Matthew Dillon’s committed some performance work for HAMMER2, dealing with write-clustering. I don’t have statistics to note, so here’s the commit message.
This timer fix enables booting DragonFly on AWS. Well, that and the ena(4) driver. I haven’t tried it yet.
If, like me, you’ve been running DragonFly for a long time, and you haven’t switched away from tcsh for your account or for root, you may not have ‘set autorehash’ in your .cshrc. Newer installs have it.
Put that into .cshrc if you don’t have it, and it’ll save 15 seconds of the rest of your life not typing ‘rehash’… assuming you can overcome the muscle reflex.

Matthew Dillon has committed two changes, both to DragonFly 5.4 and to DragonFly-current. His note to users@ explains the details. I don’t have a date for 5.4.2 being rolled out, but I expect soon.
This is the commit I should have linked to yesterday, and was reminded by an anonymous commenter: git: sys/vfs/fuse: Add initial FUSE support. It’s not complete, and so isn’t built by default; check the commit for details.
Remember my Wyse terminal experiment with a DragonFly VM? I mentioned an odd output pause where the screen would stop updating until there was keyboard activity – or occasionally just die. That was an artifact of Virtualbox; running this now in Qemu has no such problem.
I now have a very overcomplicated clock! I’m running GRDC on this Wyse-185 connected as a vt100 to the virtual machine running DragonFly 5.4 in Qemu on my Windows 10 work laptop. It’s at 9600 baud so I can see the numbers morph. I find this aesthetically satisfying.
Tomohiro Kusumi has committed more work on FUSE support in DragonFly. I am not sure if this is more foundational work or if it makes a user-level difference. At least the commit notes are nice.
Sepherosa Ziehau has an update for em(4)/igb(4) network cards, for you to test if you have the matching hardware. It looks like this is an update from the vendor, Intel, going by the version numbers.
The May NYCBUG meeting is tomorrow night, at 6:30 PM at Suspenders. The presentation is “Lookup Data Structures in the FreeBSD Kernel“. Go, if you are near.
Tonight’s KnoxBUG meeting is canceled at the last minute due to a family emergency. Don’t go, if you are near.

I have cleared out my backlog of general BSD stuff but am still a month behind on DragonFly news, which is the opposite of usual.
- OpenBSD 6.5 released.
- Michael W. Lucas’s FreeBSD Mastery: Jails is out.
- FreeBSD Mastery: Jails – Bail Bond Denied Edition.
- Related: Lucas is presenting for something like 24 hours straight at Penguincon 2019, including BSD topics. The ice cream-related presentations sound the most fun.

Michael W. Lucas is meeting one of his book sponsors tonight at the New Parthenon in Greektown – that’s in Detroit – and issued a general call for a get-together. If you attend SEMIBUG meetings, you’re probably close enough, but you don’t have to be an attendee to show up and have a good time.
This week’s BSD Now has traditional conversations: OpenBSD as a network device, NetBSD on different hardware, and something about ZFS encryption coming to FreeBSD after Linux. The show notes have details.
DragonFly now has ministat(1), imported from FreeBSD thanks to Aaron LI. Use it on the output from your next run of benchmarking tools.
See the page for details, and go if you are near. I’m saying “coming up” because there’s a big time zone difference between here and there.
time_t in DragonFly is now 48-bit. This won’t affect anything you do day-to-day, probably, but it’s neat to see the 9 million year timeframe.
DragonFly 5.4.2 is out. My users@ post describes upgrading, as do the 5.4 release notes. This release has the HAMMER2 fix mentioned here recently. There’s a number of additional small changes listed in the tag commit.
Images are available for download at various mirrors, too. If you’ve recently upgraded to 5.4, it’s the normal build process.
