Benchmarks: FreeBSD 13 vs. NetBSD 9.2 vs. OpenBSD 7 vs. DragonFlyBSD 6 vs. Linux
For the LibRAW image decoder library, Clear Linux with its default aggressive compiler flags led to the best performance by far over any other operating system tested. The BSDs were in last aside from DragonFlyBSD 6.0.1 that was on par with Ubuntu 20.04.3 LTS.
Clear Linux also led over the rest with the Kvazaar H.265 video encoder while FreeBSD 13.0 was competing with the Linux distributions for this video encode benchmark. NetBSD and OpenBSD had issues building Kvazaar.
Only the security-minded OpenBSD's performance for the x265 H.265 video encoder was well off compared to the other Linux distributions due to it avoiding Hyper Threading by default.
OpenBSD 7.0 also took much longer as a result when it came to code compilation workloads.
