Re: how fast

That depends on the system and the equation.

e.g. have a look at iLog (formerly known as CPlex), it solves linear systems
with millions of constraints very fast, but then again that software pacakage
tries to guess/find special structures in the matrix (sparsity, bands etc.)

Why do you want to know this?
