Page 3 says FreeBSD is 2X faster (200% bogo ops) than Linux on the semaphore benchmark, 3X on function calls, 7X on poll, and 15X (!) on context switching. Of course it shines with lots of cores. It's strange that Linux comes up 3-5X faster on socket activity, given that networking is supposed to be BSD's strength. Maybe FreeBSD just does things a different way that sidesteps the benchmark tests for those OS-related ops, so those results aren't really valid? Or does anyone see these differences in the real world, and if so why is BSD faster?

1st, I appreciate Phoronix for continuing to do these benchmark. Yes, all benchmarks are flawed - but at least he still does them since few if any do anymore. 2nd, even though the article concludes that FreeBSD is the fastest, it’s skewed. Because in the test that most would encounter (eg PHP or SQLite) it’s the slowest. Even slower than DragonflyBSD. https://www.phoronix.com/review/bsd-linux-threadripper-7980x/4 https://www.phoronix.com/review/bsd-linux-threadripper-7980x...

  Why do you say most? Where’s the data on that? And it’s not like the performance is 2x worse like dragonfly bsd or netbsd is for many benchmarks…

Ah it would’ve been great to see Openbsd in those benchmarks as well.

  fta: "Originally the plan was to also have OpenBSD 7.5 in the mix but that BSD operating system was having issues on the system under test. OpenBSD 7.5 booted fine from USB for installation but when it came to post-installation use when booting the installed system the display wouldn't work nor was there any network connectivity and thus no ability to SSH into the system. So something was going awry with the current OpenBSD release on this high-end workstation system while at least FreeBSD, DragonFlyBSD, and NetBSD all worked fine with their latest releases."

I don't know about the actual truth, but my feeling is that FreeBSD has gotten a lot faster in recent years. Some of the netflix patches literally made some of my workloads 20% faster over night.

  AFAIK NetFLix is a rare company that actively makes substantial contributions to open software, i.e. FreeBSD in their case. There are lots of Linux distros and thus you will never get the cohesion that you get with any of the BSDs.
