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.
