Golang Database Connection Pool with mongodb

Question

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

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 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.
