MongoDB在Azure平台上非常慢

Question

I was created MongoDB database in Linux Server ( Standard D2 v2 (2 cores, 7 GB memory) ) on the Windows Azure Platform.

I'm testing data insert to database with following codes. But result is not good..! 47 second for inserting 100.000 record very bad. What is the problem?

Codes for insert to mongodb

string connectionString = "mongodb://root:bitnami@myserveraddress:27017";
var client = new MongoClient(connectionString);
var database = client.GetDatabase("testdb");
var collection = database.GetCollection<Item>("foo");
var documents = Enumerable.Range(1, 100000).Select(i => new Item
{
    Address = "Address " + i,
    City = "City " + i,
    Index = i + 1,
    Name = "Name " + i,
    Status = i % 2 == 0,
    Surname = "Surname " + i,
    Title = "Title " + i,
    Town = "Town " + i
});
var models = documents.Select(s => new InsertOneModel<Item>(s)).ToList();
Stopwatch sw = new Stopwatch();
sw.Start();
var result = collection.BulkWrite(models);
sw.Stop();
Console.WriteLine("Seconds:" + sw.Elapsed.Seconds);
result.InsertedCount.Dump();
collection.Count(p => 1 == 1).Dump();
