If I understood correctly, seeds are used to prevent dictionary attacks
with precomputed password hashes.

However, if somebody finds the correct seed, he could again calculate
the hashes on a different, very fast computer, couldn't he?

So how long does it take to calculate - let's say - one billion hashes?

Do I really gain significant security improvement in using seeds?
