This research applies to 'NUMA' systems. Commonly servers with multiple physical CPUs that each have a connection to their own memory banks. They can access memory of the other CPU by requesting it, but that take time. So the process scheduler has to take that into account. Usually by keeping processes a slight bit affixed to the place where it was started.

Off-topic, but high-performance long running processes are mainly programmed in C, C++ & Java. Maybe stuff like Rust and Swift in the future. Fortran if you are doing mathematical computation, but then you'd probably already use it if you need it.

For what I estimate that you mean with high traffic on PHP or node systems on multiple servers, probably you want to look at Elixir and it's Phoenix web framework. It's more appropriate for responsiveness (as in low latency). And less boilerplate than Java. |> http://www.phoenixframework.org/docs/overview
