You're in for a bit of a shock then. It is a linear search :p Curious as to
what you think it should look like instead?
Getting back to the original question though, a map should (_should_) be
faster than building a larger and larger regex, particularly if the map is
doing string comparison as opposed to regex searching for each map member.
Building large alternation-oriented regular expressions can get pretty
expensive rather quickly, though some of that will depend on the regex
engine and compile-time options (e.g, are you using PCRE JIT, etc).
