My first impression is that it probably has to do with the relatively
large data size of the tbl_nexthop table for l2tpv4, possibly made
worse by the presence of field annotations. The time appears to be
spent mostly in the _Annotation.__eq__, _verify_size_and_set and
_convert_to_bytearray functions. It could well be that this is an
inefficiency in client.py, i.e. it would need to be addressed by
Intel, eventually.

Just a shot from the hip, could be completely wrong :)
