WARNING: This mod may be degrade SD card life.

What you need:
•MiniTool Partition Wizard for SD
Card Partitioning

•A MicroSD HC 4GB or higher class
6 or class 10

•MicroSD HC Card Adapter
A card reader (if your pc doesn't
have card reader built in | USB
Mount is not adviseable)

•Swapper2 from Google Play Store
[DOWNLOAD]

•ADB Shell or terminal Emulator (to
check if swap is activated)
Make sure you have BusyBox
installed.

Before we start, lets do some
reading . . .

RAM
What is RAM.?

Random Access Memory (RAM) is
temporary data storage that the
CPU uses during calculations. The
more RAM a device has, the more
calculated results the CPU can
store - which means less time the
CPU has to do the same thing over
and over again. In other words, the
CPU can check RAM to see if it
has already made a particular
calculation in the recent past. If it
has, it can use the pre-computed
results instead of wasting
processing time recomputing the
same calculation. In short, more
RAM means a more efficient (and
faster) device.

SWAP
What is SWAP.?

Swap is, in short, virtual RAM.
With swap, a small portion of the
hard drive is set aside and used
like RAM. The computer will
attempt to keep as much
information as possible in RAM
until the RAM is full. At that point,
the computer will begin moving
inactive blocks of memory (called
pages) to the hard disk, freeing up
RAM for active processes. If one of
the pages on the hard disk needs
to be accessed again, it will be
moved back into RAM, and a
different inactive page in RAM will
be moved onto the hard disk
('swapped'). The trade off is disks
and SD cards are considerably
slower than physical RAM, so
when something needs to be
swapped, there is a noticeable
performance hit.
Unlike traditional swap, Android's
Memory Manager kills inactive
processes to free up memory.
Android signals to the process,
then the process will usually write
out a small bit of specific
information about its state (for
example, Google Maps may write
out the map view coordinates;
Browser might write the URL of the
page being viewed) and then the
process exits. When you next
access that application, it is
restarted: the application is loaded
from storage, and retrieves the
state information that it saved
when it last closed. In some
applications, this makes it seem as
if the application never closed at
all. This is not much different from
traditional swap, except that
Android apps are specially
programed to write out very
specific information, making
Android's Memory Manager more
efficient that swap.

Step by Step Guide
How to create Swap Partition

Using MiniTool Partition Wizard

• Plug in you MicroSD HC Card to
your computer using the card
adapter. (Do not use USB Mount)
•Open MiniTool Partition Wizard
and look for the card
•Right Click on it and select Delete
Partition
•Click on Apply to Delete the
Partition
•Right Click on it again and select
Create Partition.

Set the partitions as follows:

1st partition:
Label: Android-SD
Create as: Primary
File System: Fat32
Partition size: as much as you
want!

2nd partition:
Label: Android-EXT3 (2nd
partition is for EXT which you can
use for A2SD or Link2SD)
Create as: Primary
File System: EXT3 (be it a custom
kernel or ROM with EXT4 support,
use EXT3 still -play safe! )
Partition size: MIN: 256 MB MAX:
1024MB (1GB)

3rd partition:
Label: (do not put anything)
Create as: Primary
File System: Linux Swap
Partition size: MIN: 32MB MAX:
1024MB(1GB) RECOMMENDED:
256MB.

After creating partitions, click
Apply to apply changes

Using ClockWorkMod
Reboot to Recovery
•Go to Advanced and Debugging
•Select partition SD card and select
the partition size that delights you.

Swapper preferences: (for kernels
that doesn't have swap partition
support)

•Run swapper at startup (put a
check).
•Swap place: /sd card/swapfile.swp
(you can place it in a folder if you
don't like a messy sd card
structure )….
•Swap size: MIN: 10 MB MAX:
256MB RECOMMENDED: 32MB
(choose any)

•Swapiness: RECOMMENDED: 10MB

•SYSTEM DEFAULT: 60MB MAX:
100MB (choose any)

•Safe unmount (put a check)
•Safe remount (put a check)
•Advanced preferences: (for Kernels
that supports swap partition only)
Use swap partition (put a check)
•Swap partition: /dev/block/
mmcblk1p2

•After setting preferences, press
back and tap on "ON" to turn on
swap. Reboot afterwards

How can I tell if swap is running?
Go to the terminal emulator - or
open adb shell - and run 'free'.
If it looks like this (with zeros in
the swap line), you do not have
swap:

If it looks like this (with anything
other than zeros in the swap line),
you do have swap:

NOTE:
You need to turn off swap before
you mount SD via USB , if you don't
you will not be able to mount sd
as swapfile is active and set to
read only which will deny request
to mount USB Storage.
