Output the number of cores and speed of a server?

I have access to another college's standalone server and am running several experiments on it. However, I don't know how many cores or the speed of the cores in the machine. Is there a way to get that information through the command line? Right now I'm accessing it through SSH.

  John Gardeniers : That's assuming it's a *nix system.

  Dennis Williamson : ...that uses the `/proc` filesystem.
