Much Android development has come in the way of schedulers. Schedulers tell the system how to handle I/O operations. More specifically, they control how devices determine which processes can access your device’s memory, and when. With many schedulers out there from Completely Fair Queuing to Budget Fair Queuing, users can tune their Android devices however they want.
ASUS Transformer Prime users running the stock .28 firmeware now have a new option called Simple I/O Scheduler, which has seen some pretty good results. Applied to the Transformer Prime by XDA Forum Member batoo, the scheduler comes in the form of a module that users can install and enjoy. According to batoo:
I compiled SIO (Simple I/O scheduler) for Prime.
It seems faster than CFQ to me.
It was developed mainly for SSD drives!
