Using StringUtils methods faster than Java methods?

Question

I want to know if a method from StringUtils from the Apache Commons Lang library is faster than Java String methods.

I know that this is micro-optimization, but it is necessary because the methods will be executed millions of times.

Methods that use regular expression in Java, for example, split()or string comparison with equals().
