[Solved] Reducing startup time and memory usage..?
Hi all,
I am trying to get my ram usage to a minimal when Idle on the computer (No programs open);
I've got it to about 100MB (Did have it at about 60MB but it's risen since?);
Is there anytrhing I can do to reduce it even further?
## Openbox autostart.sh
## ====================
## When you login to your CrunchBang Openbox session, this autostart script
## will be executed to set-up your environment and launch any applications
## you want to run at startup.
##
## More information about this can be found at:
## http://openbox.org/wiki/Help:Autostart
##
## If you do something cool with your autostart script and you think others
## could benefit from your hack, please consider sharing it at:
## http://crunchbanglinux.org/forums/
##
## Have fun! :)
## Start session manager
##lxsession &
## Start Thunar Daemon
thunar --daemon &
## Set desktop wallpaper
nitrogen --restore &
## Launch panel
tint2 &
## Start xscreensaver
##xscreensaver -no-splash &
## Start Conky after a slight delay
(sleep 3s && conky -q) &
## Start volumeicon after a slight delay
(sleep 3s && volumeicon) &
## cb-fortune - have Statler say a little adage
#(sleep 120s && cb-fortune) &That is my autostart script for Openbox.
Can i reduce it even more?
I also use conky:

I'm simply asking if I can reduce my memory usage by adjust or Uninstalling unneeded things.
Thanks,

Re: [Solved] Reducing startup time and memory usage..?
you could stop using Thunar and start using a CLI filemanager like simply bash or midnight commander (which is two-paned) instead.
you could use feh to set your wallpaper instead of nitrogen.
then, there is loads of system-stuff that isn't started through your Openbox autostart, which could do with some cleaning up as well. start up your computer, then do
ps auxin a terminal to get a list of your running apps. if you, for example, do not have a printer connected, and cupsd is running, you could just disable that. same with saned, which runs for scanners. there are a couple more examples but this is all from the top of my head. you could post the output of that command here so we can take a look.

Re: [Solved] Reducing startup time and memory usage..?
from what i see, there is only a bunch of tiny things you can stop. for example, i stopped the firewire-module from loading because i don't have firewire on my laptop. also, you are using volumeicon, which is something i removed because, well, i don't need it. but these are really about shaving off some KBs from your RAM usage, nothing more. so the question is whether that is really useful.
the other thing you could try, as far as startup goes, is to monitor your startup using bootchart. then you can see if things are taking more time than they should. but this is territory where i don't quite know what i am talking about anymore.
you could also check your dmesg and see if there are errors or something in there. try and Google those, try and remove those errors so the bootup is speedier.
all this will not have a huge impact, imo. but it will help a bit.

I've replaced nitrogen with feh already; Got my background to load on boot already.
Easily done.
I guess I can't reduce it much more as they are all low RAM usage.
Thank you for your help; How do i mark this as resolved?
