I see. However, people with existing installation will have to suffer
from the slow-down, anyway; people will need to upgrade in order to
see the speed improvement. If they need the speed advantage (which
is exactly how much?), they should consider upgrading to 2.4.

That an extension module runs slower in 2.3 than it does in 2.3 is
not a bug in 2.3 - a lot of things run slower in 2.3, yet we don't
backport all performance changes to 2.3, especially if code has to
be adopted to make use of it.
