One big factor in performance is whether a process can be parallelized. It can be an interesting computational problem, and these techniques has really gained relevance lately now the the barrier to clusters has dropped (cost and technical complexity). A lot of algorithms (say for solving a massive optimization problem) that were 10x slower in total operations but can be split up and solved in arbitrarily small pieces are suddenly immensely valuable. And in this context, the actual speed of the programming language probably isn’t terribly important.
