For what it is worth keep in mind that the first patch makes
gst_tag_list_from_xmp_buffer go from five minutes to five seconds elapsed time
and the second one to under half a second, possibly much less. I did not bother
measuring accurately.

But in the context of further optimisations, even getting rid of that 48% in
_gst_xmp_tag_get_mapping_reverse completely might only win further 50ms. And
this is with the pathological case of 50k tags.

It probably would matter much more on slow CPUs though so personally I do like
the idea of getting rid of poor algorithms.
