More glaring about the claimed performance gain is that they didn't mention what code they ran (as far as I could see). Was it a selected small piece of code or was it a big Django monolith? As I didn't see any mention of what code it was I'm going to assume the former, and that the latter will actually get worse performance. Because that is what typically happens when someone build a new JIT compiler. It takes a couple of iterations of optimizations for them to become useful on nontrivial code.
