Optimize and speed up your Raspberry Pi

RaspFlash

Ever since my first PC 286 to the present days, I have been obsessed with optimization: an operating system, programming code, an application...

We are going to know how to optimize a little our Raspberry Pi.


At the time of MS-DOS I had the cleaner autoexec.bat and config.sys in my neighborhood, and also created a Windows XP distribution of those Lite called Protini that was quite famous in some forums.

That which does not require running, Why have it in memory? I'd rather have RAM or free space used by processes or programs that do not use.

So I will be putting commands and support for those who need to accelerate Raspberry Pi to infinity and beyond. If you want to bring some other command or trick, you can send it to me and we will build this post among us: D

Let's start with some simple processes for those who just walked into the desktop environment among others. The following commands can be copied to a file for later run or enter them manually one by one.


## Stop the ntp service
sudo service ntp stop

## Stop the triggerhappy service
sudo service triggerhappy stop

## Stop the dbus service. Warning: this can cause unpredictable behaviour
 when running a desktop environment on the RPi
sudo service dbus stop

## Stop the console-kit-daemon service. Warning: this can 
cause 

unpredictable behaviour when running a desktop environment on the RPi
sudo killall console-kit-daemon

## Stop the polkitd service. Warning: this can cause unpredictable 
behaviour when running a desktop environment on the RPi
sudo killall polkitd

## Remount /dev/shm to prevent memory allocation errors
sudo mount -o remount,size=128M /dev/shm

## Kill the usespace gnome virtual filesystem daemon. Warning: this can
 cause unpredictable behaviour when running a desktop environment on the RPi
killall gvfsd

## Kill the userspace D-Bus daemon. Warning: this can cause unpredictable
 behaviour when running a desktop environment on the RPi
killall dbus-daemon

## Kill the userspace dbus-launch daemon. Warning: this can cause 
unpredictable behaviour when running a desktop environment on the RPi
killall dbus-launch

## Uncomment if you'd like to disable the network adapter completely
#echo -n "1-1.1:1.0" | sudo tee /sys/bus/usb/drivers/smsc95xx/unbind

## Set the CPU scaling governor to performance
echo -n performance | sudo tee /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

To be continue...
