Intel 3rd Gen Xeon Scalable Linux Performance Evolution Since Launch

Enjoying huge gains with the latest Linux software stack was the DaCCapo OpenJDK benchmarks. OpenJDK and kernel improvements over the past year and a half yielded very nice speed-ups here. There is a large difference though with Ubuntu being much slower and in this case is largely due to Ubuntu's silly decision of still sticking to the Intel P-State "powersave" governor by default compared to Intel P-State "performance" as the default on both CentOS and Clear Linux. Particularly when running on server hardware it's frustrating to see Linux distributions still defaulting to powersave or ondemand.

With DaCapo's Jyton benchmark the performance wasn't changed much but just another example of the difference between Ubuntu and Clear/CentOS at the defaults.

In largely user-space bound software there weren't too many shifts from last year to the end of this year.

The Kvazaar open-source H.265 encoder was showing off some nice incremental improvements on the latest Linux distributions. CentOS and Clear Linux perform much better here due to their P-State performance default compared to Ubuntu.
