That number is a little bit of a cheat because I was using llvm-project main which doesn't demangle Swift method names.  I also tried a run with the Xcode 16 lldb (which does demangle swift names, like swiftlang main which you're testing on) and it took around 7.3 seconds.  There could be other differences, but there's a good bit of swift code in all the system libraries, that's probably what the difference was.
