Repetitive Invocation of a single action

[mrprigun]

Hello, I encountered certain obstacles in my use case while attempting to execute the molecular actions. Briefly, I have a service (gateway for the main app with moleculer-web) that looks like this :

module.exports = {
  name: "test",
  actions: {
    hello: {
      rest: "GET /hello",
      handler(ctx) {
        ctx.meta.$responseType = "text/plain";
        return "Hello Moleculer";
      }
    },

    second_call: {
      rest: "GET /second_call",
      handler(ctx) {
        // some actions
        return ctx.call('external.call', params_action_results_above);
      }
    },
  }
};

external.call is located on another node and invocation happens using NATS transporter. By design actions hello and second_call are gonna be loaded to process unique tasks. Before publishing it to production I made benchmarks for each action and received such results on my laptop:

• The hello action works pretty well, the result was ~600rps
• But the second one second_call was very much degraded, I received just ~40rps

Also, I received similar results after deployment to a prod-like environment. I believe this occurs due to external triggering, which is anticipated, but why so much? I've tried to use different load-balancing strategies and bulkhead but didn't receive any significant improvements. Is there a possibility of configuring Moleculer to enhance this behavior or it's some kind of bug?
