Broadly speaking the daily volume is something like 2.8TB/day for the whole feed, or somewhere in the ballpark of 1GB/day for the non-binaries feed.

You'll have to use many terabytes of disk to get even a modest hit-rate, and the performance benefits will be slight. For text, there's no point in running a caching server rather than a real one, since the incoming bandwidth for text is so small (couple of hundred kbits) and the storage requirements so modest (one 36GB spool disk will hold a month's traffic). -- Andrew, Supernews http://www.supernews.com -- individual and corporate NNTP services
