Description
While doing different benchmarks of software using Java Driver, we noticed that in some cases there might be some problems with scaling to high-core machines (think of instances like c6i.metal with 128 vCPUs). More specifically, sometimes it was more performant to launch multiple driver processes (each having 1/Nth of cores) instead of a single big process. However in that case that could have been caused by an older stop-the-world GC algorithm (using older OpenJDK).
Further research and benchmarking are needed, therefore creating this issue to remember it.
