之前的测试，发现MongoDB的插入操作在使用PHP驱动时比使用mongo控制台更快。测试发现查询也是类似的情况
（以下测试都使用WT引擎）。

top的结果
索引查询速度大约 每秒1w次，mongod消耗CPU 65.2%，经过计算将1个cpu core用满可以达到1.5w/s（1/0.652）。
原来
test
.
php中的'uname'被改成了'_id'
原来
test_sel
.
php中的'uname'被改成了'_id'
查询top结果
索引查询速度大约每秒1.26w次，mongod消耗CPU 58.2% ，经过计算将1个cpu core用满可以达到2.2w/s（1/0.582）。

1. 插入数据
点击(此处)折叠或打开
- -bash-4.1$ cat test.php
- ?php
- header("Content-Type:text/html;charset=utf-8");
- //MongoDB有用户名密码并指定数据库admin
- $conn = new Mongo("mongodb://127.0.0.1:27017/benchmark");
-
- $db = $conn->admin;
- //定制结果集(表名things)
- $collection = $db->members;
- //$time1 = xdebug_time_index();
-
- for($i=1;$i1000000;$i++){
- $user = array('uname' => 'chuchuchu_'.$i, 'name' => '褚褚褚', 'password' => 'e10adc3949ba59abbe56e057f20f883e', 'email' => 'dhaig@yahoo.com.cn');
- $collection->insert($user);
- }
-
- $conn->close();
- //$time2 = xdebug_time_index();
- //echo "MongoDB响应时间为：".(time2−time1)."秒";
- ?>
-
- -bash-4.1$ time php test.php
-
-
- real 1m45.062s
- user 0m22.609s
- sys 0m12.569s
2. 建索引
点击(此处)折叠或打开
- -bash-4.1$ mongo benchmark
- ...
- > use admin
- switched to db admin
- > db.members.ensureIndex({uname:1})
- {
- "createdCollectionAutomatically" : false,
- "numIndexesBefore" : 1,
- "numIndexesAfter" : 2,
- "ok" : 1
- }
3.单点索引查询
点击(此处)折叠或打开
- -bash-4.1$ cat test_sel.php
- ?php
- header("Content-Type:text/html;charset=utf-8");
- $conn = new Mongo("mongodb://127.0.0.1:27017/benchmark");
-
- $db = $conn->admin;
- $collection = $db->members;
-
- for($i=1;$i1000000;$i++){
- $query = array( 'uname' => 'chuchuchu_'.$i);
- $cursor = $collection->find( $query );
- while( $cursor->hasNext() ) {
- $var=$cursor->getNext();
- }
- }
-
- $conn->close();
-
- ?>
-
- -bash-4.1$ time php test_sel.php
-
- real 1m42.998s
- user 0m22.888s
- sys 0m13.160s

4. 一级索引的测试
上面是二级索引的测试，那么"_id"的一级索引，性能会不会还有提升空间呢？也测一下看看。4.1 先把之前是数据删掉。

- -bash-4.1$ mongo benchmark
- ...
- > use admin
- switched to db admin
- > db.members.drop()
- true
