There was certainly proximity, if not a direct connection.

This question is difficult to answer. As a _langage_ there's little that
makes SML inherently slow; the MLton compiler does full-program
optimization with advanced optimizations and generates code that's pretty
performant. There are certainly other SML implementations that generate
slow code; MoscowML comes to mind: it generates a byte code that's not
known for speed. SML/NJ is pretty zippy, but I've never tried to write
anything performance-critical with it.
