Welcome to the MySQL monitor. Commands end with ; or /g.

使用的表结构：
DROP TABLE IF EXISTS `mytable`;
CREATE TABLE `mytable` (
`id` int(10) NOT NULL AUTO_INCREMENT,
`addtime` int(10) NOT NULL,
`title` varchar(255) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
php操作MySQL的程序：
$type = $_GET[‘type’];
print_r($_GET);
include_once(“gettime.php”);
$btime = getmicrotime();
$loop_cnt= 1000; //循环次数
$db_host = ‘127.0.0.1’; //
$db_user = ‘sunss’; //
$db_pass = ‘123456’; //
$db_name = ‘test’; //
$db_link = mysql_connect($db_host, $db_user, $db_pass) or die(“Connected failed: “.mysql_error().”/n”);
mysql_query(‘set names utf8’);
mysql_db_query($db_name, $db_link);
if (“put” == $type) {//修改
$i = 1;
while ($i <= $loop_cnt) {
$title = “jkjkjkjkjkjkjkjkjkjkjkjkjk”;
$tt = time();
$sql = “update mytable set addtime=”.$tt.”,title='”.$title.”‘ where id='”.$i.”‘”;
$res = mysql_query($sql);
if (FALSE == $res) {
echo “update failed!/n”;
}
$i++;
}
} else if (“delete” == $type) { //删除
$i = 1;
while ($i <= $loop_cnt) {
$sql = “delete from mytable where id='”.$i.”‘”;
echo “delete sql: “.$sql.”
“;
$res = mysql_query($sql);
if (FALSE == $res) {
echo “delete failed!/n”;
}
$i++;
}
} else if (“post” == $type) { //添加
$i = 0;
while ($i <$loop_cnt) {
$title = “hahahahahahahahahahahahahahahahahaha”;
$tt = time();
$sql = “insert into mytable(addtime, title) values($tt, ‘”.$title.”‘)”;
//print “SQL: “.$sql.”
“;
$res = mysql_query($sql);
if (FALSE == $res) {
echo “insert failed!/n”;
}
$i++;
}
}
mysql_close();
$etime = getmicrotime();
$runTime = round($etime – $btime, 4);
echo “runTime: “.$runTime.”/r/n
“;
?>
单独执行php连接MySQL，单条连接添加1000条记录需要：0.9s左右
php操作memcache的程序：
include_once(“gettime.php”);
$btime = getmicrotime();
//杩
