I came across some old Nimrod benchmarks that mimic those on the Language Shootout page. The benchmarks are for version 0.8 of Nimrod. I thought the community might be interested in taking a look (I haven't seen any discussion of the benchmarks)

Nimrod does very well compared to other compilers (eg. Clang and GCC), and seems to have more concise/readable code. In fact, in some cases Nimrod outperformed slightly, which surprised me, since the Nimrod compiler itself calls a C compiler such as Clang or GCC. I notice that in some benchmarks Nimrod seems to be allocating much more heavily than some of the other implementations (even more than Python, sometimes). Is that due to GC overhead, or what? Also, it appears that Nimrod code didn't work in some cases. It would be interesting to see if the latest version, 0.9.2 performs even better or can compile more of the benchmarks successfully.
