I don’t know about Elixir specifically, but python is slllllooooowwww. If the operation is CPU bound, you can easily get a 100X performance improvement by rewriting carefully optimized Python in naive Go, Java, Rust, C#, etc. And if you make an optimization pass on that you can usually eke out another 10X. Even on I/O bound operations, in Python you have to choose between the error-prone async framework if you want to improve resource utilization or you stick to the synchronous world and accept extremely low resource saturation. Either way, I can entirely believe that another language would beat Python on both counts. I’ve seen similar results rewriting a Python system in Go with extremely minimal rearchitecting. The silliest thing is that the title credits the improvement to moving toward Elixir rather than moving away from Python (or maybe their case really is ideal for the BEAM VM and wouldn’t translate easily to, say, Go’s runtime model although I doubt it).
