Which web framework are you using? It sounds like your writing separate code to handle each HTTP request.
I wouldn't expect the extra overhead to be a consideration because it would be a one of cost that you would then keep reusing.

It's a technique that I personally, use when I feel it is warranted,
rather than as a matter of course. For example, when it comes to forms
that will naturally reject multiple submissions (for example, a signup
form, where a repeat submission will result in an 'account already
exists' error), I tend not to use the pattern, mostly since it avoids
slightly more complicated handling code on the server, and having to
float error messages around in sessions.
