I think this is the main cause of the performance difference, but just to make sure, does raco make <myprogram>; rm <myprogram.zo>; time racket <myprogram> take ~4 seconds, where <myprogram.zo> is in a "compiled" dierctory relative to <myprogram>? If so, then the solution could be to use `require-input-port` on a port that has bytecode for <myprogram>, instead of the program source. > I just tried to check what I get with (dynamic-require <myprogram> #f) > instead > of require-input-port. > In turns out that I get a "hash-ref: no value found for key" error > originating > from <mylang> implementation. > It indicates that something went not as is was supposed to go in the > dependent > modules loading. > There is a certain module (I will call it "functions") that, when loaded, > fills up the hash table in another module ("functions-table"), and this hash > table is being used by the language implementation.

I'm stumped here. I can imagine a problem where the "language implementation" is in the reader, in which case it wouldn't get run when loading from bytecode, but that doesn't explain why `racket <myprogram>` works --- unless the initialization is also triggered by a `main` or `configure-runtime` submodule, which would be run by `racket <myprogram>`. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
