Right. The 5.3 second timing is if I open a new repl. Precompilation only happens the first time you load a package (assuming the precompilation doesn’t error)
So it takes about 10x longer (53 seconds) to run
@time using DifferentialEquations on my system then…
The 5.3 seconds @Oscar_Smith is reporting is from a much more recent non-released version of julia.
You might want to try downloading a nightly version of julia and see how that fares.
I’m short of ideas… my only thought is that you have some sort of encryption on your SSD that’s significantly slowing down file IO.
