I have tested the unlock time for Atrix. I performed each type of unlock 10 times and averaged the results.
From pressing the power button to bringing up the home screen:
No security (slider)---------- 2.1s
Pattern --------------------- 3.6s
4-digit PIN ------------------ 4.2s (used 1-2-3-4)
8-char password ------------ 6.5s (used "password")
Fingerprint ------------------ 2.1s
Note that I ignored the 1 miss-typed PIN and 1 miss-types password. If I had counted them, the times would have been much higher.
