Yes, it helps a lot to speed up the process. I copied several
NNTP group processing rules from my "matcherrc" file in .claws to give
you some ideas:

===
[#news/Et-Sept/rec.crafts.metalworking]
enabled rulename "Delete older than 17 days & read" age_greater 17 & ~unread delete
enabled rulename "Bozo Groups" header "xref" regexpcase "limbaugh|politics|survivalism|tricks|kooks|comp.cad|nuclear|gossip|rights|marketplace|religion|\\.fan" & ~watch_thread & unread ignore
enabled rulename "Mark Bozo's Read" from regexpcase "too_many_tools|basil karlo|benny fishhole|Lib Loo|burled frau|egalitarian|wholetruth|createstuf|asheksp|zhang|snothead|pogonip" & unread mark_as_read
enabled rulename "Delete ignored & older than 3 days" ignore_thread & age_greater 3 & subject regexp "^Re:" delete
enabled rulename "Color mark Bozo's" from regexpcase "gunnerasch|richg|pittmanpirate|terrell|steveb\\@" & unread color 3

[#news/Et-Sept/rec.gardens]
enabled rulename "Delete older than 21 days" age_greater 21 delete
enabled rulename "Delete ignored and older than 3 days" ignore_thread & age_greater 3 & subject regexp "^Re:" delete
enabled rulename "windows-1256" header "content-type" matchcase "windows-1256" & unread ignore
enabled rulename "Flag bozos" from regexpcase "wildbilly|charlie|brooklyn1|gunner" & unread color 3
===

Watch the word-wrap. Each line should start with "enabled rulename".
You can edit this file directly, but I think it would be best if Claws
wasn't running at the time. You can also enter it using Claws
"Processing..." menu selections. _Be aware_ though that the syntax is
slightly different between editing it directly or using the menu way.
