It takes 180s to import Statistics, PlutoUI, Images and OffsetArrays in Pluto on this Macbook Pro with 32GB that is a couple of years old, while the fans are going crazy. If I'm unlucky a worker process will seg fault. All in all the interactive / REPL part (even with stuff like Revise) is kind of a let down thanks to the slow precompilation / lack of caching? I like it, but I really don't see how it is ever going to replace Matlab, R or Python if these issues aren't addressed.
