I've never found Slackware to be hard to update packages. If the latest version of software isn't in the package browser, you can either make a Slackbuild file, or compile it yourself and use checkinstall to make a package, (which is actually easier than making an ebuild file) I've never experienced "dependency hell" on Slackware... On RPM distros, when using unofficial packages, yes, but not otherwise.
Thats great. I never used Slack before and dont know where this big defense in the name of S came from...actually I havent even seen Slack being mentionned in this thread...
I had talked about it above. I was just pointing out there are some binary distros that aren't bad in updating :)

We are only on page 2 of this thread and yet I have identified a lot of new material for http://www.funroll-loops.org. Niot that it is my site, but I'm sure the maintainer is going to read this thread.

Frankly, I don't care much if it is faster than distro X. That is a very secondary issue. I primarily use Gentoo because of Portage, the ability to test and fix programs that are not running or compile as expected on my AMD64 system and because of the community, i.e these forums.

Also be aware of the fact that one set of CFLAGS does not necessarily produce faster code with all programs. Best advise is to select a standard set of CFLAGS and stick to them.

Want speed? Use prelinking.

Quite...

Come on people... you're making all of us look stupid.

Yes, out of the box Gentoo will be a tiny bit faster than Redhat or Mandrake or Suse or whatever, because you tweaked your CFLAGS and set the right arch. Is the performance difference noticeable? Is it really? I'd like to see some benchmarks on how much faster Gentoo is than Fedora or whatever, because frankly I think the performance difference is negligible.

And once you get beyond the "out of the box" stage any distro can be as fast as any other. You can rebuild RPMs in Fedora for your arch. You can compile everything from source with your CFLAGS and settings in Debian. You can even - believe it or not - choose exactly what services you want running if you fiddle about a bit.

The strengths of Gentoo are Portage and the use flags system. That said, even portage has its caveats and there are other things like apt-get which are pretty damn brilliant; and I'm sure you could find a way to do the same thing that use flags do in other distros when compiling from source just by setting the right options in your configure command.

I've got to the point where I don't use Gentoo because it's "so much faster" or some rubbish. I use it because, for me, it's easy. I know my way around and I know how to use it, same as other people know their way around Redhat or Debian or whatever.

Last December I went Mandrake -> Gentoo and I noticed a huge speed increase. Then I went from ext3 -> reiserfs a while back and noticed an even greater speed increase with the same system since I just copied the install back and forth between partitions. ReiserFS+Gentoo == steam rolling. 8)

I call this BS unless you have numbers to back it up with.

What exactly is faster? How much faster?
What are you doing that makes reiser give you better performance and how much?

Numbers please!

Keep in mind that performance improvements might be hard to detect on a fast system. Also, how do you measure desktop responsiveness?

Like I stated before, I installed gentoo on my mom's comp, which isnt exactly a speed demon. There I really noticed a difference. But I dont know how you would measure that, since firefox kde and openoffice dont have any option to display fps. :wink:

I guess you could benchmark load times, but I dont think load times are necessarily a accurate benchmark.

Allthough it would be interesting to see some benchmarks with stuff like encoding or rendering. But I think the scope of a accurate benchmark is beyond the average user. Would probably be a job for Tom's Hardware Guide.

Hi,

When I installed FreeBSD, I noticed a performance improvement (faster startup/shutdown time) and faster compilation times than Debian. FreeBSD does use a small sh implementation (and not a symlink to bash like Debian and Gentoo) which might explains part of this speed?

Between Debian and Gentoo, I don't notice any difference.

I used Gentoo for flexibility, good development platforms, etc.

Gentoo is definitely much faster and responsive than Mac OS X.

I started this thread http://www.linuxquestions.org/questions ... did=267842 over at linuxquestions, since I noticed such a huge difference between gentoo and my previous distro, debian. I naturally thought it was due to the USE-flags, etc, since I had my own kernel when using debian as well. However, the folks over at linuxquestions.org had me (almost) change my mind, and right now I don't know why debian was so much slower than gentoo. I haven't had a chance to reinstall debian yet though.

Last December I went Mandrake -> Gentoo and I noticed a huge speed increase. Then I went from ext3 -> reiserfs a while back and noticed an even greater speed increase with the same system since I just copied the install back and forth between partitions. ReiserFS+Gentoo == steam rolling. Cool
I went from reiserfs -> xfs on my largest partition (~200GB); and that was some increase in speed as well. Haven't tried Reiser4 though. Rumor says its speedier than speedy :)

What is the difference between stage 1 and stage 2 and 3 install. IS it speed or something else?

strictly speaking; no, it's definitely not speed. The higher the stage, the larger amount of the gentoo is already compiled for you. What you miss out on if you start from stage 3 is the privilege to compile what has already been compiled, with the optimizations you prefer. On the other hand, if you start with stage 1 you miss out on.. well.. a lot of time, as a stage 1 install takes significantly longer time to be completed.

Will you gain speed if you have your own optimizations? Not necessarily, but perhaps. It depends on so many factors; search the pages here and read the debates...

When I switched to Gentoo from Fedora, I noticed a lot nicer I/O usage (probably due to using the 2.6 kernel on Gentoo and a heavily-patched 2.4 kernel on Fedora). I also tried installing on ReiserFS but that didn't seem to give me any significant improvements in speed over my tweaked Ext3 partitions. The fact that had a ReiserFS install before that fail and some of what I've read Hans post to the LKML has definitely pushed me away from Namesys's filesystems...

really? like what?

on another note, I think the biggest speedboosts come from nptl-enabled 2.6-kernels and -march=i686 (of course -march=pentium4 results in speedier binaries than -march=i686 would for a p4-system; but, nevertheless, the biggest step in speed improvement is probably from i386 to i686; i686 to pentium4 is will make a smaller difference). I've been running archlinux for a while now (i686-compiled) and it definitely feels as speedy as any gentoo variant I've managed to pull out of my gnu compiler :)

No, I didn't find Gentoo significantly faster than Suse 9, which was the distribution I used before it. Of course it boots faster, but that's just about it.

I find Gentoo to be slightly faster than binary distros. Having used SuSE mostly (I still have SuSE 9.3 on my laptop) I find binary distros seem to slow down after the initial load and with subsequent upgrading, while Gentoo does not. It seems to hold that "fresh install" feeling. But I agree with ChrisWhite, I'm using Gentoo for the choices, and the package management, not the speed. I wanted a distro I could install, and evolve, and not have the binary distro cycle of install and reinstall. Gentoo gives me precisely what I want.

There's been nothing in this thread to say that Gentoo is truly faster that any other distribution out there. I think that some of you guys may be fooling yourself into thinking that your computer is running any faster. Maybe you have though. Go ahead and post some numbers and maybe then I'll start believing all of nonsense in this thread. It doesn't even have to be a real benchmark, even if you did it with your pocket watch I'll believe it. Let's just see some numbers.

Everything is faster if you want it to be. Most people are falling into the placebo effect. I had a buddy who swears that (and has others agreeing) when he washes his car, it runs better and smoother.

I know there are some that feel the same way. Just another example of people making things better and faster just by mere perception. What is the difference walking in a room, having half the room bust out laughing and thinking: a) they are all laughing at me or b) noticing The Simpsons are playing on the tv just above you...

In a bad mood the entire world is miserable and treats you like crap (how many have had bad experience after bad experience making you say "I wish I stayed in bed today" and when you are in a good mood, then the world is all sunshine and bubblegum...perception is certainly a powerful thing.

As ebrostig, you gotta throw up some numbers or you are just all this speed just might be in your head.

Yeah, that classic one is *really* funny. I wonder what the guy was thinking. I mean, he must've worked hard to find the existence of those flags, so why didn't he check out what they actually do to your system...

anyway, I haven't seen anything ever boot as fast as Arch does. It's really amazing. And that speed has nothing - or very little - to do with how binaries are compiled, it only has to do with how the distro handles startup scripts.

I still think any binary distro aiming for the desktop should compile all binaries with -march=i686 (and possibly mcpu=pentium4)...

If it seems slightly faster to me, then it is. No one else matters... A perception doesn't require benchmarks to be valid. Now an official claim would be another matter, but I at least, didn't make one. Now if someone wanted to provide benchmarks, I wouldn't be against it, but I'd use Gentoo anyway, regardless of the tests. I'm in it for the package manager...

So is it possible, that you know, how much speed ca your computer gain, or is it already gained all the speed that can be? Is there any chance to try to improve speed? Just a thought!

I voted "significantly faster" only because it is so much fater than most of what is out htere. My old distro was slack. I guess my Yugo had a v12! Vroom and VROOOOOOOOM! But seriously, it's nicing having a little extra spunk in your OS, but what is really good is the integration in Gentoo.

How can anyone claim that their distribution is faster than another without defining what "fast" means? Do certain graphical applications actually launch faster, database queries complete more quickly, your system crashes in a hurry because of the retarded CFLAGS that you've used? What are you people talking about?

It's faster, used to run Slackware before. And since Gentoo is totaly optimized for my pc-hardware, it should be faster than any other distro :D .
