RubyGems的和捆扎机：慢速启动

编辑：有点不同（和更少）的瓶颈用捆扎机1.0.9代替1.0.3。RubyGems的和捆扎机：慢速启动

我对Rails的的慢启动时间非常恼火（因为我反复运行测试），所以我试图找出使用poor-man's profiling的罪魁祸首，通过运行rails console --help（它加载我所有的宝石）反复，击中Ctrl + C，然后查看堆栈跟踪。

从像 active_support和朋友明显的罪魁祸首

除了被加载，在某些时候（可能是10％左右），输出类似于此：

$ rails console --help

如此看来，相当长的一段时间花费加载gemspecs。

是否有某种方式来加速这个吗？肮脏的黑客也是赞赏 - 我只想运行我的测试套件没有（很多）延迟。

捆绑1.0.3真的在我看来马车。安装最新的，我认为它的1.0.9。 – 2011-01-27 21:37:15

啊，运行`bundle update`时它不会被更新。当然，我猜。所以我跑了`sudo gem update bundler`，现在我的版本是1.0.9。再试一次，它看起来可能稍微快一些，瓶颈现在在`rubygems`包中。我会在一秒内更新这个问题。 – 2011-01-27 21:51:38

你试过spork？

更新到这一点：tconsole实在是太酷，如果你正在使用MINITEST。
