The following modifications may VIOLATE YOUR PHONE'S WARRANTY or COMPLETELY BRICK IT. I DO NOT TAKE ANY GUARANTEES about methods described within this article.

PURPOSE: Speed up the T-Mobile's Pulse phone, without applying a custom ROM on it. Also make some modifications to consume less power - extend on-battery runtime.

TO ACHIEVE IT: We need to root the phone, install busybox to have general linux shell commands, then replace the kernel with a smarter one (default kernel does not have swap support). Then we have to create an in-memory swap with SD card based backing swap function (to let more applications fit in phone's memory, e.g.: desktop does not have to completely reinitialize when exiting larger applications, etc.), addition with a method that lowers the wearing of our SD card (re-create it on another area of the card after every restart). Finally some variable tunings required to lower swappiness (from 60 to 10), set lower idle frequency for the CPU (from 240MHz to 120MHz - saves battery) and speed up CPU's frequency scalig when CPU usage increases (from 80% to 50% - faster responses).
