ช่วยด้วยค่ะ เรื่อง mysql connect timeout ใช้เวลานานไป

<?php
	$mtime = microtime(); 
	$mtime = explode(" ",$mtime); 
	$mtime = $mtime[1] + $mtime[0]; 
	$starttime = $mtime; 
	
	/*set_time_limit(3);
	ini_set("connect_timeout","2");
	ini_set('mysql.connect_timeout',"2");
	ini_set('net_write_timeout',"2");         
	*/
	include 'inc01.php';
	$pass = new dbcon();
	
	$COMPLEX_Ping = mysql_connect($pass->host_complex,$pass->user_complex,$pass->pwd_complex);
	if(mysql_ping($COMPLEX_Ping)){
		$BDR_Connect = mysql_connect($pass->host_bdr,$pass->user_bdr,$pass->pwd_bdr) or die ("Could not connect to MySQL at $pass->host_bdr ");
		mysql_query("SET NAMES UTF8");
