I have an application where node.js which listen and populates rabbitmq
with messages, this performs well without https. The load is around 500,000
messages to be processed per hour.
Using https the same application crawls and cpu is around 100% usage.
Here is the server script.
---
var express = require('express');
var app = express();
var fs = require('fs');
var https = require('https');
var http = require('http');
app.use(express.bodyParser());
var utils = require('connect').utils
var amqp = require('amqp');
var connection = amqp.createConnection({url:
"amqp://guest:guest@localhost:5672"},{defaultExchangeName: ''});
connection.on('ready', function() {
console.log('connected');
});
app.get('/', function(req, res){
fs.readFile('/server/index.html', 'utf8', function(err, text){
res.send(text);
});
});
app.get('/robots.txt', function(req, res){
fs.readFile('/server/robots.txt', 'utf8', function(err, text){
res.send(text);
});
});
var options = {
key: fs.readFileSync('../cert.key'),
cert: fs.readFileSync('../cert.crt'),
};
app.post('/process', function(req, res) {
var messageToSend =utils.merge(req.headers,req.body);
var n = messageToSend['id'];
//// decide even and odd queue on last char of id
if(parseInt(n.charAt(n.length -4)) % 2 == 1){
var queueToSendTo = "odd";
}else{
var queueToSendTo = "even";
}
connection.publish(queueToSendTo, messageToSend);
res.send(200);
});
app.setMaxListeners(0);
var httpServer = http.createServer(app);
var httpsServer = https.createServer(options, app);
httpServer.listen(80);
httpsServer.listen(443);
The server is a VM on a dual CPU hardware with 8 GB of RAM.
Only processes running are of rabbitmq and node.js.
I am new to node.js please help in identifying ways to improve performance
of SSL.
Many Thanks
- Sachin.
