I know this is pretty simple, but I never ever did at any point implement a hash table, just went more or less straight to programming in Assembler in a semi-mature system, then to MFC on Windows since about 1998. Performance-wise, my single-threaded test runs about 6 times faster than the equivalent JS, which puts it in the C ballpark. I was really pleased about the performance under multi-threading. With 4+ threads, it's near to being 4 times faster, and the bucket lock only spins occasionally (prints a few '.' but still works).
