# CPU Governor :
echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo performance > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
echo performance > /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor
echo performance > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor
That is a terrible idea mate, it will drain the battery in no time...
The same is true for your GPU "tweak".
echo 2048 > /sys/devices/virtual/bdi/179:0/read_ahead_kb
echo 2048 > /sys/devices/virtual/bdi/179:32/read_ahead_kb
echo 2048 > /sys/devices/virtual/bdi/179:64/read_ahead_kb
echo 2048 > /sys/devices/virtual/bdi/default/read_ahead_kb
This will end up in a lot of trashed data, nearly none of those readings will going to get merged. There is a reason why the red_ahead is not set higher in the main kernel tree...
Do everyone a favor and be a bit careful on what you include
