Rails Admin的生产速度异常慢

Question

我正在使用Rails API在docker生产环境中运行Rails Admin。由于某些原因，渲染速度非常慢。一个简单的页面加载需要15秒钟，看来布局的渲染要花费非常长的时间。

我是否忘了在Docker构建过程中的某个地方编译资产，这是造成这种情况的原因？

User Load (18.8ms)  SELECT "users".* FROM "users" ORDER BY users.id desc LIMIT $1 OFFSET $2  [["LIMIT", 20], ["OFFSET", 0]]
    (20.8ms)  SELECT COUNT(*) FROM "users"
    Rendered /usr/local/bundle/gems/rails_admin-2.0.2views/rails_admin/main/index.html.haml within layouts/rails_admin/application (Duration: 1559.2ms | Allocations: 49878)

根据Github上的this issue，您可以尝试像这样禁用统计信息

RailsAdmin.config do |c|
  c.actions do
    dashboard do
      statistics false
    end
  end
end
