I installed this hack at
www.tourc.com for automotive forums..... I love it...
I'm just in the process of mirroring all the automotive groups...
it takes a while to catch up with the groups the first few runs of newnews.pl, but is super quick after that... I noticed very little bandwidth increase at all!..... barley enough to measure.... in fact the full mirror (I'm about half done, but I've done some huge groups with 45,000 messages per group and more) of all the automotive groups around 150 or 200 groups will be about 500meg of bandwidth.... (half gig) thats not much, and the runs of newnews.pl after the first mirror take almost no bandwidth....
the biggest problem I encountered was that I had so many groups and messages my searchindex table started getting out of hand... It reached about a gig, and I was only a quarter done, so I killed all the records and set the nntp options to not index the groups that are based on newsgroups and only index local groups.... no that that is done, my whole dbase is arround 40 meg as of may 22, but should be around 80 or so when done!...
the only bandwidth increase I can really see after the initial mirror is done, is all the newsgroup visitors coming to my site!
excellent hack or whatever... thanx!
