Question

I’m currently writing a PHP application and i noticed that my page loads kinda slow. I takes about 2 seconds (2.0515811443329 to be exact).

I’ve tracked down what the bottleneck was and it’s the part where i’m creating a PDO connection to my MySQL database.

My ‘connect()’ method doesn’t do any exoctic stuff. It simply looks like this:

public function connect ( $database, $host, $username, $password )
{
    try
    {
        $this->db = new \PDO("mysql:dbname=".$database.";host=".$host, $username, $password);
        if ( !$this->db )
        {
            throw new \Exception('Failed to connect to the database!');
        }

        $this->db->setAttribute(\PDO::ATTR_ERRMODE, \PDO::ERRMODE_EXCEPTION);
    }
    catch ( \Exception $e )
    {
        echo '<strong>Exception: </strong>'.$e->getMessage();
        return false;
    }

    return true;
}

So when i comment out the call to the ‘connect()’ method, then my page loads in: 0.035506010055542

This is a huge difference. I can imagine that creating a connection to a database does take up some time, but it takes more than 1,5 seconds… I’m not sure if this is normal?

If it is normal, that it takes up that amount of time then is there a way to store the database connection? Like putting it in a session? Actually, as far as i know storing it in a session isn’t possible. But it would be the ideal solution. Storing the connection somewhere until the user closes his browser.

In anyway, is there a problem with my PDO / MySQL? And can i simply store the connection resource somehow? So that i don’t have to reconnect to my database everytime for every new page?

PS. I’m doing this all on a localhost (Windows).

Answer 1

You’re probably making a connection with ‘localhost’ as address. Try to change that to ‘127.0.0.1’. That should fix the problem.
