Inline::C is a good place to start. You won't be able to convert the code wholesale, but you can rewrite some sections of your code using C, if you need to.

Now, have you actually identified the sections of your code that are causing any slowdowns? Over 90% of all time taken in the average application is spent in less than 10% of the code. You might want to look at various profiles, like Devel::DProf and Devel::SmallProf.

Another important item is you say I need my code to go as fast as possible. What does this mean? The human brain can only notice things that take longer than a hundredth of a second (or so). What does it gain you if you speed your code up by 50%, but only shave a thousandth of a second off the runtime?

When I code web applications, I try and keep each page under 5 seconds from request to render. That's the time that most people feel a webpage should render in. Client/server applications generally need to respond in under 1-2 seconds. Cellphone applications that go to the network can take up to 30 seconds and still be reasonable. In other words - how fast does fast really need to be?

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
