A Look At The HAMMER2 File-System Performance With DragonFlyBSD 5.2

Filed under
Graphics/Benchmarks
BSD

With this week's release of DragonFlyBSD 5.2 this popular BSD operating system is promoting its own HAMMER2 file-system as stable. As a result, here are a few fresh benchmarks of HAMMER vs. HAMMER2 on DragonFlyBSD 5.2 while more tests are forthcoming.

HAMMER2 received many improvements during the DragonFlyBSD 5.2 development cycle to the point where they now recommend HAMMER2 as the default root file-system for non-clustered systems; the clustered mode for HAMMER2 is yet to be implemented.

On Phoronix we have been covering the HAMMER2 file-system since its inception back in 2012 and have been benchmarking it more recently since it became a fairly viable choice in DragonFlyBSD 5.0. HAMMER2 is a clean sheet design and supports online deduplication, snapshots, LZ4/Zlib compression, encryption, and other features. Our tests have been positive and in the testing of DragonFlyBSD 5.0 and 5.2 we have yet to lose any data to this file-system led by DragonFly lead developer Matthew Dillon.

Some FreeBSD 11.1, 12.0-CURRENT & TrueOS 18.03 Benchmarks

Filed under
BSD

In addition to the overhauled/rewritten Windows support, the upcoming Phoronix Test Suite 8.0-Aremark is also featuring much better support for the BSDs. As part of that testing, here are some fresh benchmarks of FreeBSD and TrueOS.

While running some fresh benchmarks this week, here are some test results using FreeBSD 11.1-RELEASE as it debuted last year, FreeBSD 11.1-STABLE with all current updates including for Spectre/Meltdown mitigation, FreeBSD 12.0-CURRENT as its current form of development and with Spectre/Meltdown mitigation and note that FreeBSD CURRENT ships with some debug bits enabled, and then the recently released TrueOS 18.03 that is derived from FreeBSD 12.0-CURRENT and also mitigated against Spectre/Meltdown.

BSD: More on OpenBSD 6.3 Release and KDE in FreeBSD

  • OpenBSD 6.3 released ( Download of the day )
  • OpenBSD 6.3 released
  • The Shoving Continues

    More KDE4 parts have been moved around on FreeBSD. Basically what we’re seeing is that all the existing KDE4 ports — that is, pretty much all KDE software except the KDE Frameworks 5, which are the kf5-* ports already available — are getting a -kde4 suffix. I resurrected the old filelight from KDE4 times, which we had updated to the modern KDE Applications version some time ago. That is so that KDE4 users can get the authentic (in the case of filelight-kde4, I think that also means “buggy”) experience. Users of x11/kde4 are encouraged to update and upgrade regularly these days, to catch all of the moves of packages. There are no actual updates in here, no new packages, since there aren’t any more upstream releases.

TrueOS STABLE 18.03 Release

Filed under
BSD

The TrueOS team is pleased to announce the availability of a new STABLE release of the TrueOS project (version 18.03). This is a special release due to the security issues impacting the computing world since the beginning of 2018. In particular, mitigating the “Meltdown” and “Spectre” system exploits make it necessary to update the entire package ecosystem for TrueOS. This release does not replace the scheduled June STABLE update, but provides the necessary and expected security updates for the STABLE release branch of TrueOS, even though this is part-way through our normal release cycle.

Elementary OS Juno Beta 2 Released

Elementary OS June beta 2 is now available to download. This second beta build of the Ubuntu-based Linux distribution touts a number of changes over the elementary OS june beta released back in July. Due to the shifting sands on which Juno is built the elementary team advise those planning on testing the release to do so by making a fresh install rather than doing an upgrade from beta 1 or (worse) an older version of elementary OS.

Linux - The beginning of the end

You should never swear at people under you - I use the word under in the hierarchical sense. Colleagues? Well, probably not, although you should never hold back on your opinion. Those above you in the food chain? It's fair game. You risk it to biscuit it. I say, Linus shouldn't have used the language he did in about 55-65% of the cases. In those 55-65% of the cases, he swore at people when he should have focused on swearing at the technical solution. The thing is, people can make bad products but that does not make them bad people. It is important to distinguish this. People often forget this. And yes, sometimes, there is genuine malice. My experience shows that malice usually comes with a smile and lots of sloganeering. The typical corporate setup is an excellent breeding ground for the aspiring ladder climber. Speaking of Linus, it is also vital to remember that the choice of language does not always define people, especially when there are cultural differences - it's their actions. In the remainder of the cases where "bad" language was used (if we judge it based on the approved corporate lingo vocab), the exchange was completely impersonal - or personal from the start on all sides - in which case, it's a different game. The problem is, it's the whole package. You don't selective get to pick a person's attributes. Genius comes with its flaws. If Linus was an extroverted stage speaker who liked to gushy-mushy chitchat and phrase work problems in empty statements full of "inspiring" and "quotable" one-liners, he probably wouldn't be the developer that he is, and we wouldn't have Linux. So was he wrong in some of those cases? Yes. Should he have apologized? Yes, privately, because it's a private matter. Definitely not the way it was done. Not a corporate-approved kangaroo court. The outcome of this story is disturbing. A public, humiliating apology is just as bad. It's part of the wider corporate show, where you say how sorry you are on screen (the actual remorse is irrelevant). Linus might actually be sorry, and he might actually be seeking to improve his communication style - empathy won't be part of that equation, I guarantee that. But this case - and a few similar ones - set a precedence. People will realize, if someone like Linus gets snubbed for voicing his opinion - and that's what it is after all, an opinion, regardless of the choice of words and expletives - how will they be judged if they do something similar. But not just judged. Placed in the (social) media spotlight and asked to dance to a tune of fake humility in order to satisfy the public thirst for theatrics. You are not expected to just feel remorse. You need to do a whole stage grovel. And once the seed of doubt creeps in, people start normalizing. It's a paradox that it's the liberal, democratic societies that are putting so much strain on the freedom of communication and speech. People forget the harsh lessons of the past and the bloody struggles their nations went through to ensure people could freely express themselves. Now, we're seeing a partial reversal. But it's happening. The basket of "not allowed" words is getting bigger by the day. This affects how people talk, how they frame their issues, how they express themselves. This directly affects their work. There is less and less distinction between professional disagreement and personal slight. In fact, people deliberately blur the lines so they can present their business ineptitude as some sort of Dreyfuss witchhunt against their glorious selves. As an ordinary person slaving in an office so you can pay your bills and raise your mediocre children, you may actually not want to say something that may be construed as "offensive" even though it could be a legitimate complaint, related to your actual work. This leads to self-censored, mind-numbing normalization. People just swallow their pride, suppress their problems, focus on the paycheck, and just play the life-draining corporate game. Or they have an early stroke. Read more Also: Google Keeps Pushing ChromeOS and Android Closer Together
