While for Intel x86_64 with the latest compilers it's a very competitive race between LLVM Clang and GCC, how is that battle playing out on the IBM POWER9 front? Using the interesting Raptor Blackbird with IBM POWER9 4-core / 16-thread CPU, here are some recent benchmarks I did between GCC 9, GCC 10, and LLVM Clang 8.

While debating new CPU requirements for Fedora 32 potentially taking it all the way to AVX2 CPUs as a new base requirement, before that Fedora 31 still needs to get finished up and there is some late feature work happening for this current cycle...

While AMD developers published their "Znver2" compiler patches for Zen 2 originally back in November, months ahead of the recent Ryzen 3000 series launch, this compiler support was incomplete as it re-used the existing scheduler model and costs table of Znver1. Now though one of SUSE's compiler experts who often works in cooperation with AMD has published the new Znver2 scheduler model and costs table for Zen 2...

Looking ahead to Ubuntu 19.10 as the cycle before Ubuntu 20.04 LTS, one of the areas exciting us with the work being done by Canonical is (besides the great upstream GNOME performance work) easily comes down to the work they are pursuing on better ZFS On Linux integration with even aiming to offer ZFS as a file-system option from their desktop installer. A big role in their ZoL play is also the new "Zsys" component they have been developing...
