I've got to tell you, readers make a higher load than just ougoing feeds.
Upgrade without doubt. Otherwise you may experience difficulties
accessing your binary newsgroups.

All right, there's no innfeed, but there are readers. It's all the same.
It's even better to have more slower CPUs, than just faster single
one. For newsfeed servers it's all inside out.

If you still haven't got any advice from Russ, then show us your
daily innreport, please.
