I worked once in a system that was sending messages to via message queue to Java based service. We once send 60k messages and a Java based system failed to process these over the whole night. Java have a high ceiling for writing high performance systems but in practice it is easy to make a massive ball of mug that performs extremely poorly. In many cases it is easier to write fast erlang/elxir/node application.
