Hi and Happy New Year!

I've looked through the patches and the change seems quite small and
justified. But at the second round, some doubt arises on whether this long
patchset indeed introduces enough performance gain? I may be wrong, but it
saves only several bytes and the performance gain would be only in some
specific artificial workload.  Did you do some measurements? Do we have
several percent performance-wise?

Kind regards,
Pavel Borisov
