We released alpha1 knowing that the install is slow.
I've managed to dramatically improve it with today's commits.
Fixed two recent regressions in Kickstart itself:
Fixed an issue in Features, added patch to Kickstart:
Added two core patches to Kickstart (first one written by me and RTBC-ed by Damien today, the other was already RTBC and written by Damien and Andrei):
- this one provided a 30% decrease in module install time all by itself.
All this decreased the install time for modules (the first part of installation) from 11m50s to 6m15s.
It can be optimized further (of course, with much smaller gains), but I consider it good enough for now.
I also verified that after today's commits, Kickstart installs with a 32mb memory limit.
