Greetings,
prompted by another posting on the topic, I also noticed a significant
degradation in boot time on google/panther (Asus Chromebox / Haswell
mobile) . I haven't had a chance to bisect commits yet, but did test a
few older firmware builds to confirm my suspicion. Below are cbmem
timestamps from current ToT (2016-04-17) as well as one of my older
builds (2015-10-15). I don't recall any config changes between the two,
but will extract the configs to compare shortly - I just wanted to get
this email out before it slipped my mind (again)
cheers,
Matt
