Contents

BootLoader

See How_to_get_rid_of_Google_Analytics for some tuning of /etc/hosts

Less Swapping

Less usage of swap partition (if min 2GB of RAM) 

sudo nano /etc/sysctl.conf
vm.swappiness=5

Programms

Firefox disable Pango rendering lib 

sudo nano /etc/environment
MOZ_DISABLE_PANGO="1"

OpenOffice
If you don't need that extras that java JRE provides then simply disable it openoffice.


SolidStateDisk (SSD)

Better read/write speed via grub's noop parameter 

sudo nano /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash elevator=noop"
GRUB_TIMEOUT = "3"
sudo update-grub

Put temporary files in RAM to minimize writes to the SSD : 

sudo nano /etc/fstab
tmpfs /tmp tmpfs noexec,defaults,noatime 0 0
tmpfs /var/tmp tmpfs noexec,defaults,noatime 0 0
tmpfs /var/log tmpfs defaults 0 0
tmpfs /var/log/apt tmpfs defaults 0 0

Browsers cache to ram (decided not to do)
put cache to /tmp after mounting /tmp as ramdisk (tmpfs)
I decided to put in on my mechanical 2nd hard disk

Disable Auto-FileSystem Check every X mounts

sudo tune2fs /dev/sda1-c -1

Empty Ram

free
sudo sync && sudo echo 3 > /proc/sys/vm/drop_caches
free
