I did one casual test on http://jsoftware.2058.n7.nabble.com/J-on-Julia-benchmark-td53833.html. For the tests in the link above, the speed is at the same league with python. Note that in the post the last test of matrix multiplication was unfair since all other languages called into LAPACK except J.

I've seen statements that J has "very high performance", but I haven't seen actual benchmarks to back that up. How does J compare to languages like C (which are known to be very fast) or Python (which, being interpreted, are usually much slower)? Also, I haven't seen any large (> 10KLOC) programs in J. Does someone have a link to a J repo hosting a significant project? Thanks! -- Cheers, Gautam C.
