This is a pretty simple example, but it should serve as a reminder to use anchors whenever possible considering the impact it has on performance. Here are two regexes to find an IPv4 address. \d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3} ^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{...
never gives back any text. Thus, your regex already has to be fairly specific in order to even use atomic groups; therefore, your performance boost will be incremental. Nonetheless, the possessive quantifier can still be surprisingly helpful. Consider these two regexes to match an IPv4 address:...
