With the OSBench "create files" benchmark there was slightly less latency on FreeBSD 15.0 than FreeBSD 14.3.
Benchmarking other operating system primitive operations with OSBench showed little difference on FreeBSD 15.0.
With LLVM Clang 19 on both FreeBSD 14.3 and 15.0 via the pkg archive, for many user-space applications there was no real performance difference observed with the new FreeBSD 15.0 installation.
In some of the OpenJDK Java benchmarks there were some slight improvements to be found with FreeBSD 15.0 but overall the performance was largely flat compared to FreeBSD 14.3 with using OpenJDK 23 on both.
