I am using a Telebit 19200 modem, SCO-Unix 3.2.2, and downloading
news from Uunet. I have noted that routine downloads using cron
will average 800-1000 cps. BUT if I run the same polling script
from the root prompt, I will get speeds of 1200-1800 cps. Can
anyone shed any light on this?

Smaller bundles always show increased throughput - and you need to bench large bundles to get a "real" idea of throughput. Here on nstar.rn.com, we batch with outbound bundles at 1 megabyte - which saves the long distance caller the additional overhead of sending smaller bundles - which can add up real fast. -- Larry Snyder, Northern Star Communications, Notre Dame, IN USA {larry@nstar.rn.com, uunet!nstar!larry, larry%nstar@mailrus.cc.umich.edu} backbone usenet newsfeeds available Public Access Unix Site (219) 289-0282 (5 high speed lines)
