About 10 seconds on a fairly speedy Haswell box;

It takes less than 2s on my Thinkpad X201s (8 years old, 2GHz Core i7-620LM)
running Debian stable (with a non-optimized build
using --enable-checking and all).

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.
