Performance and Optimization
So is this code fast enough? Using the GHC interpreter, it takes around a second or two to do the lead-gold example (both directions), and a few seconds more for the ruby-code example (also both directions). With the GHC compiler, this reduces to a fraction of a second—even without turning on the optimization options of the compiler. It’s probably fast enough.
GHC provides some good profiling tools to help diagnose and track performance issues. The following snippet is part of the standard time and space profile produced by running the ruby-to-code search 1,000 times (taking around 10 seconds, so 0.01 seconds per search). This is without any compiler optimizations.
The profiler result indicates that seventy-eight ...
