Intel's Linux Software Optimizations Still Pay Off For Xeon 6700E "Sierra Forest" E-Core CPUs

When testing Intel's aggressive software Linux optimizations shipped by way of their in-house Clear Linux distribution, I am most often testing it on their high core count Xeon processors with AVX-512... Over the years in dozens of Phoronix articles there have been countless metrics showing off the out-of-the-box performance benefits from leveraging software built for higher x86_64 micro-architecture feature levels, employing compiler-based function multi-versioning, and the other extensive performance tuning carried out by Intel software engineers. But now with the Intel Xeon 6700E "Sierra Forest" series now being available for these all-E-core server processors, I was curious about quantifying the Clear Linux benefits over the likes of Ubuntu Linux. Here are those benchmarks for those curious about the difference.
