Building Emacs with -O0 should never make Emacs so slow as described
by the OP. Disabling optimizations generally makes Emacs about 2.5 to
3 times slower, but that's still a far cry from response time of a
second or two to C-s.
I use unoptimized builds of the development version all the time,
because optimized builds are very hard to debug.
