I was wondering, if mongoose uses its own processes/workers internally to handle multiple access to a MongoDB via one connection?
I could not find any information.
You can specify the pool size of the Mongoose connection using:
var uri = 'mongodb://localhost/test';
mongoose.createConnection(uri, { server: { poolSize: 4 }});
Read 'Connection Pools' at http://mongoosejs.com/docs/connections.html
