Published to a DragonflyBSD mailing list this week were some benchmarks that show the performance of the DragonFlyBSD 3.2 operating system as of 10 October and then compared to DragonFlyBSD 3.0, FreeBSD 9.1 RC1, NetBSD 6.0 RC2, and Scientific Linux 6.2.
While the information is limited, for a dual-socket Intel Xeon 5650 system with 24GB of RAM, there's dramatic performance improvements in DragonFlyBSD 3.2 over the current DragonFlyBSD 3.0 stable release.
Not only are the DragonFly BSD 3.2 improvements over 3.0 alone impressive, especially as the number of PostgreSQL clients increase, but the performance against Scientific Linux 6.2 is particularly interesting. When running just a few database clients, DragonFlyBSD 3.2 appears faster than this community rebuild of Red Hat Enterprise Linux 6.2. When the number of clients go past 24, Scientific Linux takes over but DragonFlyBSD 3.2 remains competitive. DragonFlyBSD 3.2 also wipes the floor against FreeBSD 9.1 RC1 and NetBSD 6.0 RC2.
New Phoronix benchmarks of the popular BSDs against Linux will be on call as soon as DragonFlyBSD 3.2 is released later this month along with the release of FreeBSD 9.1. For now you can find some current BSD benchmark results by searching BSD on OpenBenchmarking.org and DragonFly performance benchmarks.
