You should not make overly large regex pattern lists. If you are 
making long lists then you SHOULD investigate using dstdomain or dst 
type ACLs where appropriate. Makes a huge difference in access 
control performance.
A really long url_regex acl really can slow things down, and can get 
quite unpredictable to maintain (a small typo in a regex pattern can 
change the meaning significantly)
A really long dstdomain or dst acl should barely be noticeable in 
terms of performance, and are generally much easier to maintain.
