Sysimage plot in Juno is still slow?


I followed this guide to make a sysimage

I succeeded in doing so, but the result I see is:

julia> @time using Plots
  0.000901 seconds (445 allocations: 27.250 KiB)

julia> @time (p = plot(rand(5), rand(5)); display(p))
Plot{Plots.GRBackend() n=1}
  5.463900 seconds (14.46 M allocations: 735.964 MiB, 6.06% gc time)

So the plotting command is still quite slow for the first run.

This is my precompile_plots file:


Other than this how would I go about testing this from the terminal? I am on Windows and not sure on how to pass start up arguments.

Kind regards
