I am remastering KNOPPIX V3.6. My dev O.S. is the V3.6 HD install multiuser with HW autodetect. I have used two different computers: a Dell L400 laptop with 733mhz cpu, 256mb ram and 20gig ide HD in three partitions, and a Dell GX300 desktop with dual 733mhz cpu's, 512mb ram and two fast scsi drives in four partitions where the remaster is on a partition on the faster drive and the CD boot partition is on the other drive.

I don't seem to get any additional benefit from with the GX300 except when I run other tasks during a compress I don't get any mouse pointer delays or programs taking 30 seconds to startup like on the L400. The GX300 never uses both cpu's at the same time but switches between them sharing the load. I get the same behavior on MS w2k3 svr. The additional ram and fast scsi drives didn't help much. This seems to be limited by cpu speed. That, or the racing stripes I painted on the L400 really do make a difference in performance.

L400 w/o the -b option takes about 35 minutes to compress the full KNOPPIX distribution.

GX300 w/o the -b option takes about 35 minutes to compress the full KNOPPIX distribution.

GX300 with the -b option takes about 5 hours to compress the full KNOPPIX distribution.

A compression without the -b option resulted in an iso size of 763000832. With the -b option the size is 742182912 for a savings of only 21mb. Doesn't hardly seem worth it unless you are so close to fitting your remaster on your media of choice and need to get that size just a little bit smaller and you can't take away any more packages.

So, what's in YOUR computer?

The first time I tried remastering 3.4 it took 8-12 hours with the -b option & about 2 hours without the -b & ended up with an iso of 1.1 gig from an uncompressed size of 1.8 Gig. For several reasons I did a reinstall & redid the remastering, the next time the 1.8 gig system compressed to just under 700 Meg in about an hour. I have no idea why.
System is a 1.2G Hp pavilion.
I have also concluded the -b isn't really worth the bother unless you really need it.
