In order for software to be able to use the full potential of today's networking hardware, TCP needs to be replaced with a protocol that is different in almost every way, he said.

Once there, you can select the date ranges you want and generate a transaction report in PDF or CSV and then you have to wait a bit while it generates the report for you to download. What kind of UI craziness is this? A user's transaction history is such a basic feature, I can't imagine c...
