NetBSD 5.0 vs OpenBSD 4.5 vs FreeBSD 8beta2 vs Linux Ubuntu 9 vs OpenSolaris 2009/06 vs DragonFlyBSD 2.2.1

Ruby Benchmark Suite

All default installs plus the following changes. 

FreeBSD: rebuilt GENERIC without WITNESS/INVARIANTS

OpenBSD: had softdeps enabled, and booted bsd.mp

NetBSD: had wapbl enabled

Dragonfly: Does not ship with MP capable kernel. Created one, but hangs during boot on this system.

DragonflyBSD should be included in UP run, but it's here for completeness. Since 1.8.7 is not using native threads this should not be a problem.

Test System: Dell PowerEdge 1750 Dual Core Xeon 2.8 Ghz 2 GB (DDR2 SDRAM) with HT disabled

Each run was done after a cold boot

A fresh install was done for each OS

All tests were run on Ruby 1.8.7-p174 MRI compiled by hand

with configure --prefix /tmp

The mean value was plotted for each test. (five iterations each)

Raw data from the benchmarks can be taken from here

Charts are not shown for any of the tests where one or more OSs failed to complete them.
