I do not know what could generate such a difference.
As far as I understand, the problem is related with "peering"-like
functions.
INN 2.5.x has a new parser for NNTP commands but I doubt it would cause
a very huger load for innd.
The Perl and Python filters for innd also check the message-ID of
articles arriving through TAKETHIS. (Before, it was only for IHAVE and
CHECK.)
Do you use wanttrash, logtrash, keyword generation? These functions
have changed.
Did you have a look at River's suggestion?
