Matthew Dillon has been testing on more NVMe hardware, or at least what is supposed to be NVMe hardware, and he has a writeup of the results that may be useful for anyone planning a shopping trip soon.
Remember Sepherosa Ziehau’s nginx tests on DragonFly? He’s using the same configuration to test performance of the accept(2) and close(2) calls. The result? Over 8000 concurrent connections, for 580,000 connections per second. That’s on one DragonFly machine.
Matthew Dillon has written a new, from scratch, driver for NMVe in DragonFly. If you haven’t encountered it yet, that’s SSD access over PCIe, which gives better throughput than ATA. He’s posted a summary of his work, and it’s possible to load it now as a module. It supports MSI-X, and there’s test results from using dd on supported NVMe hardware.
I managed to not post about BSDNow (144: The PF Life) or garbage[28] (running with scissors for a while) last week, so I’m posting them now. That’s about 2 hours of BSD-ish conversation for you to listen to before this week’s episodes roll out.
This week is Esoterica week, for Lazy Reading.

Tomohiro Kusumi has finished his port of autofs to DragonFly; you can now have a filesystem automatically mount when accessed, rather than requiring it at boot.
If you are running DragonFly in a virtual environment, there’s been some improvements to virtio(4). Update and try if you’ve had problems in the past.
It’s a Solaris episode – or to be exact, SunOS, on BSDTalk this week. Sun used to be BSD, up to version 4.1.4, and this is 17 minutes of talk about that version.
Sepherosa Ziehau has been working on network performance, including making more network calls asynchronous. His test case using nginx shows that a single DragonFly machine can now take enough traffic to max out 2 10Gb links. That’s with 16Kb requests, and 30,000 of them at the same time.
What are people using for a web framework these days? I was messing with Fat Free Framework, and there seems to be about a zillion options, for many languages, these days.

The garbage[27] podcast is out, and it’s covering OpenBSD, iOS, and Android topics, or at least that’s what I guess from the summary, cause I’m still at work.
If you have a ral(4) wireless card that didn’t function as expected, it may suddenly work for you now on DragonFly 4.5 due to the large wifi update. The ral(4) driver covers a lot of hardware, so check the man page for all the commercial names.
BSDNow 143 has the usual roundup of news, plus a conversation with Matthew Macy about graphics improvements in FreeBSD.
We need DragonFly people interviewed, since DragonFly graphics improvements have been leading the pack, so to speak. I’m linking to the Jupiter Broadcasting site again since I don’t see this episode up on the BSDNow site yet.
A reminder: Dru Lavigne is talking at KnoxBUG tomorrow (the 26th) at 6 PM. I’ve met Dru and she’s a good speaker with a wide range of experience – catch it if you are anywhere near.
Matthew Dillon and Adrian Chadd have updated the wifi setup in DragonFly, incorporating Adrian’s FreeBSD changes (and merging back some of Matt’s from DragonFly). This affects the ath, rum, iwm, iwn, run, bwn, urtwn, wi, ral, iwi, ndis, and wpi drivers. The ‘an’ driver has been removed, too. I’m not going to even try to link to all the commits.
If you’re on DragonFly master and are using one of these devices, now is the time to update and try. Note that this removes the separate network interface that’s specific to the device and creates only a wlanX device.
Update: Matt reminded me that at least half the work came from Imre Vadasz; I missed it because I was only looking at the commit email names – mea culpa.
A nice wide range of topics, again!
