node.js - Node/Express memory increase on every request -

-

i have simple express 3.2 app returns 200 when posted to. watch memory rss of node (v0.10.5) process , every request increases memory 4kb or so.

the server code quite simple: 

var express = require('express');  var app = module.exports = express();  app.set('port', process.env.port || 3000); app.use(express.favicon()); app.use(express.bodyparser());  require('./apps/events/index')(app);  app.listen(app.get('port'), function(){   console.log("express server starting..."); });

and corresponding controller code :

// ./apps/events/index.js var events = function(app) {    app.post('/events', function(req, res) {     res.writehead(200);     res.end();   });  }     module.exports = events;

is there in code causing this? normal (hopefully not). or measuring wrong thing? put version of script production , node process started @ 16mb memory use, , after load testing (20,000 hits) increased 32mb.

keep profiling server. find memory usage levels off on time. try 200,000 requests , see if things change

also if there memory available operating system try use it. 32mb of ram not enough concerned about.

this talk worth watching. python concepts same node.js
