In and out to the peers may be roughly the same. I really don't have the downloaders that some place like Giganews or Supernews has. Jeremy Nixon and some of the other very Big New Sites have said that users (which none of the local ISPs have boatloads of on broadband) take up multiples of bandwidth compared to feeds, if I'm remembering the discussions correctly. Giganews just signed a deal with Comcast -- there was enough serious complaining by Comcast users about not having Usenet that Comcast is offering the lowest end Giganews package free and Jonah plans to make it very easy for Comcast users to upgrade their systems. Cox Cable went with Supernews. My users probably post more than your average users did at op.net (I believe at one point I was the only person posting more than one or two posts a week). I know I was the only person who noticed when Cynet's main news server (news1.alterdial.uu.net) was UDP'ed. UU.net security people said I was the *only* person who called them. Most people use Usenet to download binaries. I know my users post more than op.net's users did. I could be wrong, but I wouldn't be surprised if they didn't post more to text groups than Netaxs dialup customers (they certainly post more to the groups I read but that's how I found them). > > in fact, ignoring end-user traffic [1], the aggregate across all Usenet sites, > the in + out will be _exactly_ equal. I wouldn't ignore end-user traffic now that those people have T-1 equivalents for downloading and utterly no reason not to, and news reader programs that do things automagically. It's that end-user traffic that I'm referring to. I/O with peers is equal, but if one has a lot of broadband bunnie suckers, then outgoing is going to be quite a lot more than incoming, not that the NSPs don't charge by the megs downloaded now unless they're speedcapping. The only spikes I get is when someone decided to open control.cancel and get all of them so he can grep for rogue cancels (yeah, I allow this). > > [1] and the tiny trickle being pushed in various multi-cast > experiments/projects Now that stuff is really is insignificant. -- Rebecca Ore http://www.ogoense.net ______________________________________________________________________ Philadelphia Linux Users Group - http://www.phillylinux.org Announcements-http://lists.phillylinux.org/mail/listinfo/plug-announce General Discussion - http://lists.phillylinux.org/mail/listinfo/plug
