On CPUs without branch prediction, yes. Subroutine-threaded code has
two branches per primitive, indirect threaded code only one. You find
a number of CPUs where indirect threading is faster than subroutine
threading on the first version of my threaded-code microbenchmark
<https://www.complang.tuwien.ac.at/forth/threading-v1/>. On more
modern CPUs this is rare, though, because they tend to predict direct
branches and returns better than indirect branches.
