Golang Database Connection Pool with mongodb
问题
在过去的几天里，我一直在一个性能测试项目上进行一些测试场景，其中我使用了golang + mongodb的组合，结果非常令人印象深刻。然而，当发送多个请求时，性能会急剧下降，我猜测问题可能是因为没有连接池（也许是这个原因？）。我是一个Java开发人员，对于MongoDB，Java驱动程序隐式地提供了一个连接池。
所以，是否有连接池，还是我需要自己创建一个？
谢谢。
英文:
In the past few days I have been making some tests scenarios on a performance test project, where I have a combination of golang + mongodb and the results where really impressive, however, when you send a multiple request, the performance drops dramatically and I guess the problem because there is no connection pooling(maybe?), I am a java developer and the mongodb java driver for mongodb has implicitly a connection pool.
So is there a connection pooling or I have ti create one on my own ?
Thanks

根据MongoDB-GO-Driver官方标准（目前时间为2020-01-29），官方驱动程序本身将维护一个连接池，您只需要设置连接池的大小（最小值和最大值）。

顺便提一句，mgo似乎没有得到积极维护。
英文:
At the current time (2020-01-29), according to MongoDB-GO-Driver official standard which was NOT documented publicly, the official driver itself will maintain a connection pool, you just need to set the pool size (min&max).
The referrence can be found at: Official GitHub Repo
BTW, mgo seems not actively maintained.

Profile，你将会成功。胡乱猜测只会浪费你的时间。

如果你正在使用令人惊叹的mgo驱动程序，那么你已经内置了自动管理的连接池。

Profile and ye shall succeed. Wild guesses will only waste your time.

If you're using the amazing mgo driver, then you have auto-managed connection pooling built-in.
