Speed up a Boot time

Whenever Mint boots it runs several scripts that start necessary
background services. By default these are set to run one-by-one but if
you have a processor with more than one core, such as Intel’s CoreDuo
series or AMD’s Athlon X2, you can configure Mint to run the scripts
in parallel. This way all the cores are utilized and quite a bit of time can
be saved at each boot.
To make the change, type the following to open the necessary configuration file in Gedit:

$ gksu gedit /etc/init.d/rc

Look for the line that reads CONCURRENCY=none and change it so it
reads CONCURRENCY=shell . In all position. Then save the file and reboot your computer.
Using this method I managed to shave a massive 20 seconds off my
desktop PC’s usual start-up time of just under a minute.

Cool, I wonder since I would guess you are using a pre-mint 18 install (gedit) if that still works with systemd? I'll have to give this a try when I get home.

Thanks for the tip!

I tried it with Mint 18 - no difference in boot time but it didn't break anything.

I noticed little difference. Period of time at the beginning is a little shorter.

Same here with LM 18.1 and kernel 4.8.

That looks interesting. I may try e4rat on my netbook after giving your earlier suggestion a try (it's dual core). I think e4rat may be especially useful if you compile a live DVD of your installed system, assuming it preserves the file structure.
