Phoronix posted an article comparing performance for newest release of Dragonfly BSD. The comparison made is between the old release (5.2) and the new release under development (5.3).
Overall, performance looks improved from new to older release. Unclear how this compares against other operating systems.
Below is a table of overall observations as well as my comments on the benchmarks.
|Benchmark||Phoronix observations||My observations||Analysis|
|sqlite||New release is 1.3x faster||Single-threaded program. Database using a file with file locking.||Analysis|
|compilebench||New release is slightly faster||File system performance with only 1/7th of a core scheduled.||Analysis|
|rodinia||performance is the same||OpenMP, 100% CPU with varying amounts of backend stalls.||Analysis|
|polybench-c||performance is the same||Memory bound linear algebra operations.||Analysis|
|fftw||New release is faster||Single threaded, Short vectors are high IPC. Long vectors are limited by memory.||Analysis|
|go-benchmark||http workload is faster, others are the same||GO language; http is ~20% system time, others less.||Analysis|
|java-scimark||performance is the same||Java wrappers around backend bound compute. Single-threaded.||Analysis|
|java-gradle-perf||performance is slightly faster||Build system, many small processes. On_CPU of 31%||Analysis|
|build-php||performance is slightly faster||Build system, On_CPU of 82% with frontend stalls.||Analysis|
|pgbench||performance is slightly faster||Database with frontend stalls. On_CPU of 60%.||Analysis|
|pybench||performance is slightly better||Single-threaded python. High IPC||Analysis|
|phpbench||performance is slightly faster||Single-threaded php with high IPC||Analysis|
|osbench||individual components are mixed||Unit tests for OS operations, e.g. threads, processes, files.||Analysis|
