Yes. In this discussion and on Reddit, people still talk about binary vs textual as the source of the problem, but I've argued (based on empirical data) that the lexical details are not the reason for the performance problems.
Also, Swift is marketed as a fast language (also based on LLVM), yet in my measurements it's 20x to 50x slower than Rust for JSON processing. I found that surprising. Would you not?
