Ruby on rails 有人能就Rails内存消耗给我一些建议吗？

我现在正在开发一个Rails应用程序，它似乎要杀死我 我的iMac上的内存，直到我最终不得不重新启动。 我在OSX 10.6上有一个2.66 GHZ的处理器和4GB Ram

当我启动rails应用程序时，内存消耗显示如下 （ps aux | grep导轨）：

RSS的大小为158860KB 向localhost发出几次请求后，此数字会跳到：

Gavin      726   0.0 14.1  3031792 592888 s000  S+    9:27am 0:27.00  /Users/Gavin/.rvm/rubies/ree-1.8.7-2011.01/bin/ruby script/rails s 

592888 kb

随着开发的普遍使用，它一次又一次地上升 再次：

我正在用RVM运行REE ruby 1.8.7（2010-12-23 patchlevel 330）[i686-darwin10.6.0]，MBARI 0x6770，Ruby企业版2011.01

该应用程序使用的是Rails 3.0.6

该应用程序不是特别SQL密集型的，而且几乎没有 加载记录时不包含关联（在 架构）

我说这是内存泄漏还是有其他原因 我应该看看

有谁能给我一些建议，告诉我如何解决这个问题吗

谢谢

检查config/newrelic.yml以了解：

developer_mode: false|true

---

如果设置为“true”，则内存问题可能是这样。

看起来您有一些内存泄漏。尝试用内存探查器戳一下：

aasm在

cache\u classes=false时会很快泄漏内存（这是开发模式中的默认设置）。你确实使用了很多宝石，但我敢打赌aasm是幕后黑手

正如其他人所说，最好使用内存分析器
 啊哈！好的，所以newrelic.yml中的developer_模式被设置为true，但是改变它并重新启动仍然没有多大帮助。RSS仍在随着每个请求不断攀升。它只是在开发中泄漏内存？您可能有一些gem（ruby prof？）在内存中收集数据。看看如何确定谁应对内存泄漏负责：它在开发模式和生产模式下都在泄漏内存。。。但在开发模式下肯定更为严格。-aasm gem似乎存在内存问题，请尝试禁用它并查看它在没有它的情况下的性能。谢谢-我已签出memprof，但当我尝试加载它时，我得到错误：Ruby Mach-O文件的Magic不匹配请尝试从github安装，我就是这样安装的。git克隆；gem build memprof.gempec；sudogem安装memprof-*.gem；告诉我它是否对您有效。谢谢Roman，但仍然不走运：（我注意到当我将cache_类设置为“true”时，问题没有那么严重。有人能给我一些关于如何在没有memprof的情况下查找漏洞的建议吗？
