Intel Xeon Cascade Lake Running Even Faster With Clear Linux - Six Linux Operating Systems Benchmarked

Clear's tuning also paid off when it came to running the Apache HTTPD web server benchmark with Siege.

Lastly was the BRL-CAD solid modeling benchmark where Clear Linux ended these Linux OS benchmarks with another measurable win.

Of 42 benchmarks carried out on the six Linux distributions, Clear Linux had the most wins with 22 (52% of the time) while coming in second place for the most wins was Ubuntu 18.04.2 LTS at 10 (24%) followed by Debian 9.8 with five wins (12%). CentOS 7 was in last place most often at 52% of the time, which isn't too surprising due to the much older kernel and GCC compiler showing its age on newer hardware platforms, but at least RHEL 8 / CentOS 8 will finally be out later this year.

Here is a look at the geometric mean of the tested Linux distributions for all of the workloads that successfully ran on all six operating systems. Clear Linux was in first with an 8% lead over the next fastest distribution, Ubuntu 19.04 beta, which was then followed shortly thereafter by Ubuntu 18.04 LTS and Debian 9. In going from CentOS 7 (EL 7) to Clear Linux was a 60% improvement in the out-of-the-box performance based on the current geometric mean.

That's the performance data for those wondering about the out-of-the-box Linux performance on Xeon Cascade Lake... Stay tuned for our BSD compatibility and performance benchmarks next week from this latest Intel hardware and Gigabyte Storage Server.
