This should not take more than 100 milliseconds in this day and age, folks.
This is the info I was looking for. Julia is such an awesome language, but I can't use it due to latency. As soon as this gets fixed I would switch over all of my data analysis in a heartbeat.
Why is latency a concern for you? Are you running a lot of short, one-off scripts? If so, an easy solution is to just keep a julia session running and re-use it for each each script rather than constantly starting up and closing julia sessions. DaemonMode.jl [1] is a package that was recently developed that makes this workflow effortless.
Another option if you've got some production code that needs to be run over and over again is to create a custom sysimage with everything AOT compiler. PackageCompiler.jl [2] makes this workflow pretty easy nowadays.
