Rails 4.2應用程序是否佔用太多內存？

Question

我們的Rails 4.2應用程序正在運行254MB物理內存在ubuntu 14.04服務器上運行。 Ruby應用通常有很大的內存佔用。然而254MB仍然看起來很多。以下是該應用的Gemfile。所有與:path寶石都是我們自己開發的引擎。有更好的編碼實踐來減少物理內存佔用？非常感謝。

我們的獨角獸工作者平均擁有260MB的RSS，而我們的gemlist比你的要長。我不知道你在那裏擁有的所有寶石，但你可以嘗試用ObjectSpace.count_objects（需要圖書館之前和之後的措施）追蹤巨大的分配。

雖然保存的內存總是很好，但我認爲250 MB是可以的。 Rails在內存中保持很多獨立的請求。
