MongoDB 3.0 Configuration

MongoDB 3.0 is a revolutionary version, thanks to the new storage engine Wiredtiger, which greatly improves performance while improving data compression (300%).

Performance comparison See: https://comerford.cc/2015/02/04/mongodb-3-0-testing-compression/

Installation Documentation: https://docs.mongodb.org/manual/administration/install-on-linux/

If you just installed MongoDB and then started it, I'm sorry, it's still running slowly, the default storage engine is still old MMAPV1

Default configuration etc/mongo.conf, it is really bland, it is actually a yaml format of text, quickly replace it with the following configuration, you can immediately implement the Niaoqianghuanpao.

It is important to note that YAML-formatted files do not support tab tabs, so you should pay special attention to paragraph file alignment, or MongoDB will fail to start.
