Yes, some things are slower. Most of them I'd say are unexpected performance bugs. I'd think most are easy to fix once investigated, but some can be hard to fix (recent example, `File.read` is quite fast on CRuby). Some things are expected to be slower, for instance constantly redefining (monkey-patching) methods or constants is slower on TruffleRuby, but that's typically because the program is broken and so it'd be slow on CRuby as well. |
