Are there ways of getting my code to execute faster?

There are two obvious FAQ entries relating to this: How can I compile my Perl program into byte code or C? and How can I make my Perl program run faster? which may enlighten you.

Perhaps the other obvious action you can take is to avoid Moose. Moose is a great, big, lumbering animal and adds a lot of overhead to any non-persistent system. Consider the lighter weight alternatives, or roll your own or else run the Moosish code as a daemon and have your script just interface with that.
