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

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();
 - //
 - $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++;
 - }
 - //
 - $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:
- 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:
- $id = $_GET['id'];
 - $type = $_GET['type'];
 - $json_data = $_GET['data'];
 - var_dump($_GET);
 - //
 - $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:
- 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:
- 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:
- 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。
