Some New Language Benchmarks

I have a small set of benchmarks (adapted from some I found online) that I use to track changes in how programming languages perform between releases. They aren't meant to be some super scientific set of benchmarks, but really just something I can use to gauge how a language is changing over time, and to help make decisions on what to use.

Benchmarks Source Code

The repo is pretty messy, and some of the wiki information is out of date, but

the benchmark code itself is up to date.

Anyway, it's been a while since I've run these - a few SBCL versions have come, and a number of kernel releases - so I've run a new batch of benchmarks. These are just for my desktop this time, a Core i9-10850K with 64GB of RAM. As usual, I run each benchmark three times, and there's four benchmarks (BinaryTrees, Mandelbrot, nBody, SpectralNorm). Then at the end, I take the geometric mean of their runtimes per-language. This is where the "from 12 benchmark runs" comment comes from. A few languages are still missing benchmark implementations, but they're ones I rarely test, and this is why they don't have 12 runs. Finally, there's a 30 second cooldown between each benchmark and each batch to give the CPU time to cool.

So, overall results (ignore "0.000 Joules", I didn't measure energy usage this time around):

Geometric Means:
  C      : 1.502583 seconds,   0.000 Joules (from 12 benchmark runs)
  Crystal: 1.678064 seconds,   0.000 Joules (from 12 benchmark runs)
  Sbcl   : 1.496556 seconds,   0.000 Joules (from 12 benchmark runs)
  Ccl    : 9.756819 seconds,   0.000 Joules (from 12 benchmark runs)
  Clisp  : 201.840503 seconds,   0.000 Joules (from 12 benchmark runs)
  Chez   : 8.111610 seconds,   0.000 Joules (from 9 benchmark runs)
  Pascal : 4.000167 seconds,   0.000 Joules (from 12 benchmark runs)
  Csharp : 3.915367 seconds,   0.000 Joules (from 12 benchmark runs)
  Vala   : 2.919772 seconds,   0.000 Joules (from 12 benchmark runs)
  Go     : 2.017984 seconds,   0.000 Joules (from 12 benchmark runs)
  Luajit : 4.913561 seconds,   0.000 Joules (from 6 benchmark runs)
  Lua    : 59.165653 seconds,   0.000 Joules (from 6 benchmark runs)
Overall geometric mean time based on all recorded runs: 5.259032 seconds
Total time of all results: 6255.290004 seconds

And now a sample run (ignore the RAM usage on Pascal, I think that's wrong):
