I found the Netherlands site, ftp.knoppix.nl, to give a faster download of the dvd iso;
possibly because mirrors are still using the university site. Still no cd iso, but the EN dvd
LiveUSB looks very nice and passes testdvd.

Online in 30 sec, shut-down in 10 sec with Win7 laptop and legacy boot.
Times a little faster with Win8 laptop and uefi boot. Not using secure boot.
