The only timings significantly changed by the patch are the induct avatars,
with the strange result that the variants which missed the vectorization are
now vectorized, while those previously vectorized are not any more (also true
for the variants of the first attachment). So there is probably some need of a
little bit of tuning.
I have also to regtest and do some further investigations.
