I'd like to know the limits of INN.  This message is to solicit some 
data on people's experience with how much INN can handle, particularly 
high volume, relay-only sites, like Kristofer's.  I'd like to know about 
the following:

What is the input volume?  Both byte and article count would be helpful.
What is the output volume?
What storage methods are being used?
Anything significant about the configuration, like running multiple 
innfeeds?  Disk organization?
What OS? CPU configuration, speed? Memory size? Disk type?
Is there other software running that contributes to machine load?
Keeping an overview?
Was any limitation met, and if so, what was it and how was it dealt with?
Site identification (if you'd like it listed in the summary)

For my part, I'll summarize and post any feedback.

My max input volumes are on the order of 120GB/day, a little over 
3,000,000 articles/day.  That's about 1.4MB/second and about 37 
articles/second.  Max output volumes would be that times 3. Clearly, 
we're no where near the top end.  Any feedback would be greatly appreciated.

TIA!

Anne
