Mongodb - Connection Pool size not reflecting
Mongodb has default connection poll size eq 5 .
I have a problem with connection pool size always equal 1 if I connect to mongodb by mongodb client and equal 2 if I connect to mongodb by mongoose
regarding to mongoose if I set poolSize=1 the connection poolSize will be one, if I tried to make it higher than two the poolSize will be two only
I also set maxPoolSize for mongoose and mongodb client, not reflecting !!
I am checking connection pool size from mongodb server by command
"db.serverStatus().connections"
However If I logged form client (connections.length) it's always equal 1 , for mongoose and mongodb client as well
I want to know if there is configuration for mongodb server or the operating system " Debian 9 " to update max pool size
I have tried many ways to set poolSize ( By add it as query param or options object )
Mongodb performance is too bad ->
I was testing express http server by jmeter by sending request from one thread infinite loop the throughput was 12000 +
the response was static hello world text
after adding mongoose and send response ( find all records in table has only 5 records ) the throughput is 600+ only
So I would like to know how to maximize connection pool and hacks to enhance mongoose performance
Ps: I have changed ulimit open files to be 64000
Mongoose connection code :
mongoose.connect(dbUrl , { useNewUrlParser: true ,
autoReconnect:true ,
poolSize: 100,
reconnectInterval: 1000,
reconnectTries: 30
});
var db = mongoose.connection;
db.once('open', function() {
console.log(mongoose.connections.length);
});
Mongodb Client code :
var MongoClient = require('mongodb').MongoClient;
MongoClient.connect(dbUrl, {
useNewUrlParser: true ,
poolSize: 1000
}, function(err, client) {
!err ? console.log('') :console.log(client);
});
