Is openbsd really not so good in performance ?
Quote:
Taken from here: http://www.undeadly.org/cgi?action=a...20111018061633 I always here that freebsd is about performance and openbsd is about security. - |

The myriad of decisions made in development constantly juggles a number of conflicting needs, goals, desires, wants, & reality. Of greater importance is stability, & the fact that the OpenBSD project is small -- meaning that there aren't enough resources to focus on every issue at all times.
Do other *BSD's perform better at specific tasks? Some do. Is this important? For most people & tasks, no. |

People have to choose between performance and security
It was maybe serious question 10-15 years ago, when we had pentium 166mmx, and small amount of memory.
But today, instead of paying 50-100 dollars to the vps/dedicated server, just pay 150 and get openbsd. I mean, I can compensate the performance with more dollars but can you do it with security? NO Get a group of experts to develop a secure operating system for you, because in 2012 the net is so much crowded with hackers. The security of openbsd is much more then just 100 dollars. Not even 10,000 dollars. In 2000 performance is expensive but security is cheap. In 2012 performance is cheap but security is expensive. What do you think?

I see it big issue for people to decide between openbsd and freebsd.
The big idea is that they don't know the real story behind the scenes. Only developers can decide which to choose from. |

Or you can go the other way and use really old non-x86/amd64 hardware. I suggest you pick up a VAX. Now your decision becomes very easy. |

Hi barti !
When I first came to learn about the BSDs , I learnt 3 'labels' : OpenBSD : Security NetBSD : Portability FreeBSD : Usability This was not adequate as far as I -a user- am concerned Portability : both OpenBSD and NetBSD are portable to powerpc hardware but for my case OpenBSD was more successfully so ( easy install , working rum0, working X, etc) (maybe I'm not mistaken to think of portability as lame when not combined with ease) Security : all of them are secure and security-focused .. with slight differences with OpenBSD as king. Usability : What is it really ? if it means desktop experience : OpenBSD+Gnome or Kde reaches the same usability summit of PcBSD .. why bother ? if it means speed/responsiveness : it's rocking fast if it means lots of software : it has enough for me and zen choice works (eg. graphics : gimp and inkscape are enough for me .. for html pages , august and bluefish , Libreoffice for ) I did't miss a particular matter-of-life-or-death software. barti , what do YOU want ? I used PcBSD last year .. it was an easy big N slow Kde4 , so bloated.that wasn't the usability I wanted.PBIs make it worse. All in all, It's only you who can know what suits your needs. As ocicat told you (concerning window managers) : why not try some yourself and discover most suitable? same applies to OS choice.If I were in your shoes, I'd keep my newly hacked OpenBSD desktop .. and install FreeBSD on another disk or use a FreeBSD-based livecd (PcBSD may be used as a live , freesbie .. although live cds partially fail to show real performance) .. yet the real challenge for us newbies is : How to install the new OS + how to get X (desktop) working + software management If we start before gathering enough information from official websites , we get lost halfway or after first reboot (lol) (it happened to me when trying NetBSD eventhough the official guides are so great :-) ) So take your time to try & decide :-) |

- Flash support? (on FreeBSD You can use COMPAT_LINUX for that) - VirtualBox or any valuable alternative? (QEMU is dead slow) - Boot Environments or anything comparable? (sysutils/beadm) - Opera? (does it work using Linux compatibility layer on OpenBSD?) - Nvidia drivers? (there are none for OpenBSD as I know, this is blob but still provides acceleration) - Graphical Sound Configurator (PCBSD ONLY) - Graphical Jail Management (PCBSD ONLY) - if I recall there are no such thins like Jails on OpenBSD - Graphical Network Manager (PCBSD ONLY) If we compare 'Your' desktop experience, then even MINIX3 with some DE is usable ... What OpenBSD can offer besides not having these? Quote:

Hi vermaden ! I avoid adobe flash because it's been a security risk .. I use gnash+firefox .. and youtube-dl to download flash .. months ago , I fell in love with minitube :-) As for emulation , I pragmatically believe that a better way is using live cds/usbs , or simply dual-booting. As for Opera , I always use it on OpenBSD (despite it's being a closed source) .. its compilation is quite easy and fast .. (fedora_base , groff etc ) .. Nvidia : I have GeForce on Acer Aspire but really never bothered its existence .. I never go gaming ..OpenBSD doesn't claim being a gaming platform eventhough it does provide emulators like stella/mednafen/dosbox/zsnes .... and pop games PcBSD can't be a Linux-Killer as far as gaming is concerned .. it is as a matter fact a beginner's gateway toward BSD World .. other challenging gateways are on the way. Graphical utilities : what's the use having them while CLI works ? don't they threaten a user to learning about his OS internals etc ? and the PBI-way as graphical bundling too , doesn't it contradict UNIX & BSD philosophy? ( I'm asking to show that PcBSD dosn't do something OpenBSD cannot but simply doesn't consider doing because philosophies and thus concerns differ ) you mentioned graphical network management : I've never found as easier as OpenBSD's method : ifconfig/hostname.infterface0/netstart .. PcBSD doesn't help the user as learner .. and when it seems to do so : then it would be autokilling : that is : dropping PBIs for ports and dropping Graphical utils for CLI tweaks .. a waste. we forget sometimes that some 'OpenBSD's missing features' are due to the small Project Team , so focus is on priorities .. whereas some are developpers security-decisions OpenBSD really "makes me feel good" as newbie and am sure it will make me feel better as I advance in learning :-) & Respect to all BSDs.

There are even decent alternatives for all of these three. Many videos can be downloaded with cclive and get_flash_videos. Firefox and Chrome are both available. Well, maybe there’s no performant alternative to Nvidia drivers… but I don’t buy hardware from them precisely because their specs, docs, and drivers are all wholly proprietary. AMD and Intel both have decent open‐source drivers, and as a result they get my money. Quote:
Yes, we do seem to have different definitions of a “desktop system.” Is this OpenBSD fanboyism on my part? Hopefully not—I mean, I like NetSurf for web browsing and mupdf for PDF viewing, neither of which are part of base OpenBSD. I just think that smaller is better (i.e., as an aspiration, it’s more sustainable, even if it doesn’t provide all features that bigger programs provide). Well, for one, its culture doesn’t include things like the above that I disagree with. Here are some of the things that OpenBSD provides me:
Just because I like OpenBSD doesn’t mean that I dislike other BSDs. I eagerly salivate over stuff like FreeBSD’s work on LLVM and jails, or Dragonfly’s HAMMER and multicore support. Likewise, OpenBSD provides OpenSSH and pf to others. I would rather we worked on what we have in common rather than sniping over desktop choices. People have this strange desire to use Unity or Gnome 3, which I don’t understand—I just accept it, in hopes that they’ll accept my desktop choices in return.

Flash : there is also gecko-mediaplayer as package .. and there are helper firefox-addons like flashvideoreplacer .. or you can change quality to make it run fast. Quote:

@daemonfowl
@backrow As I mentioned things that I will miss on OpenBSD after a migration from FreeBSD, there are several things about OpenBSD that I miss in FreeBSD ... - OpenBSD's focus on implementing proper and *working* suspend/resume [1] - OpenBSD's developers attitude, while OpenBSD developers actually use OpenBSD for their laptops/workstations and so, FreeBSD developers tend to use Macs/Macbooks for their workplace instead of FreeBSD and that is quite hypocrisy I must say :/ - OpenBSD team ported/implemented GEM/KMS a lot faster then FreeBSD team - OpenBSD work on wireless drivers is impressive - OpenBSD's 'software stack' - PF/OpenSSH/OpenSSL/OpenSMTPd/... - lots of great stuff. [1] from FreeBSD 9.0 and later suspend/resume also works, but it worked a lot earlier and better on OpenBSD

If freezing is symptomatic of bad OS performance then I'd say : OpenBSD almost never freezes on this laptop , while I use it at times as a full desktop (gnome/kde) with lost of GUI applications running at the same time .. this was not the case with PcBSD.On a 8 giga flash stick OpenBSD installs & runs well ! when I first tried installing PcBSD on that very stick it installed but hang on boot and never got on to fancy Kde4.
Is this Equation correct? Security/Reliability + Usability = Good Performance. Doesn't it lack a human factor : one's ego : me .. me .. me ? What I'd be using/expecting .. Doesn't it lack a machine factor : the hardware with all its + & - ? AMD 64 intel athlon ppc .. I used httrack to mirror big edu sites once on Windows : Fiasco , as data size gets bigger & you can't do extra tasks with ease.In OpenBSD : I was on fvwm , httrack xterms filled 3 to 4 screens : that makes : 12 mirroring instances for days .. It never froze. Good Performance : offering maximum functionality with minimal/zero undesirable consequences.On Compaq Mini CQ10-130SE : Win** overheats machine while boastfully serving you a Gui+IE.This was not the case with NetBSD/OpenBSD : they serve X + full unix functionality that a Unix average user would expect using .. this without smothering the machine.

Performance is a measurement of various rates, eg. how many transactions can a database handle per minute, how many requests can a Web server handle per minute, etc. Doing some basic research is in order. Wikipedia's entry is a start: http://en.wikipedia.org/wiki/Computer_performance |

The practice of developing enhancements directly on the targeted operating system is preferable as it can expose bugs masked in other environments. The practice is known as "eating your own dogfood". Quote:
The only time such practices are valid is when all customers will be using the developed product in the same environment. If any aren't, then thorough testing needs to be taking place in the environment in which the developed product will be used. |

Also, VMware Fusion being better then VirtualBox on FreeBSD? Let them make VirtualBox better then ... its also open-source. What about FreeBSD Jails, they are useless for development then?

Thank you @ocicat for schooling us & for the always useful information you supply!
Thank you @vermaden for sharing ideas and allowing us to ! & sorry to both for being shallow , it's but an amateur's feedback not a technician. Software Quality : OpenBSD does better than the rest --> least buggy OS ! Ubuntu is for humans , easy & pop ya , but the more you install on it the buggier it gets.Try installing as much packages on OpenBSD and compare ! they never undermine the OS stability. (again my shallow feedback) |

worry not, sir
worry not sir, as OpenSMTPD has been ported to FreeBSD (and NetBSD/dragonflyBSD,Linux,MacOSX) ;-)
