有人可以建议我对Rails内存消耗

Question

我目前正在开发一个Rails应用程序，这个应用程序似乎很无聊直到我不得不重新启动我的iMac。我在OSX 10.6上有一个2.66 GHZ的处理器和4GB的内存。

当我启动rails应用程序时，内存消耗显示如下(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的大小为158,860 kb在向localhost发出几个请求后，这个数字上升到:

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 ! !

随着一般的开发使用，它会一次又一次地上升再次:

Gavin      726   1.5 25.0  3487516 1050180 s000  S+    9:27am 0:59.29 /Users/Gavin/.rvm/rubies/ree-1.8.7-2011.01/bin/ruby script/rails s 

我正在使用RVM运行REEruby 1.8.7 (2010-12-23 patchlevel 330) [i686-darwin10.6.0]0x6770, Ruby企业版2011.01

应用程序使用Rails 3.0.6

应用程序不是特别SQL密集，几乎有加载记录时不包含关联(在体系结构)。

我说这是内存泄漏还是有其他东西是正确的吗我应该看什么?

谁能给我一些建议，我该如何解决这个问题?

谢谢!

Answer 1

当cache_classes = false(这是开发模式中的默认值)时，aasm会非常快地泄漏内存。你确实用了很多宝石，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。

Answer 2

看起来您有一些内存泄漏。尝试使用内存分析器:https://github.com/ice799/memprof

Answer 3

检查config/newrelic。yml:

developer_mode: false|true

如果设置为"true"，那么内存问题可能是这样的
