MySQL下MySQL-udf-http效率测试小记

这篇文章主要为大家详细介绍了MySQL下MySQL-udf-http效率测试小记，具有一定的参考价值，可以用来参考一下。

感兴趣的小伙伴，下面一起跟随四海网的小编小韵来看看吧！

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

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：

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

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：

代码如下:

 
<?php 
$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."<br>"; 
$res = mysql_query($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."<br>"; 
$res = mysql_query($sql); 
if (FALSE == $res) { 
echo "insert failed!\n"; 
} 
$i++; 
} 
} 
mysql_close(); 
$etime = getmicrotime(); 
$runTime = round($etime - $btime, 4); 
echo "runTime: ".$runTime."\r\n<br>"; 
?> 

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：

代码如下:

 
<?php 
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<br>"; 
?> 

单条连接添加1000条记录，需要0.8s左右，
创建触发器：

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：

代码如下:

 
<?php 
$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：

代码如下:

 
<?php 
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<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：

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：

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。
