurses
    Now why this is so, I don't know.

    Phoronix: Clear Linux Offering Performance Advantages Even With Low-Power IoT/Edge Hardware

    While we are often testing Intel's Clear Linux on high-end desktop and server hardware, it turns out even on the opposite end of the spectrum that their performance-optimized distribution can offer meaningful performance advantages on low-end SoCs for IoT-type devices. When testing Clear Linux with an Apollolake platform, it came out to being about 20% faster than the likes of Fedora and Ubuntu Linux.
