I've run GtkPerf 100s of times, and never seen a difference of this magnitude!

Jaw-dropping difference, actually... o_O

I noticed it's got the "200 line patch", so called, in it. That's cool!

Yes, it does. Even Linus likes this patch:

Alrighty then...

Less than 24 hours, and I was greeted with a (Liquorix) update already!

All hail, Linux 2.6.36-3.dmz.2-liquorix-686

Yes, he updates quite often. Unless there is a bug fix, security update and something you need. You should not need to update often. Once a week or two is a good compromise I think.

I was looking at his pool, and evidently the last build was 10 days ago, so that's not too 'bad'.

SOURCE: http://liquorix.net/debian/pool/main/l/linux-liquorix-2.6/


Then, I checked his future (experimental) pool.

SOURCE: http://liquorix.net/debian/pool/future/l/linux-liquorix-2.6/


OMG! He just added 2.6.37 -- which I've been lusting for...

Soooo, I added his 'future' repo to my sources list and installed 2.6.37.

It would appear that you've created a monster! LoL! :D

Heh! This is where the 'trust issue' crops up for me.

Supposedly, Debian 'experimental' kernels are more stable than most 'stable' kernels in other distros.

Time will tell... ;)

Regular ol' Intel P4 S478s are going for $5-15. Maybe that's what you're thinking about...

I've never seen an Intel SL7CH for less than $100. ;)

No, I know exactly what CPU I'm talking about. It's still a single core(pre Prescott) 32-bit processor w/ only 2MB of cache. It's hot and slow. Just because it's listed at a high price doesn't mean it's selling for that price, it barely looks like there is even a market for these chips given that you could only pull up one listing on e-bay.

Vindsl .... yeah so what some chumps buy p4 in 2011. The reality is for $100 you can get mobo combo deal and be better off.

Honestly this is a hardware enthusiast forum. Saying a p4 anything is worth more than a current Gen CPU that
performs better is silly.

So yeah, I've been running the kernel so far doing all of my typical stuff and it's great. I can't tell if its faster, but it definitely shuts down faster in Ubuntu 10.10 for me. Looks like VinDSL's post shows a big performance upgrade in a lot of aspects, right? :)

Hrm... Chicken n' egg scenario.

I noticed that the Gnome Sensor App isn't reporting THRM (CPU temp) values...

Doing a little Google'ing, it would appear that 2.6.37 is addressing some ACPI issues, et cetera -- to make Linux come out of a hibernation/sleep state more reliably.

Or, maybe the panel apps simply haven't caught up with changes to the ACPI code in 2.6.37 yet.

Other than that, everything seems to be working fine! ;)

Amazing, isn't it?!?!?!?

Heh! 10.10 shuts down shockingly F-A-S-T now!!!

I'm still getting 24 second boots, so that hasn't changed, for better or worse...

Yeah, lots of good results so far. Good thing I brought this up, right? :D

Gotta say, if it wasn't for gaming, I'd be running the world's oldest hardware ever. In fact, I'm running Ubu 10.10 with the Liquorix kernel on this single core AMD laptop and it does everything perfect.

I went back to Debian kernels. I made some changes to my network and ran some tests with iperf to check my work. When using 2.6.36-3.dmz.[1-2]-liquorix-amd64, was getting ~240-280 Mbits/sec. This was low, since previous tests showed the speed being much faster than that. So after trying different cables and bypassing the switch was still getting slow speeds.

The only other thing I had done since the previous test, was using the liquorix kernel. Booted into the Debian kernel and ran the test again, now was getting similar speeds like before ~940-970 Mbits/sec.

Yeppers!

I've been running 2.6.36-3 mostly. It works flawlessly!

2.6.37-0 is okay too, but the lack of THRM (CPU temp) in my Gnome Panel is bugging me...

what does zcat /proc/config.gz | grep ACPI_PROCFS say ? It could be that liquorix maintainer evicted deprecated /proc/acpi files counting on a new userspace to pick up the changes already.

Since this has been working out so well... :D

I thought I should clarify a few things.

As of today, here are the Lixuorix maintainer's pool:


These links allow a quick peek at what's being offered in the repos.


To reiterate the install:

Code: 
sudo echo "deb http://liquorix.net/debian sid main" > /etc/apt/sources.list.d/liquorix.list
Code: 
sudo apt-get update
Code: 
sudo apt-get install '^liquorix-([^-]+-)?keyring.?'
Code: 
sudo apt-get install '.*liquorix'

That's it...

Here are the Liquorix entries I use in my sources.list:

Code: 
<snip>

deb http://liquorix.net/debian sid main #Liquorix Kernel
deb-src http://liquorix.net/debian sid main #Liquorix Kernel Source
# deb http://liquorix.net/debian sid main future #Liquorix Experimental Kernel
# deb-src http://liquorix.net/debian sid main future #Liquorix Experimental Kernel Source

</snip>

The Future repo is currently inactive...

Ubu 'Update Mangler' won't catch the changes (obviously) so I watch the links (above) and use Synaptic to update. ;)

Yea, running on the 2.6.37 liquorix kernel here now and I also attest to the amazing stability and snappiness of this kernel. The only issue I have with it is the Hauppauge 950Q tv usb dongle I have no longer works with Tvtime, but I think thats a linuxtv issue as I think they still have yet to catch up with dvb fixes for the newer kernels.

So, I recently upgraded to the most up to date Liquorix kernel and it turns out, the ATI Drivers that were installed seem to be having trouble with it. Nothing is wrong, but the way things "pop up" or "render" are awkward now, and I did some reading on the internet and it seems the new kernel works too well with ATI FGRLX or whatever it's called. I read that this is the fix, but I have no idea what it means :)

http://www.webupd8.org/2011/03/how-to-install-liquorix-kernel-in.html

It says to install a script into /tmp, then switch to a TTY, etc. on the bottom. What the heck does that mean/do? I want my graphics to work properly again :(
