On the ERL it is the default configuration, but this is always the first thing to check since HW offloading may actually not be in use. There are configuration items that will disable HW offload even if it is configured to be enabled, so verifying the actual running state is the first step.
I note that GRE offload is disabled. Since you do have a tunnel configured you may want to enable that explicitly to see if it makes a difference. This even moreso since you mentioned that you noticed the decrease in performance after simply configuring the tunnel.
