The Ubuntu Linux Performance Over The Past Six Years On An Intel Xeon Server

The EXT4 read performance on the Hitachi SAS drive didn't change all that much in the past six years, the sequential read performance was in fact a few MB/s slower.

The sequential write performance was also slightly lower with Ubuntu 18.10 over 12.10, granted in the past six years EXT4 has picked up new features including reliability improvements.

In the synthetic CompileBench test that simulates code compilation performance, this is one of the tests impaired a great deal by the Spectre/Meltdown performance leading to much lower performance now than back when this SunFire server was new.
