Sorry, yes 0:25e-6:0.6.
Yes, I am doing operation later on A.

julia> @bprofile include("Code_withMatrixMul.jl")
  8.476085 seconds (46.76 M allocations: 4.289 GiB, 9.84% gc time, 32.81% compilation time)

BenchmarkTools.Trial: 1 sample with 1 evaluation.
 Single result which took 5.780 s (6.58% GC) to evaluate,
 with a memory estimate of 4.11 GiB, over 41170470 allocations.
julia> @bprofile include("Code_withMatrixPermute.jl")

  5.102955 seconds (40.90 M allocations: 4.558 GiB, 8.03% gc time)
BenchmarkTools.Trial: 1 sample with 1 evaluation.
 Single result which took 6.177 s (7.08% GC) to evaluate,
 with a memory estimate of 4.76 GiB, over 43090389 allocations.

BTW, I should take the average as the computation time or the one after the sentence “Single result which took”
