Clustering allowing one physical server to take over tasks and responsibilities of another physical server that is failed.
Does clustering also increasing the data access performances?
If yes then how?

Clustering is solely a high-availability solution, it has no impact on performance at all.

As Gail said, Clustered Servers is a High Availability solution. If you want multiple servers to increase performance, you probably want "Federated Servers". Please Google the following phrase for multiple Microsoft and other decent links to the subject.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
