One thing to check is the size of the resulting bytecode file. When I compiled it, I got a 911 KB .zo file. So the most likely reason is that your macros are just producing a lot of code.
You can run the macro profiler (eg, `raco macro-profiler aw-schema.rkt`) to get a summary of what macros contribute most to the compiled code size. See https://docs.racket-lang.org/macro-debugger/index.html#(part._.Macro_.Profiler) for more details. I also gave a talk about the macro profiler called "The Cost of Sugar" a few years ago at RacketCon. The slides are at http://www.ccs.neu.edu/home/ryanc/talks/racket18-sugar.pdf, and there should be a recording online somewhere. The usual fix is to use helper functions. There are some examples in the slides.
