Hello I have a question about the load on the processor cores by Gateway Ignition. I have noticed that the load on the individual cores is not evenly distributed, what is the reason for this and is it normal that some are heavily loaded and the rest marginally?

This is very common, and not just for Ignition. Asymmetric loading reduces cache line bouncing in highly multi-threaded workloads (like Ignition) and permits better power efficiency states on the lightly loaded cores. It is entirely possible that the JVM isn't doing this, but your OS.
