Similarly for my circa-2010 desktop with an AMD Phenom II X4 910e (2.6 GHz) running Fedora 27, using --enable-checking with a non-optimized build. Typing 'C-h h' adds about 0.7 seconds to the user+system CPU time in a fresh emacs -Q. If I configure Emacs as usual (optimization, no checking) 'C-h h' adds only about 0.4 seconds. If it's taking 10 seconds in a default build, something is seriously wrong.
