I had a local patch to disable tracking all the extra registers, and gota nice speed up.
Later, Lassi Tuura contributed a "fast trace" patch for x86_64, which
made x86_64 much faster still:

This is likely why you find x86_64 variant fast enough, but i386 too slow.
Later still, I attempted a mechanical port of "fast trace" to x86:
