"Can handle 1 million connections"

Connection rates are almost always highlighted on any networking product that operates at Layer 4 and above. While this type of testing does stress a device's ability to handle incoming connections, it is not a true indicator of how the product will perform in a real-world situation. That's because a TCP connection--or, in testing parlance, a TCP tap--refers only to the connection, not to any traffic that may pass over the connection.

The IT Pro, for example, can handle 1 million connections, but that's all--the connection is opened and immediately closed without any application-layer activity occurring. Opening a connection is one thing; processing the connection's application traffic is quite another.

Connection rates rarely match up with transaction rates, even when transactions consist of minuscule data sizes. The number of connections a product can open should never be used as an indicator of how well it will perform its intended duties. Unless the data sheet indicates that data was actually flowing across the connection--and includes the size of that data--you're better off ignoring this statistic whenever you see it.
