Guys,
are there any guidelines when making product selection in terms of throughput.
i know port density, service requirements and cost etc are pretty obvious
things, but when you it comes to throughput how much leeway should you give in
making your choice.
Ive never been involved in sales or testing side of things, so if someone can
provide examples to help explain that would be good.
