Four Flat Tires: Accelerated Knoppix

Distrowatch says, "Japan's Alpha Systems has released Accelerated KNOPPIX 1.0, a fast-booting variant of the popular KNOPPIX live CD. By re-arranging the Cloop file system block and optimising the hardware detection and configuration step, the developers have succeeded in reducing the CD boot time to under 60 seconds, while maintaining the full functionality of the distribution. More details with illustrations of the technology" on their site. Whoohoo. To quote a famous American actor, "I feel the need, the need for speed!"

Before there was Super, before there was tuxmachines.org, even before there was PCLinuxOS, a good friend and I were always on the lookout for new techniques and methods for speeding up our systems. He was better at it than I, which is why he has his own distro now while I'm testing other's. But from parallel boot, compile options, to pre-linking, we would try about anything and send each other the results. When I saw the announcement for Accelerated Knoppix, I felt that old excitement rush back. Too bad it was short-lived.

My hardware is not exotic or bleeding-edge. It consists of a single-core 32-bit AMD Barton XP 2800+ sitting on a MSI KT4AV with 1 gig of Kingston ddr400 ecc ram. My add-in cards include a sound blaster live 5.1, BMG nvidia 6800oc video card, and a Prolink pixelview tv/radio card. My drives are your basic run-of-the-mill ata.

The boot screen has a customized splash with the instructions to use F2 and F3 for booting options. The only option I chose was lang=us and started timing when I hit enter. It took 2 1/2 minutes to get to a wallpapered background and hear the familiar knoppix, "Initiating Start Sequence" announcement. It took 6 more minutes before KDE was fully up and usable. Clicking on the Kmenu button took another 30 to 45 seconds before the menu appeared.

        

        

Having the wind taken out of my sails, I looked around just a bit. As you can see Accelerated Knoppix places icons on the desktop for each and every device it finds. There was no turning them off as it apparently isn't a kde function on their desktop. The menus seem chocked full of applications, but the menu was slow to respond and what I can only describe as "jerky" in operation. Applications were slow to open as well. Otherwise it seemed pretty much like the standard Knoppix fare to me.

        

        

There appears to be some documentation included in an Accelerated Knoppix folder on the desktop containing scripts that open pdf files probably describing some of their methods and techniques in Japanese. I had big plans of investigating and reporting on this topic, but with such poor performance, I lost interest. I have requests out to a few friends to test and will update this report if they have better luck. If you test and have better luck, please feel free to post. Perhaps there is something about my hardware with which Accelerated Knoppix had trouble. But for me in my mind, they still have work to do before this distro satisfies my deep seeded need for speed.

Speed of automobiles depends on weight carried ?

If I were to cheat; I would shed some weight; reduce frontal resistance and avoid drag; but that is my automobile design with a bigger engine and runs on nitro gas.

The speed of a computer using Knoppix accelerated, depends on the certified computer components(533DDR instead of 400). Did they use dual core Intel cpu same as Apple is using for four times the speed of G5 PowerPC??? Then they lighten the load with barebone architecture???? It is tricky to build speed equipment, hot rodding with bloated Knoppix kernels and KDE modules.

Old Puppy(based on Mandrake 9.2) used to boot in 6 seconds(vesa, busybox and a few legacy universal drivers not used), not counting the time to load its iso into ramdisks. So, cheer up and ask a few questions in Japanese, "what's the secret?". Is it installing USB equipment after you boot?

Something is wrong here...

srlinuxx,

My experience with Accelerated Knoppix is that it is the first fully-loaded live-distro that is usable directly from the CD. Even application launch times are acceptable.

I've used Accelerated Knoppix on 3 machines so far, all intel: Celeron PIII 400Mhz, Celeron P4 1400Mhz, and a P4 2400Mhz. Even the PIII Celeron 400Mhz boots into KDE in about 2min-30sec.

The system that is probably close to yours is:
P4 2400Mhz, 512KB cache, 1GB PC2700 DDR, Nvidia GeForce FX 5200.

I did some lazy benchmarks of Accelerated Knoppix vs. Standard Knoppix 4.02
For CD:
boot>knoppix lang=en nodhcp dma noddc screen=1280x1024 vsync=60
For HD iso image:
boot>knoppix lang=en nodhcp dma noddc screen=1280x1024 vsync=60 bootfrom=/dev/hdb1/ACC.iso (or KNO.iso)

Boot times into KDE desktop for each configuration
--------------------------------------------------
Accelerated Knoppix: 0:55 from CD , 0:45 from harddrive .iso
Knoppix 4.0.2 : 2:10 from CD , 1:05 from harddrive .iso

As you can see, booting from Accelerated Knoppix from CD is faster that booting Knoppix 4.0.2 from the .iso file on the hard drive!

I really think that your issue is most likely NOT with Acc-Knoppix. I think you have a high error rate disk, a disk drive problem, burned the disk in a mode that scrambled the files (use dao or sao), or have a machine that doesn't work with Knoppix.

I would suggest
1) Make a new burn on a quality drive with quality media at low speed using a disk or session at once mode. (NO CDRW media, use shiny CDR)
2) verify the burn if possible (cat /dev/hdc > run_md5_on_me.iso)
3) make sure that you use the dma option at boot>
4) Look into the knoppix bios workarounds if this is the problem.
5) Use bootfrom= option to check if the problem is your CD drive.
6) Boot regular Knoppix4.0.2 on your machine.
7) Try another computer or CD drive.

I think you may have been too quick in blaming the distro for poor boot times. Or maybe you have an irresolvable hardware/distro incompatibility. It would be nice to know why you had such bizarre slowness.

nodhcp noddc in cheat codes ?

How much time difference, if dhcp and ddc are booted? Do you have to specify dma to have it active?

Have you tried AMD cpus; I noticed that all your computers are Intel cpu based, which has less L1 and L2 cache for long instructions? In booting process, large L2 cache may be a hinderence, because its mostly data transfer; in computation of logic, large L2 cache will gain speed over smaller L2 cache by 20%. Also the number of stages in the pipline for branching prediction used by different cpu makes a difference in speed if you fine tune codes to fit each clock execution within the memory assigned.

ie., Linspire(Knoppix based Sarge) is extremely slow with 128 mb of dram, because of hdd swap file being used, but not fine tuned(Toram option would be better in speed). Speed is very good if 256 mb of dram is used, which is the default requirement, meaning optimized. Knoppix 4.01 toram option has to be used to be fair. Same with Accelerated Knoppix.

Re: nodhcp noddc in cheat codes ?

nodhcp noddc screen= ... these are just the cheat codes I normally use with knoppix based distros, I included them above for full disclosure. I doubt these codes would make any difference (other codes might). It seems that dma is on by default in this distro, but I just include it since DamnSmall defaults to off.

The systems I have access to are all Intel, and I included my basic benchmarks on the system that most resembles the author's in horsepower and configuration. My larger point is that even my 400Mhz | 128K cache | 192M Memory | Intel Celeron boots into the KDE desktop in 2min 30sec. I just think there is somthing fundamentally off with the author's 8min 30sec. This is very very wrong and needs and explaination.

I suspect that the author's drive is running into a lot of failed reads that get re-read and error corrected. It could be the burn, it could be the drive, or something else entirely. I wouldn't jump to bashing the distro so quickly.

Using the bootfrom= option is a great way to try out knoppix distros without the "klunky", mind melting slowness of most live distros. Application launch is faster than even my Gentoo Box(what I normally use). But Accelerated Knoppix is really just fine from the CD, just a bit slow in spots. If I had to take a live distro to a friend's computer to show them linux, it would be this one.

I think it is just premature for the srlinuxx to declare that Accelerated Knoppix has "Four Flat Tires" when maybe the driver just drank four "Flat Tire" beers.

I booted with boot>knoppix lang=en ...

Forgot to type the knoppix option in my post below. FYI.
