--- Comment #8 from Carlos O'Donell <carlos at redhat dot com> ---
I will note that commit f3dcae82d54e5097e18e1d6ef4ff55c2ea4e621e should only
have impacted the first call to a given function e.g. slowdown caused by
save/restore of more registers during the lazy symbol resolution path.
Subsequent calls should have been just as fast. Something else is happening
here, but given the resolution by the user I'm happy to ignore this as a
problem with libx264.
