Ubuntu 18.10 Performance Is Looking Up, But Clear Linux Still Leads In Many Tests

The x265 video encode test was one of the extremes where Clear Linux's tuning offers much greater performance.

A few of the Intel systems saw better Himeno pressure solver performance on Ubuntu 18.10 that made it more competitive with Clear Linux while the AMD systems performed about the same in this particularly AVX-heavy benchmark.

In the Stockfish chess benchmark, Clear Linux generally maintained a small lead except for the Threadripper 2990WX box where Ubuntu was measurably faster.

For the common timed Linux kernel benchmark, on a number of the systems Clear Linux was building out the default Linux x86_64 kernel slightly faster than Ubuntu 18.04. On many of the systems with the GCC8 compiler on Ubuntu 18.10, the compiler speed is a little bit slower than Ubuntu 18.04 with GCC7.
