Somebody in the thread at some point said:
| after collect informations, we can sum up the most important issues for
| boot time:
Hey bootchart is really good step to understand and measure the real
issues, nice work.
| 1. initializing kernel(9 secs)
What actually does that, JFFS2 mount? I use ext2 on SD card, there is
no 9 second delay there.
| 2. initializing boot splash (exquisite/exquisite-write) (8 secs)
| 3. udev (udev/udevd) (29 secs)
mdev on busybox is possible replacement.
| 4. updating dynamic library cache will waste a lot of time (ldconfig)
I already mentioned this some weeks ago, I took it out on the DM2 boot
here and it makes a big difference. And most of the time, it is doing
nothing at all.
