Cisco EzVPN Question

I have an EzVPN server (ASR router) and client (889 router) set up with full tunnel. The tunnel establishes without any issues and I can ping the inside of the network at the server side and ping the internet through the tunnel, it resolves hostnames and NAT works fine. The issue is the internet is extremely slow and can’t open any websites, so it’s basically unusable. When looking at the virtual interface on the server side I see that the txload goes up to 255/255, so the interface gets overloaded for some reason. Any ideas?

I don't think it explains the txload, but could this be an MTU issue? Try adding the following line of config to the inside interface of both ends of the tunnel:

ip mtu 1370
ip tcp adjust-mss 1330
