CURRENT: ipfw: problems with timeouts and worse network performance

With most recent CURRENT (r300295) I face a very strange behaviour on
all systems running CURRENT with IPFW enabled.
I realize massive network problems, especially when services like
claws-mail, pgadmin3, OpenLDAP clients, drill or even svn try to
connect to their servers. In most cases, the connection couln't be
established due to timeouts, but repeating, like performing svn
in /usr/src gives some results, but this is highly erratic.
The problems vanishes when "ipfw disable firewall" is entered. We use
both custom ipfw-rule-scripts as well as those used with rc.conf
(mostly type WORKSTATION).
The problem is prominet with having /usr/src and /usr/ports updated via
subversion. In 99% of the cases svn drops out with timeouts in case
IPFW is active - but everything seems all right when ipfw is disabled.
As far as I could see this problem affects all CURRENT we use and it is
not NIC specific, but sticks with IPFW.
I reported earlier about broken pipes in ssh sessions to remote hosts,
which occur on an erratic basis. i'm investigating this problem now and
it seems that it is also ipfw-related, but I'm not sure. This problem
is present since a couple of weeks now.
Is there anything known about ipfw problems?
