Question

我们的Rails 4.2应用程序在Ubuntu 14.04服务器上运行254MB物理内存。 Ruby应用程序通常占用大量内存。然而254MB似乎仍然很多。

以下是该应用的Gemfile。 :path的所有宝石都是我们自己开发的引擎。有没有办法通过更好的编码实践来减少物理内存占用？

我们的独角兽工作者平均拥有260MB的RSS，而我们的gemlist比你的更长。我不知道你在那里拥有的所有宝石，但是你可以尝试使用ObjectSpace.count_objects追踪大量分配（在需要库之前和之后进行测量）。

虽然保存的RAM总是很好，但我认为250 MB是可以的。 Rails在内存中保持很多东西请求独立。

Rails 4.2应用程序是否占用了太多内存？
