Rails Admin 在生产中渲染异常缓慢

Question

我正在运行 Rails Admin，并使用 docker 在生产环境中使用 Rails API。由于某种原因，渲染速度非常慢。一个简单的页面加载需要 15 秒，看起来布局的渲染需要非常长的时间。

我是否忘记在 docker 构建过程中的某处编译资产，这是造成这种情况的原因吗？

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"

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
