What applications could potentially have better performance if they were written in a functional style?

I know that concurrent programs are easier to write in an FP language. The lack of synchronization runtime overhead could improve the performance.

Here is an industry secret: optimizations are dirty and confusing. 

Functional programming is often easier to maintain, allowing you to easily write and maintain 90% of your code base, and focus the messy optimization parts on the 10% where the hot loops are.
