First thing, I would try -O2 and -Os. They can be much faster than -O3 and -Oz.
Otherwise, 10-12 minutes sounds extreme even for 12MB, so this is likely hitting an unknown bad case. If you can run a system profiler on it that might show something useful. You can also run with BINARYEN_PASS_DEBUG=1 in the env, which will list times of passes - perhaps one particular pass will be slowest.
