I do wonder in particular about the startup time "time-to-plot" issue. I last used Julia about 2021-ish to develop some signal processing code, and restarting the entire application could have easily taken tens of seconds. Both static precompilation and hot reloading were in early development and did not really work well at the time.

On a 5 year old i5-8600, with Samsung PM871b SSD:

  $ time julia -e "exit"
  real    0m0.156s
  user    0m0.096s
  sys     0m0.100s

  $ time julia -e "using Plots"
  real    0m1.219s
  user    0m0.981s
  sys     0m0.408s

  $ time julia -e "using Plots; display(plot(rand(10)))"
  real    0m1.581s
  user    0m1.160s
  sys     0m0.400s
Not a super fair test since everything was already hot in i/o cache, but still shows how much things have improved.

That was fixed in 1.9. Indeed it makes a huge difference now that you can quickly run for the first time.

on a macMini (i.e. fast RAM), time to display:

- Plots.jl, 1.4 seconds (include package loading)

- CairoMakie.jl, 4 seconds (including package loading)

julia> @time @eval (using Plots; display(plot(rand(3))))

  1.477268 seconds (1.40 M allocations: 89.648 MiB, 2.70% gc time, 7.16% compilation time: 5% of which was recompilation)
