A little late than planned let me say I am very happy with the boot up speed of Porteus.
I know about bootchart etc, but for my SATA drive with not a lot of modules loading I still get to desktop
from bootloader menu in less than 15 seconds. Much faster than my other distro which is Xubuntu.
2) I am still new to Porteus but have just found the tcz2xzm and xzm2dir scripts to be very useful.
I am not a great coder so not suggesting any improvements just stating the facts Sir or Madam
