Making Peppermint run as fast as possible
« on: May 26, 2014, 11:19:18 pm »
Trying to get peppermint running as fast as possible on these older machines.
Dell Optiplex GX270 with 256 RAM or 512 RAM

The students will mostly be using it as a web browser.
Just want to know if there is a way to get it running faster than what it runs stock (just straight up installation).   I mean comparing it to WinXP running on those machines is like night and day already, but Im just wondering.

thanks in advance

Hi Lance

There's an application called preload that caches commonly use programs which helps load them faster you'll find it in the repos or
Code: [Select]
sudo apt-get install preload
You can also try changing  the swap tendency which is generally set too high for normal desktop use, I'm not sure by how much it would speed up the system (if any) but it should make the system more inclined to use ram instead of swap which is obviously much slower, you can alter it by following the instructions below taken from here http://community.linuxmint.com/tutorial/view/998

Good luck

If you can keep your head while all around are losing theirs then you're not quite grasping the situation

I used to change this, but I never seen any change in my computer speed...
I have also read somewhere conflicting arguments about messing with the swapiness, and it should be left exactly where it is at 60 especially if you have less then 1 gig ram on your system...   ;)

I too have never seen any change in performance from changing the swappiness.

I used to change the /etc/init/tty*.conf scripts to not launch as many in order to save RAM. It's not much but every little bit helps. If you can kill extra startup processes anywhere then those will certainly help.

I knew there had to be a way to kill startup apps, thanks for the info Kendall, I will look into this for sure cause I know a lot of stuff is booting i never use... like cups and saned and bluetooth etc....  :)

Just edit the /etc/init/*.conf files to tell them not to launch on any runlevels and you're good. This is for apps that use upstart. You can similarly kill stuff that uses the old init scripts by screwing around in /etc/init.d/ and doing something similar.

I'm not quite so sure how to kill those other processes.
Would some one be able to explain how to kill those processes.
Thanks for everyone's feedback on this

For each service you don't want to launch, edit the /etc/init/*.conf script to comment out the "start on" section. Without it being told when to start, it obviously won't start.

Open file manager pcmanfm
on left you will see PLACES, click the drop down arrow next to places and choose TREE
when the directory tree shows on the left side, click on the arrow next to the  /  in the tree
then go down to etc and click the arrow next to etc, and then find init and click on the word init in the tree and the init folder will open up for you to view....
to edit the files you will need to click the TOOLS up above and choose (open this folder in root)...
enter your password and wait for the folder to reopen as root, now you can right click each file and open them in text editor and edit them.... 
good luck...  :)

If they strictly would like to use Chromium as a web browser with google Drive

do you have some suggestions as to some of the processes that I would be able to not start up.

I disabled the cups.conf, bluetooth.conf
but are there any others that chromium is not dependent on and that it would make a difference in performance.

thank you for your time again
