Penn runs INN on an AXP 2100 under Digital Unix, so I'm all for 64 bits!

As for 1 article per second - we passed that mark almost 2 years ago.
We cleared 1.1 article per second back in April of 95.

This is a "slow week" - From Flowstats (24 hour periods):
12/27 126595 1.5 articles per-second
12/26 106432 1.2
12/25 81432 .9
12/24 108658 1.2
12/23 136902 1.5
12/21 125610 1.4
According to my last INN weekly report, for the period 12/17-12/23 we
"took" (via nntplink) 1,570,280 articles, roughly 2.5/second
And we don't even take most of the alt.* groups!
(Only 6548 non "upenn.*" entries in newsgroups).
