We also have groups with very long expiration times on them.  One problem
you will run into is the bitmap in readnews.  I am currently using a
BITMAPSIZE of 8192.

You can eliminate much of the expire overhead by applying the mods that
store the expiration date in the history file.  I think these mods came
from Henry Spencer originally.  I haven't modified inews to keep the
expiration date in the history file, but I have modified expire to not
even read the article unless the recieved date (which is stored in the
history file) plus the default expiration time for that group is older
than the current date.  This technique leaves some articles around for
longer than they otherwise would stay around, but what the hey, we have
100 Gbytes free.
