您将在下面找到一个名为 CodeIgniter 的模型getCalls，我从控制器向其传递以下值$manager, $level, $department, $id
在里面我做了以下动作：
- 我检查登录用户的级别并将他/她指向正确的代码
- 我将所有需要在视图中的数据收集在一个名为的数组中
$callInfo
我在数据库中为所有连接的列创建了一个索引。
调用处理此模型的控制器时，我遇到了速度问题。Firebug 告诉我加载页面大约需要 30 秒。
请注意，服务器性能和规格不如您预期的那么好。这也是唯一一个运行缓慢的“复杂屏幕”，我对下面的代码没有任何问题，只是速度问题。
请注意，我通过 $.ajax 调用该页面，您可以在下面找到函数...
请指教
