Without changing any compiler flags or the like from my source-based benchmarks, in a few of the HPC workloads I tested using the Ubuntu x86-64-v3 base did yield some small performance benefits.
For most of the HPC workloads though that were source based and no changes to the application themselves, the Ubuntu x86-64-v3 operating system didn't significantly impact the performance.
In some other source-based benchmarks without making any changes to the software build themselves, the optimized base OS did appear to provide some minor benefits.
👁 DaCapo Benchmark benchmark with settings of Java Test: GraphChi. Ubuntu x86-64-v3 was the fastest.
For some of the Java benchmarks when using the OpenJDK packages from the respective Ubuntu archive, the x86-64-v3 OS did yield some performance benefits.
