Starting from the previous two papers and thanks to Jens Axboe advices I decided to start several test trying to tune the cfq scheduler.

This paper start from what were left behind in the previous one.
It's purpose is to further tests the capabilities and performance of oracle against different linux I/O scheduler.
The workload of choice is transactional. Horahammer is going to simulate a TPC-C workload while the scheduler will be switched dinamically.
