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.= --------------enigE68A23734FBCB71319668ECA Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iQEcBAEBAgAGBQJQlThiAAoJEOgBcD7A/5N8DzAIANayn2y7dXayOg7JtpUDJteE c9QbsWlvJ5uDPYLDQX7CvkT/BTVK5/n0yGFNbG95Pk2qCbO+0WKaXq6xjg8RHPH3 WwzP2jzYrAQAf2zUEUDHivb2z8zcHj/PYNFlInM44QGg/xF+Pl41RaDROQBWnHlG TxLguUDIkY7SoO5BUtJBiZ3qNkKfg6CdsAiqhByUA5+iUsaGzO1nGxk4mY2tFEwc /3h0vBsB3dMSsZ+qf4+OLrBh4S9RmRkkpE+/Ik6VN9RzJlCpM+tkZ/spS4hv3aha I5wq8Mk0fhTjkxjuwSn+4HuaNfF3ZOjUfz7ZvGw1INs84qgG1hcajK5hRRcnHp0= =LGcC -----END PGP SIGNATURE----- --------------enigE68A23734FBCB71319668ECA--
