What is "specific" supposed to mean? It doesn't seem to be very
"specific". This benchmark reflects a general tendency which can also be
observed by the vast of benchmarks "Phoronix" performed.
I guess FreeBSD has been benchmarked with ULE. ULE does have issues and
it's obvious, that ULE performs in specific situations better than the
legacy and old (but after so many years still competetive) BSD scheduler.
