Doesn't Emacs has some code which is enabled when it's compiled without
optimization?  Some additional checks or asserts.  Won't it affect the
performance enough to show a false picture?

How do I switch between native image API and non-native?  Should I compile it
with the flag --with-native-image-api?

Mine is 1.6.46.  Would it help to check Emacs with your version?  I guess I can
compile everything from the source.

A little off-topic.  Who should I send the messages to and who should I add to
"Cc" when I want my message to be seen by both of you?
