[Pan-users] suggestions for large groups

[joe . matarazzo]

I was wondering if anyone could give some tips for using Pan with large
binary groups. I have a gig of memory in my machine, and Pan's cache is
set to a gig as well. However, loading a newsgroup with about 2 million
headers ends up causing Pan to start thrashing swap space about 2/3 of the
way through loading the group, or downloading that many new headers. The 
machine slows down to a crawl and the rest of the (down)load takes 
excessively long.

Do people have suggestions on anything else I could do to prevent the 
thrashing for a large group? Is there some setting I could tweak, or 
system parameter? Adding more physical memory isn't an option (I'm maxed 
out). What exactly does Pan's cache deal with? Is there a limit on 
number of headers that would help?

TIA,
Joe
