A single database and insert it into the ten thousand data needs to be three minutes, built a master from an arbitration after only need a minute, who can explain not only the primary database can write? Why write operation will improve the efficiency? This period did not make any read operation,

I found the rs test is slower than the single, to more than double the time

 import time 
The from pymongo import MongoClient 
Def test (rows, url) : 
With MongoClient (url) as the client: 
Coll=client. The test. The test 
Coll. Drop () 
Starttime=time. Time () 
For I in range (rows) : 
Re=coll. Insert (dict (_id=I, time=time. The time (), data=https://bbs.csdn.net/topics/(time, ctime ()) * 1024 * 10)) 
Print (time. Time () - starttime)

Four or five seconds, I insert ten thousand data is not a simple cycle, there is a complex business judgment... You didn't do is index?
