Is that in Spanish?

It looks like a speed-comparison. If that's right it looks comparable to my own speed-tests (done with a stopwatch).
Arch is a great system, but Debian is faster in some occasions.

Oh God that hurt to say out loud.

Re: Comparative debian centos arch

As much as I at one time liked GNU/Linux Debian... Debian is released slowly, once every 1 to 3 years is an offical stable release available, and quickly goes out of date, and sometimes updated packages just are a no-show in the repositories.

* The software used in the tests marked outside time, but Arch continued processing until it finished, about 5 minutes later.

In relation to the test of dynamic apache Arch Linux: I have investigated a little, and would say that it makes very aggressive use of the ram, obtaining spectacular results while there is memory available, but stumbling when there is use of swap.

Re: Comparative debian centos arch

Isn't Debian build for i386.  Surely we don't get negative optimization going to i686....

Anybody have a Debian install along side their Arch and want to do a comparison?

Re: Comparative debian centos arch

Iirc Debian is optimized for i686, too. But they use GCC snapshots and iirc some custom C(XX)flags.
Maybe Arch could also use some?
like -march=core2 -mtune=generic ;P

I myself built KDE(mod) and QT from source with custom Cflags and LDFLAGS and it starts much faster now.

Thanks for the translation.

Something is slowing Arch down, and yes Debian is build for i386, well actually i486. Kernels is about the only thing they do build with optimizations.

It's not the same thing (I know), but still usefull in this context I think.
Some startup-times: (time was taken with a stopwatch)
Arch GRUB -> CLI "login"
First boot after clean install (2007.08-2 CD) 18 sec
After update 21 sec

Debian GRUB -> CLI "login"
First boot after clean install (Etch 4.0r0) 17 sec
After update 17-18 sec

Arch
GRUB -> GDM (with theme) 29 sec
GRUB -> GDM (simple - default) 31 sec
GRUB -> KDM 30 sec
GRUB -> SLiM 27 sec

Debian
GRUB -> GDM (with theme) 27-28 sec
GRUB -> GDM (simple) 27-28 sec
GRUB -> KDM (with theme) 30-32 sec
GRUB -> KDM (no theme) 26 sec

All done on the same system, clean install.
The times may get better when the new initscripts comes. But not for certain.

some tests shows arch is not so good as debian and Centos

maybe that is what arch can change , just because gcc slows down ?

in fact , i realy dont know which is faster, just because i have used ubuntu before ,and i feel ubuntu is slower than arch ,so ..

Debian *feels* faster and is, but it did never boot as fast as my Arch Linux.

Ubuntu IS slow.

Just because it's based on Debian, doesn't mean it is Debian, because Ubuntu is NOT Debian. The same concept goes for any other distro based upon another.

Re: Comparative debian centos arch

Isn't it possible that some hdparm settings is better on the debian and centos system used for the benchmark?

Re: Comparative debian centos arch

debian is definitely very fast, but to me arch still seems faster. I don't have X on my debian machine, so it's hard to do 1 to 1 comparison with a gui, but subjectively arch feels faster. it definitely boots faster as buddabrod said.

of course, any improvements arch could make would make it seem even MORE faster.

>>I'm surprised CentOS is so fast. I was thinking of replacing debian on my server with centos just to check it out, but I thought it would probably be a lot slower and more bloated, so why bother with all the extra work it would take to switch. now I'm having second thoughts!

Re: Comparative debian centos arch

I'm assuming that this results are genuine.  My guess, however, would be that the differences have less to do with distros used and are a function of the kernel that's used in each.  I remember reading a benchmark comparing FreeBSD to Linux kernels (see this, for example) and the interesting part was that the 2.6.22 kernel was, on average, a noticeably better performer than more recent kernels -- which is probably due to the fact that the newly introduced CFS scheduler is not yet fully optimized for performance.  Of course this is likely to change in the future as the new scheduler matures.

If you want your system with X boot faster, use evdev for mouse and keyboard. It doesnt sleep for several seconds before starting up ;P

Got the same spectrum of results when I compared arch against debian i386 in a blender benchmark.

Re: Comparative debian centos arch

So - why is Arch comparably slower than Debian, despite being labeled as very light-weight (which does not necessarily apply to Debian)?

Re: Comparative debian centos arch

Wild guess. But debian's huge userbase helps it package some stuff into more modules. eg. Haskell's libraries.

But that is a lame excuse. Read that comparison again and you will find Arch beats it in many places too! Check all the dynamic apache shootouts, mencoder. Also make can take different times to run depending on certain factors, like startup delay! I don't use much of perl other than the core stuff that needs perl. And arch definitely feels faster on my PC.

Debian seems to boot way slower than arch. For me, arch boots in say 11 seconds. Deb takes some 18 seconds

Re: Comparative debian centos arch

My debian install (partition with Arch on the same machine) starts up some apps faster first time around (eg OOo etc.) and is definitely a speed demon - but boots waaaaay slower than Arch - sometimes its like waiting for a bus. If anyone wants any tests running (logs etc. - I dunno, just a guess) then just shout.

A few numbers would be nice, if you have the time to spare... Sometimes it's hard to tell if it really is faster or it's just our brain tricking us...

Re: Comparative debian centos arch

Are there any terminal commands that measure startup speeds for apps? if not, I'll dig out a trusty stopwatch!
Any suggestions for things to test?
I'll do boot, time from grub-gdm-desktop etc. startup for major apps (Ooo, Firefox, Gimp etc.)
Any others?

Re: Comparative debian centos arch

Ok folks - here are the results of my extremely unscientific tests...

This is on a 1G ram, dual core Tecra A8 - both setups are using compiz and preload, both booting to GDM and Gnome.

Time from Grub to GDM: Arch 32 secs / Debian 57 secs
Time from GDM to desktop: 23 / 38
Time to shutdown: 14 / 28

Cold start (hot in brackets) - OOo-Writer: 9.5 (1.2) / 8 (1.5)
Firefox/IceWeasel: 5.2 (4.8) / 10 (4.5)
Gimp: 5 (3) / 8 (2)
Epiphany 4.2 (1.8) / 2.7 (1)
VLC: 1 (instant) / 2 (instant)
Exaile: 4.5 (2) / 4.5 (1.5)
Terminal: 1.2 (instant) / 1.2 (instant)

And the winner is....

Booting etc. = clearly Arch by a mile
Cold starts: Arch 3, Debian 2
Hot starts: Arch 1, Debian 4

So there we have it - conclusive proof if ever there was any that I have way too much time on my hands!
