Alternative Performance Kernel for Debian
Re: Alternative Performance Kernel for Debian
After that stoush I just had to try it.
Very nice work damentz.

Re: Alternative Performance Kernel for Debian
Do you realize that the "stoush" was about Con Kolivas' BFS scheduler? Do you realize that the version that you tried does NOT use the BFS scheduler? All you tried was a collection of patches to the standard kernel.sir fer wrote:After that stoush I just had to try it.
I do not object to the distribution of a kernel with an untested scheduler, so long as the user is warned that the scheduler is untested.
Damentz did not provide any such warnings however. Instead he claimed that:
Such statements are completely irresponsible and I strongly object to his actions.damentz wrote: BFS is very stable

Re: Alternative Performance Kernel for Debian
Settle petal, yes I realise all that...
It was the first i'd even heard of the liquorix kernel so I would have tried it no matter what
thanks for the link re:BFS tho

Re: Alternative Performance Kernel for Debian
I tried this kernel the other day. One thing I didn't understand: I added a deb-src line and downloaded the source so could change the arch and remove some crap that I knew I wouldn't need and didn't want to have loaded (ipv6, bluetooth, webcam driver, etc), and menuconfig showed the timer frequency at 250 MHz.
Re: Alternative Performance Kernel for Debian
The timer is set to 864hz, you didn't apply the patch set to your standard kernel in order to have access to the hundreds of extra kernel options you can fiddle withdbbolton wrote:I tried this kernel the other day.

I created a sources folder at http://liquorix.net/sources . You can check the raw configuration and you should get identical results compared with this:
Code: Select all
$ cat /boot/config-2.6.31-0.dmz.8-liquorix-amd64 | grep CONFIG_HZ
# CONFIG_HZ_100 is not set
# CONFIG_HZ_108 is not set
# CONFIG_HZ_144 is not set
# CONFIG_HZ_216 is not set
# CONFIG_HZ_250 is not set
# CONFIG_HZ_300 is not set
# CONFIG_HZ_432 is not set
CONFIG_HZ_864=y
# CONFIG_HZ_1000 is not set
CONFIG_HZ=864

Re: Alternative Performance Kernel for Debian
Well I tried the liquorix kernel and then my goldfish died so I removed it.
Actually it works fine although I don't notice any obvious performance gains. I don't run alot of services on boot and don't use KDE either (which when compared to LXDE takes days and days to load). Everything is crisp and snappy but this is all just user perception.

Re: Alternative Performance Kernel for Debian
Actually this is a misunderstanding, a new scheduler (especially one focused on the desktop) won't make programs start faster (they actually might even slow down) the purpose of such scheduler is to make the whole experience smoother and the computer more responsive which in some cases reduces the actual performance of some pieces of software.mzilikazi wrote:Well I tried the liquorix kernel and then my goldfish died so I removed it.

Ubuntu hate is a mental derangement.
Re: Alternative Performance Kernel for Debian
Ah, but more than the scheduler is tweaked here - BFQ is used as the disk scheduler with a patch to drain the NCQ queue on the disk hardware, reducing sync latencies that most desktop applications need to stay responsive during high disk load.AdrianTM wrote:Actually this is a misunderstanding, a new scheduler (especially one focused on the desktop) won't make programs start faster (they actually might even slow down) the purpose of such scheduler is to make the whole experience smoother and the computer more responsive which in some cases reduces the actual performance of some pieces of software.
That could be it, just a guess.

Re: Alternative Performance Kernel for Debian
If anyone else is interested in particular configuration differences between the standard Debian kernel and damentz's Liquorix kernel, here's a side-by-side comparison of the respective .config files (generated with 'comm' and 'sort', as I find large diffs to be annoying to read) --
http://pastebin.com/f6205cdfb
Please note that I was using the .config file for the Debian 2.6.30 kernel currently in testing, so some things may not be a true apples-to-apples comparison.

Re: Alternative Performance Kernel for Debian
I've install your liquorix kernel, but I'm still only able to get 2D with the fglrx-driver. Is it still not able to get 3D?
I removed xserver-xorg-core, installed flgrx-driver and fglrx-control then ran aticonfig --intial.
Thanks for any help

Re: Alternative Performance Kernel for Debian
I don't think fglrx has ever supported the newest stable kernel before - try the version from my past branch; instructions to accessing that branch are on a blog post of mine here -> http://transient-inode.blogspot.com/200 ... es_20.html
Phoronix' forums may have something, but it takes work to sift through all the noise (FUD and just angry postings with no substance) to find the patches.

Re: Alternative Performance Kernel for Debian
Great job damentz on your kernels and I know you don't ever let your userbase down. If I find a problem I'd let you know and from your track record you resolved the issues.
As for all the attacks on damentz, I feel they are totally unwarranted and the admin agrees with this.

He removed the objectionable material and then he used a hot-linked image to insert profanity into my post:
EDIT and UPDATE: And then he switched the image back to cover his tracks.

Re: Alternative Performance Kernel for Debian
sidux is Debian sid with a better (actually questionable according to what you prefer) default configuration and package selection with the desktop user in mind. The developers also try to temporarily fix packages that arrive in debian Sid which might have broken many of their user's installations.gnudude wrote:sidux isnt sid....DeepDayze wrote: Debian Sid user here
What you asserted it similar to saying, Linux Mint is not Ubuntu, although with a few commands with apt-get, and a few gtkrc theme modifications, you will be using stock Ubuntu.
The trick is that both of those distributions depend highly on their distribution base's repository always functioning and doing the work for them - they just change some cosmetics, default configuration, and default package selection.
Re: Alternative Performance Kernel for Debian
hey if you want to dance off topic then lets do a jig...
sidux is based on debian sid....sidux is debian sid based...sidux is binary compatible with sid....but sidux is not sid....
I guess linspire is also debian sid....xandros.....ubuntu....all debian sid....and...well....everything is debian sid....glad we cleared that up...
uh no....sidux doesn't even use a debian kernel but rather their own kernel...and you aren't suppose to use some tools that debian specifically suggests to use...no dfsg...etc....sidux is Debian sid
sidux is based on debian sid....sidux is debian sid based...sidux is binary compatible with sid....but sidux is not sid....
that would make it NOT sid then...right...The developers also try to temporarily fix packages that arrive in debian Sid
actually clem uses a number of specific tools that he has wrote for mint....but who is talking about mint...similar to saying, Linux Mint is not Ubuntu
I guess linspire is also debian sid....xandros.....ubuntu....all debian sid....and...well....everything is debian sid....glad we cleared that up...
