Brian Clozel 567265123b Avoid using regex matching for static patterns Prior to this commit (and the previous one), the `AntPathStringMatcher` (inner class of `AntPathmatcher`) would compile `Pattern` instances and use regex matching even for static patterns such as `"/home"`. This change introduces a shortcut in the string matcher algorithm to skip the `Pattern` creation and uses `String` equality instead. Static patterns are quite common in applications and this change can bring performance improvements, depending on the mix of patterns configured in the web application. In benchmarks (added with this commit), we're seeing +20% throughput and -40% allocation. This of course can vary depending on the number of static patterns configured in the application.

Brian Clozel 567265123b Avoid using regex matching for static patterns

Prior to this commit (and the previous one), the `AntPathStringMatcher`
(inner class of `AntPathmatcher`) would compile `Pattern` instances and
use regex matching even for static patterns such as `"/home"`.

This change introduces a shortcut in the string matcher algorithm to
skip the `Pattern` creation and uses `String` equality instead.
Static patterns are quite common in applications and this change can
bring performance improvements, depending on the mix of patterns
configured in the web application.

In benchmarks (added with this commit), we're seeing +20% throughput
and -40% allocation. This of course can vary depending on the number of
static patterns configured in the application.
