Hey Nick, 

Sorry for the late reply, both my CloudSQL and App Engine are in the same 
project, which is located in northeast-asia. I am connecting through PHP 
using mysqli, and I've tried PDO and I am getting the same result. 
Interestingly, when I connect through host:port, I am getting a lot lower 
latency. I have whitelisted 0.0.0.0/0 for IP and using host:port connection 
and I am getting a pretty low latency (I know it's not secure). Which is 
weird, because unix socket should be a lot faster. Here is my code for both 
type of connection:

YAML :

MYSQL_DSN: /cloudsql/projectname:asia-northeast1:instancename 
MYSQL_USER: user
MYSQL_PASSWORD: password
MYSQL_DATABASE: dbname


Using socket:


$servername = getenv('MYSQL_DSN');
$username = getenv('MYSQL_USER');
$password = getenv('MYSQL_PASSWORD');
$dbname = getenv('MYSQL_DATABASE');
$connection = new mysqli(null, $username, $password, $dbname, null, 
$servername);


Using host:port  :

$servername = "ip.address:port";
$username = getenv('MYSQL_USER');
$password = getenv('MYSQL_PASSWORD');
$dbname = getenv('MYSQL_DATABASE');
$connection = new mysqli($servername, $username, $password, $dbname);


Please let me know if you can tell what's wrong! Thank you very much.
