FreeBSD Quarterly Status Report, January-March 2014

FreeBSD is a fantastic operating system and this report highlights why. Documentation is something the team takes very seriously; as important as the code itself, so if you're impressed by this high-quality report you'll be even more impressed by how easy it is to find your way around FreeBSD because of the documentation.

I too noticed the quality of the report. I know what it is and what it is for as soon as I start reading. Well laid out, succinct, contact details and further links for each item.

It's all very encouraging.

Enticing; depth and vision. Coherence is always tricky, but, to my mind, they pull it off.

To be quite honest: Debian/kFreeBSD is still my version of FreeBSD, but that's just laziness.

This report has only made me want to try FreeBSD even more at some point.

Some highlights for me were:

- FreeBSD on Chromebook - Chromium port - Improved Wine port

Ha, you beat me to it! https://wiki.freebsd.org/FreeBSD/arm/Chromebook

I bought a refurb Acer C720 4gb and have found it perfect for everyday tasks / general use with Ubuntu installed.

I haven't been able to find the 4gb model, where did you get it?

Not the GP, but I was able to pick up a new 4gb model from the Acer online store a few weeks ago (the Canadian store - I don't think Acer is selling it new in the US anymore).

If you're unable to find one I believe the new Dell Chromebook 11 is fairly similar.

Marginally relevant - are ARM Chromebooks any good for development? I've been considering getting a Samsung Chromebook 2 when it comes out, but I'm concerned that important software won't be available for ARM.

Anyone running crouton on an ARM Chromebook care to comment?

I've similar feelings about ZFSGuru. Never heard of it before; might download it and give it a whirl.

I love FreeBSD and was planning on switching some servers from Linux but found that it consumed about 25% more power than my Linux boxes (even after extensive power management tweaks) and in the end didn't have much advantage.

It's not hard to install freeBSD in a VM, set up ssh, run it headless, and ssh in. I suggest you give it a go. It's a great learning experience.

Wow, I wouldn't have thought there would be such a dramatic difference in power consumption on anything but portable hardware. Did you try to measure the CPU and I/O usage on your servers and compare them between Linux and FreeBSD? I wonder if FreeBSD's greater power draw was due to its ACPI implementation or if the average system load was also higher (ZFS?).

I wasn't using zfs at the time and I didn't do much comparison with CPU and IO, I used a wattage meter. I followed the FreeBSD guide (http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/ac...) and tried just about everything. My Linux box was running at about 9watts (idle) and freeBSD started out at around 18, but I got it down to about 12watts after making a lot of optimizations.

I think most of the difference is because FreeBSD is using older more stable software, and the Ubuntu server was running some of the latest software.

Do you remember which FreeBSD version and which Linux kernel version was it?

Linux had tickless kernel + CPU scaling for a while. FreeBSD is lagging in this aspect.

The FreeBSD kernel is tickless as of FreeBSD 10:

Yes, exactly, it only has it for couple of months, that's why I asked about version.

I'd be interested to see some benchmarks comparing Linux and FreeBSD power usage. Personally I've been impressed w/ power management on FreeBSD 10 using recent hardware - once I enabled powerd and set the powerd_flags - but I haven't installed Linux on the same hardware.
