Exactly, 10% is quite significant. It can easily happen for perfectly
legitimate reasons, but there's a chance it's an undesirable side-effect
of some change which has a more global impact.

PS: When I tried it here, `git bisect` pointed the finger at:

Allow zero-argument rx `or' and `seq' forms
Make the rx `or' and `seq' forms accept zero arguments to produce a
never-matching regexp and an empty string, respectively.
* lisp/emacs-lisp/rx.el: Require cl-extra.
(rx-constituents, rx-or): Permit zero args.
(rx): Amend doc string for `or' and `seq'.
* test/lisp/emacs-lisp/rx-tests.el (rx-or, rx-seq): Test the change.
* etc/NEWS (Changes in Specialized Modes and Packages): Mention the
change.
which suggests the 10% increase is localized: I guess we "require
cl-extra" right when we happen to be (near) the deepest recursion and
since it's not yet byte-compiled it causes yet more recursive
eager-macroexpansion.
