> Seems to me that the real problem is the 1500 byte MTU that hasn't increased in practice in over 40 years.
As per a sibling comment, 1500 is just for Ethernet (the default, jumbo frames being able to go to (at least) 9000). But the Internet is more than just Ethernet.
If you're on DSL, then RFC 2516 states that PPPoE's MTU is 1492 (and you probably want an MSS of 1452). The PPP, L2TP, and ATM AAL5 standards all have 16-bit length fields allowing for packets up 64k in length. GPON ONT MTU is 2000. The default MTU for LTE is 1428. If you're on an HPC cluster, there's a good chance you're using Infiniband, which goes to 4096.
What are size do you suggest everyone on the planet go to? Who exactly is going to get everyone to switch to the new value?
