CD boot time of KNOPPIX shortens by "LCAT"

[Kenji Kitagawa]

In order to decrease the boot duration, we have customized KNOPPIX.
and named "Accelerated-KNOPPIX".
http://www.alpha.co.jp/ac-knoppix/index_en.html

Accelerated-KNOPPIX1.0 is based on KNOPPIX4.02 Japanese version.
We managed to boost the performance by using LCAT package and boot duration
has been shortened by half.
http://sourceforge.jp/projects/lcat/

Now, We have customized KNOPPIX 5.0.1 English version released on the 2nd of June 2006.
http://prdownloads.sourceforge.jp/lcat/20452/KNOPPIX_V5.0.1_20060602EN_Accelerated.iso.torrent

Each boot time is about half time as follows.

PC1:Panasonic Let's Note W2
CPU:Pentium M 900MHz MEM:512MB CD-Drive:24x
140sec --------> 59sec

PC2:SHARP MURAMASA
CPU:Pentium M 1.6GHz MEM:1GB CD-Drive:24x
170sec --------> 97sec


Please refer to the manual (English version) for the method of speed-up by LCAT.

We hope that the LCAT package will be included in the main stream.

Hello,

I compared boot time of Original KNOPPIX 5.0.1 CD and Accelerated KNOPPIX 5.0.1 CD.
The machine is IBM ThinkPAD T42(Pentium M 1.8GHz, 24x CD-Drive, 2GB Memory).

The results were following.

Original KNOPPIX 5.0.1 CD 2m40s
Accelerated KNOPPIX 5.0.1 CD 1m40s

Accelerated was 1.6 faster than original KNOPPIX.

I took QuickTime video. Have fun.
