Are you doing a > bootstrap build, or a "clean" build? When I reproduced the small part of the performance regression on Fedora x86-64 (the part that's been fixed since then, on emacs-25), I did this: ./autogen.sh ./configure CFLAGS='-g3 -O0' make -j5 time make bootstrap So there's no 'make check', just a 'make bootstrap'. 'make check' is so slow that I normally don't run it these days. We should do what coreutils does, and run the expensive tests only if RUN_EXPENSIVE_TESTS=yes is in the environment. coreutils has three categories of expensiveness, but Emacs could probably get by with two for now.
