右下角有个source

下载

./configure


configure: error: “could not find memcached binary”

http://memcached.org/

下载memcache..

./configure

make && make install

http://monkey.org/~provos/libevent/ (可能需要libevent)

安装了memcached以后，继续configure libmemcached

./configure

make && make install

下载PHP memcached 支持

http://pecl.php.net/package/memcached

~phpbin/phpize

./configure –with-php-config=~phpbin/php-config

make && make install

改了php.ini后

phpinfo()输出:

memcached

memcached support enabled

Version 1.0.0

libmemcached version 0.37

Session support yes

igbinary support no

addServer(’10.10.10.50′, 11311);

function microtime_float()

{

list($usec, $sec) = explode(” “, microtime());

return ((float)$usec + (float)$sec);

}

$time_start = microtime_float();

for($i=0;$i<10000;$i++) { $m->set(‘int’, 99);

$m->set(‘string’, ‘a simple string’);

$m->set(‘array’, array(11, 12));

/* expire ‘object’ key in 5 minutes */

$m->set(‘object’, new stdclass, time() + 300);

//$m->get(‘int’);

//$m->get(‘string’);

//$m->get(‘array’);

//$m->get(‘object’);

}

$time_end = microtime_float();

$time = $time_end – $time_start;

echo “Did nothing in $time seconds\n”;

把第一行memcache改成memecached就能改了

我的实际测试结果

1万次读写 memcache:memcached 12:11

1万次只写，memcache:memcached 7:5

1万次只读 memcache:memcached 5.1:4.6

差距不大，而且memcached读取’object’这个key的时候居然报错了 Warning: Memcached::get(): unknown payload type in

这个应该是memcache写入的stdclass模式和memcached写入的格式不同，所以导致memcached读的时候出了问题。

总的来说libmemcached是全面胜出的，考虑到libmemcached还提供更多的接口，还是准备更换了！
