Slow on the first run

This is a common problem with dynamic programming languages, but if needed, Julia can generate a sysimage via PackageCompiler.jl to improve performance.

But the last time I tried it, something went wrong causing my julia kernel path to point to the portable one, which is not what I expected.

Problem solved using sysimage, current problem is how to run it on another machine
