I was going to post the same.

Gentoo + Linux 3.14 + ZFS + dual SSDs + Macbook Pro 17" hardware (~2010).

Theory: Hardware subsystems on MBPs may have relatively strong power up speeds versus some other laptops.

As the slowdown is waiting for the disk to spin up, anything with an SSD will restart faster than something without...

Do you have hibernate working on that setup or just resume? ZoL is great, but not having hibernate is a killer.

Whatever pm-suspend is. Works great for me.

Debian SID: not quite so fast but certainly close. Thinkpad X00s.

    keith@mocha:~$ uname -a
    Linux mocha 3.13-1-amd64 #1 SMP Debian 3.13.7-1 (2014-03-25) x86_64 GNU/Linux

Lucky you. Mine manages to hang before I can fully open my laptop lid! (12.04 LTS). Reverted to windows and using Linux in a VM.

Lenovo T400 here with 12.04 LTS, have a similar problem. Using the instructions from https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_T400#SU... I managed to reduce it from about 1-in-3 to 1-in-10, but it's still not ideal.
