Okay, but here it isn't about joining the CL standard, it is
the situation that we have "the Lisp editor" yet our Lisp is
much slower than other people's Lisp, and for no good reason
what I can understand as Emacs is C, and SBCL is C. What's the
difference, why is one so much faster than the other?

Just wanted to mention that SBCL is not implemented in C. It only has a small C runtime containing various GC alternatives and hardware/OS dependent stuff. The rest is Lisp, including bignums and compiler.
