For the past few days, my NewsGrazer has been running really slow:
taking minutes to sort articles, retrieve an article etc, while this
used to take seconds. I get lots of wait cursor action, but no disk seeking
sounds.

Whats going on? Or more important, how to fix it?

Symptoms:

My nntp newserver and the network are fine;
if I do rn from 
another machine on the net, all responses are snappy, at the same
time NG is struggling. 

Also, my NeXT is running fine;
no other big programs running, and if I start some other app, like a 
terminal, it responds fine, while NG is struggling.

If I look at ps while this is going on, I find that NG 
is generally getting 0% CPU time, and is swapped out and
sleeping (SW state),  even though there is no apparent reason 
for it to be so. Once NG gets a few % CPU time, it generally gets 
the job done, but it may end up waiting a minute to get 1 sec of
CPU time, even though the machine is not busy with anything else.

Any idea whats going on here? Is this another NG bug?
