Hi everyone, I recently discovered Nim and I've been pretty excited by what I've seen of the language so far. I've seen that Nim can get excellent performance on some benchmarks, but I wanted to test its speed myself. I've written a simple benchmark program in a few languages. My program calculates the number of pairs of intersecting polygons in a given list. I have deliberately chosen a naive approach and avoided doing any low-level optimizations. I've written the program with nearly identical structure in a few languages, and I was disappointed to see the Nim version dramatically outperformed by the Rust version. On my machine, my Rust implementation generally runs the calculation in about 75 ms, while the Nim version takes about 300ms. The Nim version is actually significantly slower than a version I wrote in Kotlin, which I found rather surprising. Is there anything obvious that I'm doing wrong? I am building the executable using `nim c -d:release geometry`. My machine is running Windows 10 on an Intel i5 processor.
