I have the impression that Julia commands are often execute very fast (as advertised), but when they are not, it takes ages (up to the point where I’d have to kill it–and system monitor shows that a processor is at 100% indeed) with little in between?
I was solving a matrix equation just now in the QuantumOptics-toolbox, and changing one parameter a bit changed the situation from the one extreme to the other. But I seem to remember similar findings before (outside this toolbox).
In matlab on the other hand for example, it seems to me that execution time is in general more consistent and predictable?
