On my new machine it's 0.25 seconds vs. 0.75 seconds. :-) But I suspect it's somewhat slower on less spiffy machines. > When I select the whole group, Gnus says "scoring" within 3 or 4 > seconds of beginning entry, which then takes 28 seconds.

Yes, entering a biiig group takes a long, long time, but that's harder to do something about. :-) But it isn't just the group entry time that might make it worthwhile to do something about the storage -- it's also the mail splitting. (And since the Agent uses nnml for its storage, it also affects article fetching.) Doing a fetch in an Agent that hasn't been expired in a few months is slow -- by and order of two or three times slower than doing it in a freshly expired Agent. -- (domestic pets only, the antidote for overdose, milk.) larsi@gnus.org * Lars Magne Ingebrigtsen
