I have a generic ADSL router that supports dual bridge and pppoe mode. I have an ADSL account configured on the ADSL router, and have the same ADSL account configured as a pppoe connection on a cisco via 1 of the ethernet ports - so I can change the default route of hosts on the network to compare connections.
When using the connection via the generic router, I have stable transfers. However, internet usage on the Cisco is inconsistent and jitterish. For example, if I try upload a 2mb file via HTTP to a service (e.g. AWS S3), it seems to upload in bursts, and will sometimes fail. Is there anything obvious in my config below that may be slowing down the connection?

This is not my full config - I have tunnel interfaces with crypto configs, lots more routes and a handful more access lists, but just wondering if there's anything in that config that might be causing the inconsistency.
