FreeBSD 12.0 vs. DragonFlyBSD 5.4 vs. TrueOS 18.12 vs. Linux On A Tyan EPYC Server

Under the CompileBench program with its I/O heavy initial create process, DragonFlyBSD 5.4.1 was the slowest by far on HAMMER2 with this EPYC server. CentOS 7 to little surprise was the slowest Linux distribution but still three times faster than DragonFlyBSD. Coming just ahead of CentOS 7 were TrueOS and the FreeBSDs. In this particular case, FreeBSD 11.2 had a slight performance advantage over the latest 12.0 release. Clear Linux and Ubuntu meanwhile were much faster.

During the compile process, FreeBSD had a narrow advantage over Ubuntu and Clear Linux followed by TrueOS, CentOS, and then DragonFlyBSD in a distant last.

For the HTTP performance with Golang, Clear Linux was the fastest followed by DragonFlyBSD 5.4.1 and then Ubuntu 18.04.1 LTS. (Golang wasn't tested on CentOS 7 due to not having Go in its default repository). The FreeBSD-based operating systems were quite slow in this test.

DragonFlyBSD pulled back in the other Golang benchmarks while FreeBSD 11.2 was the fastest BSD configuration for Go in these other micro-benchmarks.

In the basic Java benchmark of SciMark2, Clear Linux and FreeBSD 11.2 were competing for a narrow first-place competition.

In the other Java-based DaCapo tests, Clear Linux came out in front to varying lengths ahead of FreeBSD. DragonFlyBSD 5.4.1 was coming in surprisingly slower than the FreeBSDs.
