Hi there, I just saw this jffs2 patch [1] on lkml and gave it a try to see which impact it could have on boottime. It speeds up boottime of my barebones illume-image by 2.5 seconds which leads to a total boottime of ~47 seconds.
The patch applies cleanly to the current openmoko kernel so it might be worth to stick it in there. Disclaimer: Besides compiling/booting (incl doing some bootcharts) I have not done any testing whatsoever. Cheers, Adrian [1] - http://lkml.org/lkml/2008/11/2/115
