10KLOC in J is a huge program. I have one such, a stock-trading application, that's over 20K lines; and a program for managing Quiz Bowl tournaments (including a fileserver) that's close to 10K lines; neither in a repo. We can talk about it privately if you like.

Hi all,

I'm a J newbie, and I'm curious about its performance. 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!
