When given two routes:

Get["/{name}"] _ => "Hello, " + _.name;

Get["/phillip"] _ => "Phillip is awesome!";

Both these routes are identical, but we need to parse the url against both every time.

http://mysite.com/phillip 
^ This route is matched twice.

Literal Segments are scored at 10k, while a Captured Segments are scored at 1k

The route that will be chosen will be `Get["/phillip"]`

http://mysite.com/bob
^ This route is matched only once.

These checks are nothing more than `if (segment == value)` so they are quick even if you have 100s of routes defined.

The only factor that can slow routes down is Regular Expressions, unless you define lots of regular expressions this will be quick.
