According to the benchmarks when using the same compiler (LLVM) and the same file system (OpenZFS) FreeBSD performance is 98% of Linux performance. 2% performance penalty is a bargain in exchange for Dtrace, kqueue, pf, jails, ports, outstanding documentation, simplicity and cohesiveness of a FreeBSD system.
- toast0 6y agoLooking through the benchmarks, there's a huge variation here. For some tests, FreeBSD was much faster, and for some it was much slower. So, it depends on what you're doing. A lot of the tests where FreeBSD was much slower were media related; it makes me wonder if some CPU acceleration didn't get enabled; which could be FreeBSD (or Clang) missing a feature, or a benchmark issue or something else.
- rwaksmunski 6y agoFor media encoding you are essentially benchmarking the compiler. Sometimes makefiles force -O2 on BSDs vs -O3 on Linux, which should explain performance differences when using the same compiler.
