有人可以建议我了解Rails的内存消耗吗？

| 我目前正在开发一个Rails应用程序，这似乎很致命直到最终必须重新启动iMac上的内存。我在OSX 10.6上有一个2.66 GHZ处理器和4GB Ram。当我启动Rails应用程序时，内存消耗显示以下内容（ps aux | grep rails）：

Gavin      726   0.0  3.8  2590812 158860 s000  S+    9:27am 0:09.90  /Users/Gavin/.rvm/rubies/ree-1.8.7-2011.01/bin/ruby script/rails s

RSS的速度很酷，为158,860 kb 在对本地主机的一些请求之后，该数字跳升至：

592,888 kb！在一般的开发用途下，它会一次又一次地上升，再次：

我正在使用RVM运行REE 红宝石1.8.7（2010-12-23补丁程序级别330）[i686-darwin10.6.0]，MBARI 0x6770，Ruby企业版2011.01 该应用程序正在使用Rails 3.0.6 该应用程序不是特别密集的SQL，几乎有加载记录时不包括任何关联（建筑）。我是说这是内存泄漏还是其他问题？我应该看看吗？有人可以提供一些有关如何解决此问题的建议吗？谢谢！这是所有已知宝石的完整清单，以防万一那里的嫌疑犯：
