services.AddMongoDBEntities is very slow with atlas about mongodb.entities

[dj-nitehawk]

the atlas free tier is extremely slow. it's not suitable for any kind of production use. and yes, the first connection is opened on adding the service. see here in the source.

but the max delay i've seen is around 3 seconds for atlas. can you try with a local db and make sure it's the network that's the culprit?

or you can verify by simply try connecting using the official driver and getting a list of collection names. see how long that takes.

my assumption is it's gonna be the same network lag because this library also uses the official driver underneath.

oh forgot to mention, you don't need to register with the services collection on startup. you can simply do the following:

new DB(MongoClientSettings.FromConnectionString(
        "mongodb+srv://user:[email protected]/DatabaseName"), 
        "DatabaseName");

you can place it anywhere in your app and as many times as you want.
