I tried to reproduce this on my machine, and ran into some trouble (the code had
warnings that caused compilation to fail). Although your patch is evidently
intended only as a quick benchmark and not as an actual change, I worry that the
benchmark isn't realistic enough, as some usage of EQ in C code will need to
change to Feql or equivalent. Also, the C code will need to change how hashing
works since XHASH etc. must be consistent with eq.
Looking into this a bit more, I discovered that eql currently operates
incorrectly on NaNs, as it's inconsistent with how hash tables work. I installed
the attached patch into master to fix that.
I'll try to look into doing a benchmark like yours with all the above in mind.

Subject: [PATCH] Fix bug with eql etc. on NaNs
Fix a bug where eql, sxhash-eql, memql, and make-hash-table
were not consistent on NaNs. Likewise for equal,
sxhash-equal, member, and make-hash-table. Some of these
functions ignored NaN significands, whereas others treated
them as significant. It's more logical to treat significands
as significant, and this typically makes eql a bit more
efficient on floats, with just one integer comparison instead
of one to three floating-point comparisons.
* doc/lispref/numbers.texi (Float Basics): Document that
NaNs are never numerically equal, but might be eql.
* src/fns.c (WORDS_PER_DOUBLE): Move to top level of this file.
(union double_and_words): Now named, and at the top level of this file.
(same_float): New function.
(Fmemql, Feql, internal_equal, cmpfn_eql): Use it, so that
the corresponding functions treat NaNs consistently.
(sxhash_float): Simplify based on above-mentioned changes.
* test/src/fns-tests.el (fns-tests-equality-nan): New test.

The @acronym{IEEE} floating-point standard supports positive
infinity and negative infinity as floating-point values. It also
provides for a class of values called NaN, or ``not a number'';
numerical functions return such values in cases where there is no
correct answer. For example, @code{(/ 0.0 0.0)} returns a NaN@.
-Although NaN values carry a sign, for practical purposes there is no other
-significant difference between different NaN values in Emacs Lisp.
+A NaN is never numerically equal to any value, not even to itself.
+NaNs carry a sign and a significand, and non-numeric functions like
+@code{eql} and @code{sxhash-eql} treat two NaNs as equal when their
+signs and significands agree. Significands of NaNs are
+machine-dependent and are not directly visible to Emacs Lisp.
Here are read syntaxes for these special floating-point values:
