Benchmarks: FreeBSD 13 vs. NetBSD 9.2 vs. OpenBSD 7 vs. DragonFlyBSD 6 vs. Linux
The file creation performance for that primitive operation measured by OSBench still heavily favors Linux over the BSDs. OpenBSD and NetBSD in particular out-of-the-box are much slower than the others.
For thread creation performance, FreeBSD 13.0 and NetBSD 9.2 managed to come out the best and even ahead the Linux distributions tested while DragonFlyBSD 6.0.1 and OpenBSD 7.0 were the slowest.
DragonFlyBSD 6.0.1 did perform on-par with the Linux distributions around program launching and process creation performance.
The malloc performance on FreeBSD, DragonFlyBSD, and NetBSD managed to come out faster out-of-the-box than the four Linux distribution configurations benchmarked.
