I think the "extra" translations that you are seeing are an effect of
flow accounting.  Once a second, OVS accounts flow statistics to
resubmitted flows via flow_push_stats(), which translates the flow.
It shouldn't be particularly expensive, but if it turns out to be we
could cache the fact that a given flow doesn't resubmit and skip it.

Try "ping -f" and you probably won't see any more xlate_actions calls
than that.
