Two things you may find useful.
tellnews showusers
will among other things give a rough idea of how many groups each person
read.
Also if you add to dnews.conf
loguse true
then you will get log files u_yyyymmdd.log that record who reads what
in great detail.
Lastly you may find this setting useful
suck_maxgroups 500
I'ts not every specific, but it basically lets you auto uncache all groups if
the total cached number exceeds some preset value. Unfortunately it doesn't
differentiate binaries from non binary groups.
(We'll keep the per client subscribe suggestion in mind for future
developments)
