Guile 1.9's interpreter is slower than 1.8's interpreter, but 1.9 has a
compiler, and compiled Scheme runs much faster than 1.8.

You're probably not hitting the compiler for some reason. I think that
scm_primitive_load doesn't support autocompilation, where it probably
should. Is that the function you're using to load your Scheme code?

To work around it for now, call `load' from scheme. I know it's ugly but
at least you get the speed that way. Use scm_primitive_eval (scm_list_2
(scm_from_locale_string ("load"), path)).
