使用mongodb的Golang数据库连接池

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

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.
