Performance comparisons: FreeBSD 7.1-R vs. 8.x
The files here depict results of testing a software build workload
that is performed under FreeBSD, and is important to my employer.
When we migrated the build machines' environmewnt from 6.2-R to 7.1-R,
we saw about a 35% reduction in build time, attributable solely to that
I was, therefore, unpleasantly surprised to find about a 20%
increase in elapsed time when I was able to test
FreeBSD8.1-STABLE r214029. I posted a note about this to
email@example.com; ref. the
In this directory, we have:
- A copy of the raw data, showing the output from time(1), in a
tab-separated format, for several iterations of the build in question,
in each of several different environments.
- A simple text file that provides information as to the meanings
of the various "environment tags" and how I abbreviated the data from
- A directory containing both individual files extracted from data.txt, as well as ministat(1) plots; each of the
latter has a filename that ends in ".plt".
- A directory that contains "boxplots" generated with the R
language, one for each datum produced from time(1), comparing the
results for each of the different environments.
