Slow Julia startup time after sysimage creation (and an unbelievable observation!)

in the official doc : https://julialang.github.io/PackageCompiler.jl/dev/examples/ohmyrepl/
there is a --trace-compile part …

The first goal is to have Julia emit the functions it compiles when running OhMyREPL. To this end, start Julia with the --trace-compile=ohmyrepl_precompile.jl flag.

but this part is missing from your script …

  • no --trace-compile=precompile.jl
  • and the precompile.jl is empty
