The Fastest AArch64 Linux Distribution On The 192-Core AmpereOne
With AmpereOne enjoying upstream Linux support for a while, in some workloads there was very little change between operating systems.
Ampere Computing tends to do most of their public Linux testing on Fedora and Ubuntu Linux. In some of the benchmarks Ubuntu 24.04 LTS was indeed running the fastest while in some scenarios AlmaLinux 9.4 was the slowest. AlmaLinux 9 / RHEL9 being the slowest is hardly a surprise compared to the other Linux distributions on newer compilers, newer kernels, etc. The good news though is RHEL 10 is coming and the early CentOS Stream 10 performance is looking nice.
Ubuntu and Fedora both experienced surprisingly low performance with the LULESH hydrodynamics software compared to the rest.
