I meant the actual physical link, not the provisioned rate. Most last mile tech encapsulates Ethernet frames into larger super-frames. Decapsulating the Ethernet frames is pretty much at 1Gb line rate. On my GPON link, with shaping in PFSense turned off, I regularly see 4,000+ 1500byte datagrams at full 1Gb link rate hitting my WAN before my ISP starts shaping to my 150Mb/s average. When I had a cable modem, I would see similar, except instead of a constant 1Gb/s, I would see bursts of multiple packets, then a small pause, but eventually the packets started to get more and more spaced as the provisioned average started to kick in. I assumed this was because my DOCSIS3 8x bonded link could only max out around 300Mb/s, even though my provisioned rate was only 30Mb/s.
