Such regexps can, however, be slow. (Although .+ can be slow as well.) Let's try something a tiny bit more complicated (but still simple). irb(main):001:0> re =3D /.+?a.+?b/ =3D> /.+?a.+?b/ irb(main):002:0> s =3D "ac"*1_000_000 + "b"; nil =3D> nil irb(main):003:0> s =3D~ re =3D> 0 This run fasts. Now, what if it can't match? irb(main):004:0> s =3D "ac"*1_000_000; nil =3D> nil irb(main):005:0> s =3D~ re I have no idea what the output is - it's been running for a few minutes... the same happens if you substitute .+? with .+. This is a bad case of catastrophic backtracking - http://www.regular-expressions.info/catastrophic.html - and stems from the fact that matching a regex to a string is asymptotically exponential. In short - you should never use .+ or .+?, unless you have a very good reason or know precisely what kinds of input you will get.
