Thanks for your feedback.

Two quick notes, before others give you a more complete answer : 

* using 'pylint -e' will only report Errors and therefore considerably
speed up things
* disabling the similarities checker can significantly improve speed,
especially when running on a large code base. I'm responsible for this
part of the code, and the complexity (from the top of my head) is
O(n**2) (n being the number of lines in the code base). We should
probably disable it automatically (unless the user explicitely asks for
it) when the number of lines exceeds some threshold.
