We're currently at 20M of news a day in 1200 newsgroups. Three years ago it was 4M/day and 400 newsgroups. I'd like to propose 1G/day and 100 000 newsgroups as a target for normal operation in some future news system. Start designing now. 1G/day is volume of news generated by posters everywhere, not necessarily volume of news exchanged between two sites. 100 000 newsgroups is a rough measure of breadth. Perhaps newsgroups will be replaced by something better. I just want to inject some real numbers in the fuzzy handwaving of "doing this will help us cope with greater news volume". -- Felix Lee flee@cs.psu.edu

Hmm.. part of the design has to be a fat enough wire leading to my home. A quick calculation | 1 - boomer:david --> bc scale=3 1000000000/24 41666666.666 ./60 694444.444 ./60 11574.074 Says the wire will need to handle over 100Kbits-per-second all day long. Hmm.. up til now my TB+ seemed pretty capable of the job. Sigh.. if only I were Rob Pike AT&T would be willing to pay for T1 lines to the house, ohwell. ;-) ISDN doesn't cut it -- it's only 56Kbaud. But then it will require 6 doublings of traffic. In the past each doubling has required 18 months, up until the a.s.pictures nonsense hit us. Reaching 1G/day should then take somewhere between 3 and 10 years, depending on whether the volume curve is really increasing. -- <- David Herron, an MMDF & WIN/MHS guy, <david@twg.com> <- <- <- "MS-DOS?
