This week brought the official release of FreeBSD 15.0 as the latest major update to this BSD operating system. In being eager to test out this new FreeBSD release, for this first round of FreeBSD 15.0 benchmarking is seeing how it compares to the former FreeBSD 14.3 release on a Supermicro + AMD EPYC Turin server.
For this first round of FreeBSD 15.0 benchmarking is seeing how the performance compares to the prior FreeBSD 14.3 release. Both FreeBSD releases were installed from scratch on the same exact server: a DIY build using the Supermicro H13SSL-N 1P board for AMD EPYC 9004/9005 CPUs, AMD EPYC 9655, Micron 7450 Max NVMe SSD, and 12 x 64GB DDR5-6400 memory.
Via pkg both FreeBSD 14.3 and FreeBSD 15.0 provided the LLVM Clang 19.1.7 compiler, Python 3.11.13, OpenJDK 23, and many other common user-space packages so it largely the benchmarking comes down to the kernel impact of FreeBSD 15.0 on this 5th Gen AMD EPYC server with 192 threads.
Both FreeBSD releases had installed without issue on this Supermicro AMD server with all typical functionality working.
