Re: [ufdbGuard] ipv4 ipv4list etc support for categories

The 5000 lines in a URL table are definitely much faster than a regular expression, but with this relatively simple regular expressions you will not see much difference.
Regular expressions can consume quite a bit of CPU and memory resources and therefore the recommendation is to keep the total number of regular expressions below 500.
