mysql下mysql-udf-http效率测试小记

看到张宴的博客上关于"http/rest客户端的文章"，怎样安装啥的直接都跳过，下面直接进入测试阶段，测试环境：虚拟机

复制代码 代码如下:

[root@localhost ~]# uname -a

Linux sunss 2.6.18-128.el5 #1 SMP Wed Jan 21 10:44:23 EST 2009 i686 i686 i386 GNU/Linux

内存和交换分区：

复制代码 代码如下:

[root@localhost ~]# free -m

total used free shared buffers cached

Mem: 376 363 13 0 23 105

-/+ buffers/cache: 233 142

Swap: 1023 133 890

mysql：

[root@localhost ~]# mysql -u root -p

Enter password:

Your MySQL connection id is 57

Server version: 5.1.26-rc-log Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql>

使用的表结构：

复制代码 代码如下:

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：

复制代码 代码如下:

$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：

复制代码 代码如下:

include_once("gettime.php");

$btime = getmicrotime();

//杩炴帴

$mem_host = "192.168.0.134";

$mem_port = "11311";

$timeout = 3600;

$i = 0;

$cnt = 1000;

while ($i < $cnt) {

$mem = new Memcache;

$mem->connect($mem_host, $mem_port) or die("Could not connect!");

$ret = $mem->set($i, "11111111111", 0, $timeout);

if (false == $ret) {

file_put_contents("insert_failed.log", "post failed!\n", FILE_APPEND);

}

$mem->close();

$i++;

}

//鍏抽棴杩炴帴

$etime = getmicrotime();

$runTime = round($etime - $btime, 4);

echo "runTime: ".$runTime."\r\n
";

?>

单条连接添加1000条记录，需要0.8s左右，

创建触发器：

复制代码 代码如下:

DELIMITER $$

DROP TRIGGER /*!50032 IF EXISTS */ `test`.`mytable_insert`$$

CREATE

/*!50017 DEFINER = 'root'@'localhost' */

TRIGGER `mytable_insert` AFTER INSERT ON `mytable`

FOR EACH ROW BEGIN

SET @tt_resu = (SELECT http_put(CONCAT('http://192.168.0.134/mem_ss.php?type=post&id=', NEW.id, "&data=", NEW.addtime), 11));

END;

$$

为触发器写个php更新memcache,代码如下：

复制代码 代码如下:

$id = $_GET['id'];

$type = $_GET['type'];

$json_data = $_GET['data'];

var_dump($_GET);

//杩炴帴

$mem_host = "192.168.0.134";

$mem_port = "11211";

$timeout = 3600;

$mem = new Memcache;

$mem->connect($mem_host, $mem_port) or die("Could not connect!");

if ("get" == $type ) {

$val = $mem->get($id);

echo $val;

//$arr = jsonDecode($val,'utf-8');

//print_r($arr);

} else if ("put" == $type) {

$ret = $mem->replace($id, $json_data, 0, $timeout);

if (false == $ret) {

file_put_contents("replace_failed.log", "replace failed!\n", FILE_APPEND);

}

} else if ("delete" == $type) {

$ret = $mem->delete($id);

if (false == $ret) {

file_put_contents("delete_failed.log", "delete failed!\n", FILE_APPEND);

}

} else if ("post" == $type) {

$ret = $mem->set($id, $json_data, 0, $timeout);

if (false == $ret) {

file_put_contents("post_failed.log", "post failed!\n", FILE_APPEND);

}

}

$mem->close();

?>

使用php触发MySQL添加1000条记录，同时触发器触动php更新memcache，使用时间9s左右，

因为每次都关闭链接memcache，看是不是关闭链接导致慢，又写了一个程序：

复制代码 代码如下:

include_once("gettime.php");

$btime = getmicrotime();

//连接

$mem_host = "192.168.0.134";

$mem_port = "11311";

$timeout = 3600;

$i = 0;

$cnt = 1000;

while ($i < $cnt) {

$mem = new Memcache;

$mem->connect($mem_host, $mem_port) or die("Could not connect!");

$ret = $mem->set($i, "11111111111", 0, 3600);

if (false == $ret) {

file_put_contents("insert_failed.log", "post failed!\n", FILE_APPEND);

}

$mem->close();

$i++;

}

//关闭连接

$etime = getmicrotime();

$runTime = round($etime - $btime, 4);

echo "runTime: ".$runTime."\r\n
";

?>

耗时0.9s左右，比一个连接慢不了多少。

为了定位是触发器慢还是http_put慢，创建一个临时表

tmp_mytable，表结构如下：

复制代码 代码如下:

CREATE TABLE `mytable` (

`id` int(10) NOT NULL AUTO_INCREMENT,

`addtime` int(10) NOT NULL,

`title` varchar(255) NOT NULL

) ENGINE=MyISAM DEFAULT CHARSET=utf8;

再次修改触发器，如下：

复制代码 代码如下:

DELIMITER $$

DROP TRIGGER /*!50032 IF EXISTS */ `test`.`mytable_insert`$$

CREATE

/*!50017 DEFINER = 'root'@'localhost' */

TRIGGER `mytable_insert` AFTER INSERT ON `mytable`

FOR EACH ROW BEGIN

insert into tmp_mytable values(NEW.id,NEW.addtime,NEW.title);

END;

$$

再次用php向MySQL中添加1000条记录，消耗时间0.7s左右，证明效率消耗在http_put，也就是mysql-udf-http慢。

不知道我的测试有错没？还请正在使用mysql-udf-http的高手，或者对mysql-udf-http有研究的高手指教。相关阅读:
