Using https://julialang.github.io/PrecompileTools.jl/stable/ to avoid recompiling everytime is pretty convenient now. And there will be https://jbytecode.github.io/juliac/ to build small binaries. I had some good experiences with https://github.com/sl-solution/InMemoryDatasets.jl and DuckDB.jl when DF.jl wasn' t performing well.
