And the graphs as promised, in the attached PDF files.
This is a bit later than originally announced; some kernel parameters kept
being tweaked for a long time, preventing me to post soon-to-be-obsolete
numbers.
Pg-benchmarks.2012-10.pdf shows a comparison between DragonFly-3.0 and the
soon to be released 3.2 version.
For kicks there are also a few graphs of Linux, FreeBSD and NetBSD on the
second page, showing where we stand.
Pg-benchmarks.2012-10.improvements.pdf can be thought of as an historical
record showing the results of some of the many performance tweaks and new
features recently added to DragonFly, with commit numbers.
Enjoy!
