Poor results using WriteVTK?

New to Julia

Hello!

I have made a very simple code to save point data + one point data array:

using WriteVTK

using Random
using Test

function write_vtp(filename::String, points, attribute)

    polys = empty(MeshCell{WriteVTK.PolyData.Polys,UnitRange{Int64}}[])
    verts = empty(MeshCell{WriteVTK.PolyData.Verts,UnitRange{Int64}}[])

    # Note: the order of verts, lines, polys and strips is not important.
    # One doesn't even need to pass all of them.
    all_cells = (verts, polys)

    fname = filename * "_2D"
    vtk  = vtk_grid(fname, points, all_cells..., compress=true, append=false)

    vtk["my_point_data"] = attribute;

    vtk_save(vtk)
end

function main()
    Np = 1280
    points = rand(2,Np);
    filename = "polydata"
    attribute =  [randn() for i = 1, j = 1:Np];
    @time filenames = write_vtp(filename, points, attribute)
end

main()

Running this code though and just benchmarking using @time:

5.363723 seconds (47.69 M allocations: 1.383 GiB, 4.40% gc time)

Which is quite poor considering N = 1280 - I believe I am doing something wrong, but I cannot figure it out. Would anyone know why?

Kind regards

I did not do anything wrong, there seems to be some issue with my Atom version:

I found the mistake. Whenever I press “f5” it runs in debug mode for some reason - that is why I get that weird result. What is the shortcut for running a file without debugging in Juno?

EDIT: A temp. fix after pressing f5 is to enable this option:

Then it runs as if it is without debugging
