golang server not responding with frequent db requests?

Question

MySQL

There is a function for working with the database

db := mysql.New("tcp", "", "127.0.0.1:3306", "root", "", "test")
    
        err := db.Connect()
        if err != nil {
            log.Println("Не удалось подключиться к базе данных")
        }
    
        rows, _, err := db.Query(Query,args...)
        if err != nil {
            log.Println("Не удалось выполнить запрос",Query,err)
        }
        
        return rows

If there are a large number of requests - (in fact, they can be 'clicked' with the mouse, say at a speed of 10-15 per second) goes to the handler - 'Failed to connect and execute the request' and the whole application hangs for about a minute.
After that, for unknown reasons, everything works again.
error read tcp 127.0.0.1:20673->127.0.0.1:3306: wsarecv: An established connection was aborted by the software in your host machine.
Please tell me what is wrong and what can be done

Answer 1

You are connecting to the database on every request, that's really bad.
Connect to the database once when the application starts, and when processing a request, use a ready-made connection.

Answer 2

Try

db.SetMaxIdleConns(n int)
db.SetMaxOpenConns(n int)

to manipulate the available DB connection pool
