Its hard to know what you are trying to do.

Why would you compile with one state, and use dump, is it supposed to
be an optimization?

Creating a new state for each execution is likely to be much slower
than compiling....

You're probably better loading once, storing the function, and then
calling it, in the same state, repeatedly.

And the best optimization you can make is probably using luajit, which
doesn't support lua_dump(), as far as I know.
