Is such a performance impact expected? If so, is there a plan to regain the old speed?
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?
