I know this topic has been covered many times already, but since I couldn't find a easy and straight forward how-to to create a swap partition on my X8, I am going to walk you through few easy steps that will let you create a swap partition in 5 mins or so.
First things first I assume you have already the latest version of miniCM7 and nAa kernel, although this mini howto should apply for any phone and any rom out there, as long as the kernel supports swap partition.
First thing you want to partition your SD card in order to create our swap partition, I recommend you to follow this accurately.
Now that we have successfully created our swap partition, we want to boot up the phone and enable our swap partition in order to be accessible to the kernel.
To detect the swap partition that we have just created open up a ADB terminal and type
it will look something like this
write down the exact number of the swap partition and let's activate it by typing
** where X is the number of the swap partition **
We can now check if our swap partition has been activated by executing the command free
Now we want to make our swap partition to be activated at boot time, without having to activate it manually everytime we reboot the phone.
Assuming you know how to at least write and save a text file in VI, let's go back to our fido ADB shell and type
now lets drop few lines in
** where X is the number of the swap partition **
If you are not really comfortable with VI you can also use Nano or even RootExploer or any other root file manager if you are more comfortable with UI.
save it and once again in ADB shell lets make it executable
As last step you may want to change the swappiness value, note that most of the roms have it set to 60 by default, which is good enough in my opinion, although setting it to higher (max is 100) may help to improve overall performance, while setting it to lower may increase interactivity and overall stability.
Temporary change (until next reboot)
Permanent change
As result
** few notes **
I don't intend to take credit for this how-to as it takes few pieces of commands and hints from any guides out there which covers this topic, and anyways its basic linux knowledge really..
So cheers you all and enjoy
