RubyGems的和捆紮機：慢速啓動

編輯：有點不同（和更少）的瓶頸用捆紮機1.0.9代替1.0.3。RubyGems的和捆紮機：慢速啓動

我對Rails的的慢啓動時間非常惱火（因爲我反覆運行測試），所以我試圖找出使用poor-man's profiling的罪魁禍首，通過運行rails console --help（它加載我所有的寶石）反覆，擊中Ctrl + C，然後查看堆棧跟蹤。

從像 active_support和朋友明顯的罪魁禍首

除了被加載，在某些時候（可能是10％左右），輸出類似於此：

$ rails console --help

    from <internal:lib/rubygems/custom_require>:29:in `require' 
    from script/rails:5:in `<main>'

如此看來，相當長的一段時間花費加載gemspecs。

是否有某種方式來加速這個嗎？骯髒的黑客也是讚賞 - 我只想運行我的測試套件沒有（很多）延遲。

捆綁1.0.3真的在我看來馬車。安裝最新的，我認爲它的1.0.9。 – 2011-01-27 21:37:15

啊，運行`bundle update`時它不會被更新。當然，我猜。所以我跑了`sudo gem update bundler`，現在我的版本是1.0.9。再試一次，它看起來可能稍微快一些，瓶頸現在在`rubygems`包中。我會在一秒內更新這個問題。 – 2011-01-27 21:51:38

你試過spork？

更新到這一點：tconsole實在是太酷，如果你正在使用MINITEST。
