mysql的mysql-udf-http效率测试小记_MySQL

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

[root@localhost ~]# uname -a<br>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：

[root@localhost ~]# free -m<br>             total       used       free     shared    buffers     cached<br>Mem:           376        363         13          0         23        105<br>-/+ buffers/cache:        233        142<br>Swap:         1023        133        890

mysql：

[root@localhost ~]# mysql -u root -p<br>Enter password: <br>Welcome to the MySQL monitor.  Commands end with ; or /g.<br>Your MySQL connection id is 57<br>Server version: 5.1.26-rc-log Source distribution<br><br>Type 'help;' or '/h' for help. Type '/c' to clear the buffer.<br>mysql>

使用的表结构：

DROP TABLE IF EXISTS `mytable`;<br><br>CREATE TABLE `mytable` (<br>  `id` int(10) NOT NULL AUTO_INCREMENT,<br>  `addtime` int(10) NOT NULL,<br>  `title` varchar(255) NOT NULL,<br>  PRIMARY KEY (`id`)<br>) ENGINE=MyISAM DEFAULT CHARSET=utf8;

php操作MySQL的程序：

View Code

 1 <?php <br /> 2     $type = $_GET['type'];<br> 3     print_r($_GET);<br> 4     include_once("gettime.php");<br> 5     $btime = getmicrotime();<br> 6     $loop_cnt= 1000; //循环次数<br> 7     $db_host = '127.0.0.1'; //<br> 8     $db_user = 'sunss'; //<br> 9     $db_pass = '123456'; //<br>10     $db_name = 'test'; //<br>11     $db_link = mysql_connect($db_host, $db_user, $db_pass) or die("Connected failed: ".mysql_error()."/n");<br>12     mysql_query('set names utf8');<br>13     mysql_db_query($db_name, $db_link);<br>14     if ("put" == $type) {//修改<br>15     $i = 1;<br>16     while ($i 17         $title = "jkjkjkjkjkjkjkjkjkjkjkjkjk";<br>18         $tt    = time();<br>19         $sql = "update mytable set addtime=".$tt.",title='".$title."' where id='".$i."'";<br>20         $res = mysql_query($sql);<br>21         if (FALSE == $res) {<br>22         echo "update failed!/n";<br>23         }<br>24         $i++;<br>25     }<br>26     } else if ("delete" == $type) { //删除<br>27     $i = 1;<br>28     while ($i 29         $sql = "delete from mytable where id='".$i."'";<br>30        echo "delete sql: ".$sql."<br>";<br>31         $res = mysql_query($sql);<br>32         if (FALSE == $res) {<br>33         echo "delete failed!/n";<br>34         }<br>35         $i++;<br>36     }<br>37     <br>38     } else if ("post" == $type) { //添加<br>39     $i = 0;<br>40     while ($i 41         $title = "hahahahahahahahahahahahahahahahahaha";<br>42         $tt    = time();<br>43         $sql = "insert into mytable(addtime, title) values($tt, '".$title."')";<br>44         //print "SQL: ".$sql."<br>";<br>45         $res = mysql_query($sql);<br>46         if (FALSE == $res) {<br>47         echo "insert failed!/n";<br>48         }<br>49         $i++;<br>50     }<br>51     }<br>52     mysql_close();<br>53     $etime = getmicrotime();<br>54     $runTime = round($etime - $btime, 4);<br>55     echo "runTime: ".$runTime."/r/n<br>";<br>56 ?>

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：

View Code

 1 <?php <br /> 2     include_once("gettime.php");<br> 3     $btime = getmicrotime();<br> 4     //杩炴帴<br> 5     $mem_host = "192.168.0.134";<br> 6     $mem_port = "11311";<br> 7     $timeout  = 3600;<br> 8     $i = 0;<br> 9     $cnt = 1000;<br>10     while ($i 11     $mem = new Memcache;<br>12     $mem->connect($mem_host, $mem_port) or die("Could not connect!");<br>13     $ret = $mem->set($i, "11111111111", 0, $timeout);<br>14     if (false == $ret) {<br>15         file_put_contents("insert_failed.log", "post failed!/n", FILE_APPEND);<br>16     }<br>17     $mem->close();<br>18     $i++;<br>19     }<br>20 <br>21     //鍏抽棴杩炴帴<br>22     $etime = getmicrotime();<br>23     $runTime = round($etime - $btime, 4);<br>24     echo "runTime: ".$runTime."/r/n<br>";<br>25 ?>

单条连接添加1000条记录，需要0.8s左右，

创建触发器：

DELIMITER $$<br><br>DROP TRIGGER /*!50032 IF EXISTS */ `test`.`mytable_insert`$$<br><br>CREATE<br>    /*!50017 DEFINER = 'root'@'localhost' */<br>    TRIGGER `mytable_insert` AFTER INSERT ON `mytable` <br>    FOR EACH ROW BEGIN  <br>    SET @tt_resu = (SELECT http_put(CONCAT('http://192.168.0.134/mem_ss.php?type=post&id=', NEW.id, "&data=", NEW.addtime), 11));<br>END;<br>$$

为触发器写个php更新memcache,代码如下：

View Code

<?php <br />    $id        = $_GET['id'];<br>    $type      = $_GET['type'];<br>    $json_data = $_GET['data'];<br>    var_dump($_GET);<br>    //杩炴帴<br>    $mem_host = "192.168.0.134";<br>    $mem_port = "11211";<br>    $timeout  = 3600;<br>    $mem = new Memcache;<br>    $mem->connect($mem_host, $mem_port) or die("Could not connect!");<br>    <br>    if ("get" == $type ) {<br>    $val = $mem->get($id);<br>    echo $val;<br>    //$arr = jsonDecode($val,'utf-8');<br>    //print_r($arr);<br>    } else if ("put" == $type) {<br>    $ret = $mem->replace($id, $json_data, 0, $timeout);<br>    if (false == $ret) {<br>        file_put_contents("replace_failed.log", "replace failed!/n", FILE_APPEND);<br>    } <br>    } else if ("delete" == $type) { <br>    $ret = $mem->delete($id);<br>    if (false == $ret) {<br>        file_put_contents("delete_failed.log", "delete failed!/n", FILE_APPEND);<br>    }<br>    } else if ("post" == $type) {<br>    $ret = $mem->set($id, $json_data, 0, $timeout);<br>    if (false == $ret) {<br>        file_put_contents("post_failed.log", "post failed!/n", FILE_APPEND);<br>    }<br>    }<br><br>    $mem->close();<br>?>

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：View Code

<?php <br />    include_once("gettime.php");<br>    $btime = getmicrotime();<br>    //连接<br>    $mem_host = "192.168.0.134";<br>    $mem_port = "11311";<br>    $timeout  = 3600;<br>    $i = 0;<br>    $cnt = 1000;<br>    while ($i     $mem = new Memcache;<br>    $mem->connect($mem_host, $mem_port) or die("Could not connect!");<br>    $ret = $mem->set($i, "11111111111", 0, 3600);<br>    if (false == $ret) {<br>        file_put_contents("insert_failed.log", "post failed!/n", FILE_APPEND);<br>    }<br>    $mem->close();<br>    $i++;<br>    }<br><br>    //关闭连接<br>    $etime = getmicrotime();<br>    $runTime = round($etime - $btime, 4);<br>    echo "runTime: ".$runTime."/r/n<br>";<br>?>

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：<br><pre class="brush:php;toolbar:false">CREATE TABLE `mytable` (<br>  `id` int(10) NOT NULL AUTO_INCREMENT,<br>  `addtime` int(10) NOT NULL,<br>  `title` varchar(255) NOT NULL<br>) ENGINE=MyISAM DEFAULT CHARSET=utf8;

再次修改触发器，如下：

DELIMITER $$<br><br>DROP TRIGGER /*!50032 IF EXISTS */ `test`.`mytable_insert`$$<br><br>CREATE<br>    /*!50017 DEFINER = 'root'@'localhost' */<br>    TRIGGER `mytable_insert` AFTER INSERT ON `mytable` <br>    FOR EACH ROW BEGIN  <br>     insert into tmp_mytable values(NEW.id,NEW.addtime,NEW.title);   <br>END;<br>$$

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。
