I have a linear system with matrix which eigenvalues are uniformly distributed on the unit circle like this:
Is it possible to solve this kind of system effectively by iterative method, maybe with some preconditioner?

The matrix is very well-conditioned, hence GMRES(k) should work fine without preconditioner.
