In the general case, non-nested repeat expressions require time proportional to N2, however if the clauses are mutually exclusive then they can be matched in linear time – this is the case with “a*b”, for each character the matcher will either match an “a” or a “b” or fail, where as with “a*a” the matcher can't tell which branch to take (the first “a” or the second) and so has to try both.
