Base: Speeding up ad-list

[sidki3003]

Regarding speed -- I don't know if this is of any relevance to the Base Config approach, or even applicable, but i thought i'd share:

When switching to Paul Rupe's 3-list approach (AdHosts, AdDomains, AdPaths), i got a significant speed boost, mainly because the list invoking expression could be much better tailored to the actual list content.

There is a fourth list, "AdList", which acts as a hub for the other lists. I was messing around a lot with it to get it right. Now an (off-domain host testing) entry looks like:

Code:

http(s|):\\+/\\+/
  (^([^/]++.|)$TST(uDom)(^.))$TST(flag=(^*.adurl_l:[12].)(.)\9*|*)
  (($LST(AdHosts))\8(^[a-z0-9])$SET(9=AdH \8)
  |([^/]++.|)($LST(AdDomains))\8(^[a-z0-9])$SET(9=AdD \8)
  |[^/?]+*[/._?&;=-]($LST(AdPaths))\8(^[a-z0-9])$SET(9=AdP \8))

Same test with "ftp(s|):\\+/\\+/" and "//". I've never seen an FTP - let alone secure FTP - ad server. That test is just still in to keep that list hashable (and - to a lesser extend - for completeness).

Most of above code isn't exactly interesting, but the tailored list invocation expressions work pretty well for me:
AdHosts: No wildcarding needed.
AdDomains: ([^/]++.|)
AdPaths: [^/?]+*[/._?&;=-]
