Bring Julia code to embedded hardware (ARM)

[asprionj]

But the run time overhead remains uncomfortably high, in the order of 10 seconds for a test script with less than 20 lines, or half of that time if the filesystem data is cached in memory (which we can not assume).

Any suggestions on how to further speed up the startup/load time of Julia

To make sure: You compiled everything that is called in the script into the sysimage? That is, the remaining overhead is pure “Julia startup / initialisation”…? So the question would be whether (and if yes, how) this can be eliminated. An embedded system is usually expected (or even required) to start up quickly, so 10s is quite a lot of time (that would be added to the startup time of the system, incl. linux etc., itself).
