Perhaps the VPN provider rate limits to 4M?

I have a paranoid customer who does everything through a VPN service. His download traffic graphs have been pegged at exactly 4M as if I had a 4M queue on him but actually it’s set to 13M for a 12M speed tier. Today his traffic doubled to 8M and I see the number of TCP flows has doubled, 2 different IPs, both in the UK. I can think of several factors that could explain the limited throughput, including CPU horsepower if he is doing the encryption in software on his computer or mobile device. But it seems strange that it goes in increments of 4M. Could this just be the inevitable result of using a VPN server in the UK? What is typical VPN throughput to a server 100 ms away? I don’t have a frame of reference, but 4 Mbps seems kind of low.
