I believe the reason Scribble is slow on your file has to do with algorithms and logic in Scribble that have poor performance characteristics on large files, and nothing at all to do with the fact that Scribble is implemented in Racket. With a reproducible performance benchmark for running Scribble on large files, I'm sure a dedicated Scribble expert could do a lot to optimize the internals of Scribble and fix the performance problems you're experiencing. That said, I'm no Scribble expert.
