The kernel size is almost 5MB (it includes an initramfs).

8 seconds are from the time I call "bootm uImage" and until the init 
script in the initramfs kicks in.

If I can seriously shorten this time I will be glad to know, maybe 
there's something I missed.

Any input will be appreciated.


Thanks,

Boaz.
