Answer 1

Define "optimum" for your application.

The HTTP standard has a limit (it depends on your application):

The HTTP protocol does not place any a priori limit on the length of a URI. Servers MUST be able to handle the URI of any resource they serve, and SHOULD be able to handle URIs of unbounded length if they provide GET-based forms that could generate such URIs. A server SHOULD return 414 (Request-URI Too Long) status if a URI is longer than the server can handle (see section 10.4.15).

  Note: Servers ought to be cautious about depending on URI
  lengths above 255 bytes, because some older client or proxy
  implementations might not properly support these lengths.

So the question is - what is the limit of your program, or what is the maximum resource identifier size your program needs to perform all its functionality?

Your program should have a natural limit.

If it doesn't you might as well stick it as 16k, as you don't have enough information to define the problem.
