[AT&T Samsung Galaxy Note II] chris.l.naish:
For me, using TWRP 2.6.0.1, running CleanROM ACE 4.9:

How long it takes to get from reboot to samsung boot screen. - about 2 secs, no issue there

How long it takes to get from samsung boot screen to twrp. - about 30 seconds, give or take a few...here's where I notice it

How long it takes to get from samsung boot screen to boot animation (start of ROM booting). - also, about 30 seconds, give or take a few...also, here's where I notice it

I tried to attach the recovery.log file to the post, but the forum wouldn't let me for some reason, so the contents are below. Sorry for this making it a longer post as a result. HTH though. :) :
