Line rate does imply pps at the smallest sized frames in the context of networking equipment performance. Vendors use it extensively in their docs. 64B is the minimum frame size in Ethernet, including interframe gap and preamble its 84B on the wire. It is the same with Ethernet, Gigabit Ethernet and even 100Gbit Ethernet, that source is not correct. https://kb.juniper.net/InfoCenter/index?page=content&id=KB14... |

Network hardware always quote PPS using the smallest sizes. And this makes sense for things like route and switch processors. Perhaps you are confusing that.
You should reread your link a little more carefully. From your link:
">However it is also important to make sure that the device has the capacity or the ability to switch/route as many packets as required to achieve wire rate performance."
The key phrase there is "as required." Almost nobody needs to sustain forwarding Ethernet frames with empty TCP segments or empty UDP datagrams in them. In fact many vendors will spec for an average size. Since packet size x PPS will give you your throughput, if the average packet size is larger you need much less PPS to achieve line rate.
