No, such a performance change is not expected.

Can you reproduce the problem with the emacs-25 or master branches, 
without manually adding -no-pie to CFLAGS? The bleeding-edge versions of 
Emacs attack the problem in a slightly different way, which might affect 
performance less.

If you still see a performance problem, can you narrow it down, e.g., by 
configuring it with --enable-profiling and seeing where the extra cycles 
are going?
