复杂的模型导致缓慢/差的性能

标签: php mysql codeigniter

下面你会找到一个名为getCalls的CodeIgniter模型,我从控制器$manager, $level, $department, $id

传递以下值

在内部我执行以下操作:

  1. 我检查登录用户的级别并将他/她指向正确的代码
  2. 我收集了名为$callInfo
  3. 的数组中视图中需要的所有数据

    我在数据库中通过所有已连接的列创建索引。

    调用处理此模型的控制器时,我遇到速度问题。 Firebug告诉我加载页面大约需要30秒。

    请注意,服务器性能和规格并不如您预期的那么好。这也是唯一的"复杂的屏幕"运行缓慢,我对下面的代码没有任何问题,只是一个速度问题。

    请注意,我通过$ .ajax调用该页面,您可以找到以下功能...

    请提出建议

    }
    

    这是ajax函数......

    $.ajax({
        type: 'GET',
        url: "<?php echo base_url() . 'boffice/dataTable/'; ?>" + type + "/" + arg,
        //data: {},//add variables
        beforeSend:function(){
            //this is were the loading image load
            $('.PreviewHere').append('<div class="preloading"><img src="<?php echo base_url() . "assets/images/loading.gif"; ?>" alt="تحميل" /></div>').show();
        },
        success: function(data){
            //successful request, do somthing with the data
            $('.PreviewHere').html(data).show();
            $(".preloading").remove();
        },
        error: function(){
            //failed request
        },
        datatype: 'html'
    })//ajax
