This delay is due to parsing and JIT'ing a bunch of code in both Gadfly and
dependencies.

There is a work-in-progress caching process you could try. See:
https://github.com/dcjones/Gadfly.jl/issues/251#issuecomment-38626716

and:
http://docs.julialang.org/en/latest/devdocs/sysimg/

The PR to make that simpler and module-specific is here:
https://github.com/JuliaLang/julia/pull/8745
