Regexps are slow.
When using ByLogialTableRouter we're only operating on small amount of names to be replaced by regular expression.
Adding cache can speed up this a lot.

Sample values for different regexps (time in msec, 10M iterations):

(.*)(x|y)[.](.*)

• without cache: 42091
• with: 150

abc[.](x|y)[.](.*)

• without: 10540
• with: 88
