Question

我正在使用Rails 3.0.7，kaminari gem。

我刚刚建立了一个简单的网站，包含SQLite数据库和100,000行数据，只有四列（ID，name，created_at，updated_at）。< / p>

这是我的控制者：

class HclinksController < ApplicationController
  # GET /hclinks
  # GET /hclinks.xml
  def index
    @hclinks = Hclink.page(params[:page])

    respond_to do |format|
      format.html # index.html.erb
      format.xml  { render :xml => @hclinks }
    end
  end
end

我搭建了它。

这是我的日志：

// THIS IS INDEX, WHICH SHOWS ALL THE LIST ITEMS
Started GET "/hclinks" for 127.0.0.1 at 2011-05-08 00:59:52 +0800
  Processing by HclinksController#index as HTML

// THIS IS THE RUBY ON RAILS WELCOME PAGE

Rendered hclinks/index.html.erb within layouts/application (1532.2ms)
Completed 200 OK in 1657ms (Views: 652.5ms | ActiveRecord: 975.9ms)

我想知道为什么列表需要这么长时间来回复...我应该如何修复它？谢谢！

Answer 1

这个日志输出是重新启动rails还是应用程序已经运行了一些请求？

如果这不是第一个请求，我会检查每个请求的加载时间是否增加。

如果是，则可能发生内存泄漏

页面索引需要花费太多时间来加载
