[ic] bandwidth requirements/server sizing

[Chris Snow]

Thanks Dan, the hardware sizing information is very useful.

For the bandwidth I was looking for some ball park figures based on a
'typical' catalog (if that's possible).  Alternatively, what is the best way
of measuring or calculating the bandwidth utilization for my catalog?
(Assume I know nothing about bandwidth measuring/calculating).

Thanks again,

Chris

absolutely nothing to do with Interchange, right?)  However, I did recently
finish some benchmarking, and I found:
