Hi - nice to see you again!

try to find out the bottleneck
a) CPU over-load? (vmstat 5)
b) Storage arena fast enough? (find /var/spool/news -print|cpio -ov 
>/dev/null)
What about DNS-queries? Is named, or whatever use use, configured as a 
cache and is it working right?
While fetchnews running slowly, issue a "tcpdump -i /dev/ppp" - are 
there some strange packets in between fetchnew's article-headers? I 
suspect a DNS-query here, which lasts a long time. (Maybe you should 
setup "dnsmasq", a software much easier to setup and to maintain than 
named).
And do a "ping your_up_newsserver" to see, there's always a good 
responsivness.

Regards, and godd luck, Edi
