I doubt there's any performance difference. The only thing you *might*
need to be concerned about with $_REQUEST is that depending on your GPC
options, someone might be able to override POST variables from a form by
supplying GET parameters in the URL querystring (or vice versa, as the
case may be). But as long as you're doing good sanity/security checking
on your request input, that shouldn't be a problem.
