How do I load my Node package before express, mongo module in meteor server?

I write a node module to measure performances of the meteor app. I want to load our node module before express and mongodb. How can I load/import my module before express/mongo modules?

I tried to put inside startup. But it does not work for me.

    if (Meteor.isServer) {
      Meteor.startup(function () {
        var myModule = require('mymodule');
