Even more PostgreSQL benchmarking

Jan Lentfer’s done some new benchmarking of PostgreSQL on Hammer.  There’s further suggestions and a more complete benchmark is planned, taking advantage of the Hammer improvements in 2.6.  In the meantime, you can look at previous benchmarks.

DragonFly 2.6 released!

DragonFly 2.6 is out!  Download from a mirror, check the release page, and enjoy the large number of new features.  There’s a full set of binary packages built, too.

Technically, this is 2.6.1, since 2.6.0 was tagged a week ago and 2.6.1 has all the last minute fixes since then.

Someone please make this video

Gource is a tool for visualizations from version control history; the video page has some examples.  (via)  I’d love to see this run on DragonFly.  I’m curious to see what would happen on a huge, old repo, like NetBSD.  Please hlep me, intarwebs!

2.6 release imminent

2.6 will probably be out within the next 24 hours. We’re just waiting on the packages, though we’re probably in the clear already.

Be ready for mild confusion with this and the current Linux kernel.  I know it’ll happen.

Hammer and OS X

Daniel Lorch has ported Hammer to Mac OS X, of all things.  It’s not complete, but he’s moving right along.

dsched details

Alex Hornung has posted an elaborate summary of his I/O scheduler work, with details on usage.  He reports speed improvements under heavy load.  If this sounds interesting to you (and it should), it’s possible to test his changes right now.

OpenSSL bug fixed, BIND updated too

OpenSSL (which recently hit 1.0, though that’s not in DragonFly yet) has been patched to cover a recent security issue, thanks to Peter Avalos.

Jan Lentfer’s updated BIND to 9.5.2-P3, too.

Panic, and fast

Venkatesh Srinivas’s new sysctl, “debug.panic” is available for those who want to panic their machine on purpose, but don’t have direct access to the keyboard.

Recent performance improvements

A problem found by Jan Lentfer and fixed by Matthew Dillon means that you can get a good performance boost if you’re running bleeding-edge DragonFly from the last month or so.  Or, you can just wait a week for the 2.6 release.

I/O scheduler preview

Alex Hornung has been working on an I/O scheduler; he’s made some graphs to show results so far.   They’re plain, but pictures are always fun.

Flash works too!

Thanks to work from Samuel J. Greear and Alex Hornung:

  1. Install Firefox (natively)
  2. libflashsupport and adobe-flash-plugin
  3. mount linprocfs
  4. null mount devfs within the linux system

There’s occasional video and audio sync problems, but Johannes Hofmann has already found a fix.

Pretty, big graphs

This set of graphs that shows relationships within given languages on github shows some interesting relationships, and also happens to be very pretty.

Would it be worth moving DragonFly to github for the additional services?  I’m not qualified to answer.

New bugtracker possibilities

Alex Hornung has suggested replacing the existing bugtracker (Roundup) with a new one (Redmine).  His post about the changes is lengthy and links to a demo, so read on for details; I haven’t had a chance to look at it in full, yet.

cvsup gone, finally

YONETANI Tomokazu has eliminated cvsup, replacing it with net/csup from pkgsrc. The README notes that the pkgsrc package devel/cvsync is another alternative if you need to retrieve the repository and not just the checked out files..

REDOs done, and 64-bit vkernels too

Matthew Dillon has implemented what he calls “REDO” records in Hammer, which reduce the amount of time taken flushing data to disk.  It’ll be in the 2.6 release, but it isn’t on by default.

Jordan Gordeev’s work on 64-bit vkernels has also been brought in, so virtual systems are now available for x86_64 users.

Matthew Dillon’s added some tools for building system snapshots, a previously custom process.  Look at the README for details.
