  • Some package statistics

    The article I linked yesterday about Ravenports got me wondering about what package are most popular. is the default binary package archive for pkg, and it has httpd logs back to 2013, so I collated some information. I read out a list of packages, and weighed them according to how recently they were downloaded.  […]

  • kcollect description

    I should have linked this yesterday: a description of kcollect and its uses from Matthew Dillon, complete with example graph of a very busy machine.

  • New mechanism: kcollect

    There’s a new facility in DragonFly: kcollect(8).  It holds automatically-collected kernel data for about the last day, and can output to gnuplot.  Note the automatic collection part; your system will always be able to tell you about weirdness – assuming that weirdness extends to one of the features kcollect tracks.  Here’s some of the commits.

    In what can be described as perfect timing, Sepherosa Ziehau has produced a document comparing FreeBSD, several different Linux kernels, and DragonFly, for networking.  He’s presenting it in the afternoon track of Day 3 for AsiaBSDCon 2017, starting later this week. He’s published a snippet as a PDF (via), which includes some graphs.    The one place […]
