在运行Php 5.4的Linux MySQL 5.6服务器中,以下命令需要2-3秒

exec("mysql --host=$db_host --user=$db_user --password=$db_password $db_name < $sql_file"); 

在具有类似配置的窗口上,需要10-15秒.Windows机器有更多的RAM(16GB)和类似的硬盘驱动器.我安装了MySQL 5.6并没有进行配置更改.这是在Windows Server 2012上.

我可以更改哪些配置来解决此问题？

数据库文件创建了大约40个innodb表,其中包含非常少的插入.

编辑:这是我正在运行的文件:

更新:在Windows 8和7上它是3秒.但在Windows Server 2012上它是15秒以上.我禁用了System Center 2012,但没有任何区别.

更新2:

我也试过杀死除mysql和IIS之外的几乎所有服务,它仍然执行缓慢.Windows Server 2012中是否存在导致此速度变慢的问题？

更新3我尝试禁用写缓存缓冲区刷新,性能现在很好.

我没有必要在我测试的其他机器上执行此操作.这是否表明磁盘是如何设置的？

我试图找出节点如何映射回它们包含的字段用于学习目的.这是怎么做到的？

目标:按地区显示每个种族和年份的种族数据占总数的百分比.

问题:查询需要30分钟才能运行.我想把它降到10秒以下.还有另一种解决这个问题的策略是我没想到的吗？

查询:

SELECT field_data_field_district_id.field_district_id_value as district_id, year, race, ROUND(SUM(count)/(
SELECT SUM(count)
FROM school_data_race_ethnicity_raw as school_data_race_ethnicity_raw_inner
INNER JOIN field_data_field_school_id as field_data_field_school_id_inner ON field_data_field_school_id_inner.field_school_id_value = school_data_race_ethnicity_raw_inner.school_id

WHERE field_data_field_district_id_inner.field_district_id_value = field_data_field_district_id.field_district_id_value and
school_data_race_ethnicity_raw_inner.year = school_data_race_ethnicity_raw.year

INNER JOIN field_data_field_district_id ON field_data_field_district.field_district_nid = …

我在文档中找不到这个,但是:

max_input_time = -1

意味着没有限制？

我觉得很奇怪,这max_execution_time = 0是永远的.

但这-1意味着max_input_time什么？

当我做sudo gem install XYZ那个代码实际上去了哪里？用另一种语言用宝石写的宝石？

当我进行捆绑安装时,它会做什么？我通读了rails教程,但它似乎忽略了那些重要的细节.

如果我有一个1000x3000像素的图像,并且我使用负背景位置,这是如何工作的？

我认为通过向左移动209像素然后向上移动2个像素,然后显示实际剩下的部分,但它似乎与此相反.

我很难理解hook_theme()的作用.

我的理解是它与可以覆盖模板有关.

我在看:

  $theme_hooks = array(
    'poll_vote' => array(
      'template' => 'poll-vote',
      'render element' => 'form',
    ),
    'poll_choices' => array(
      'render element' => 'form',
    ),
    'poll_results' => array(
      'template' => 'poll-results',
      'variables' => array('raw_title' => NULL, 'results' => NULL, 'votes' => NULL, 'raw_links' => NULL, 'block' => NULL, 'nid' => NULL, 'vote' => NULL),
    ),
    'poll_bar' => array(
      'template' => 'poll-bar',
      'variables' => array('title' => NULL, 'votes' => NULL, 'total_votes' => NULL, 'vote' => NULL, 'block' => NULL), …

function example_module_node_view($node, $view_mode, $langcode)
{   
    $f =  drupal_get_form('example_module_form', $node);
    $node->content['data_collection_form'] = array('#value' => $f, '#weight' => 1); 
}

为什么表格不显示？难道我做错了什么？正在填充表单对象.我可以做#markup =>'Something'并且它有效.

我正在尝试使用ssl证书验证调试问题,并确定openssl获取返回错误路径的证书位置.(见下文)

我如何弄清楚如何设置它？我查看了php.ini文件,无法在任何地方找到此引用.

cmuench-air:bin cmuench$ ./php -r "print_r(openssl_get_cert_locations());"
