In general, numpy/scipy is quite faster than R: it does not have the pass by value semantics for once. I am also skeptical about writing a "new" R: the main value of R is in the R packages. Any new language would threw that away.

- cdavid 16y agothanks, I will take a look at it at home (where I have enough memory to deal with that kind of matrix). As I said, the scipys.sparse is pretty rough and too low-level, but 3 sec vs 8 hours is way too long to be normal. (I forked your gist so you know how to contact me)
