+The `regex` mapping style uses regular expressions to match the full statsd metric name.

+Regular expression matching is significantly slower than glob mapping as all mappings must be tested in order.
+Because of this, **regex mappings are only executed after all glob mappings**.
+In other words, glob mappings take preference over regex matches, irrespective of the order in which they are specified.

-### Choosing between glob or regex match type
-
-Despite from the missing flexibility of using regular expression in mapping and
-formatting labels, `glob` matching is optimized to have better performance than
-`regex` in certain use cases. In short, glob will have best performance if the
-rules amount is not so less and captures (using of `*`) is not to much in a
-single rule. Whether disabling ordering in glob or not won't have a noticable
-effect on performance in general use cases. In edge cases like the below however,
-disabling ordering will be beneficial:
-
-    a.*.*.*.*
-    a.b.*.*.*
-    a.b.c.*.*
-    a.b.c.d.*
-
-The reason is that the list assignment of captures (using of `*`) is the most
-expensive operation in glob. Honoring ordering will result in up to 10 list
-assignments, while without ordering it will need only 4 at most.
-
-For details, see [pkg/mapper/fsm/README.md](pkg/mapper/fsm/README.md).
-Running `go test -bench .` in **pkg/mapper** directory will produce
-a detailed comparison between the two match type.

 ### `drop` action
 
 You may also drop metrics by specifying a "drop" action on a match. For
