So the answer to the question, Why is SBCL faster?
is "optimizations". And the answer to the question, Why don't
we have those optimizations? is "they are not portable"?
But isn't that what we do already with compilation and in
particular native compilation, why can't that add
optimizations for the native system?
Some commands/Elisp on that (compilation and native
compilation) as a side note, maybe someone finds them
entertaining:
