新しいscriptとして、`script/performance/request`というものが
新たに加わったみたいです。
pre>>
h% ./script/performance/request --help
USAGE: ./script/performance/request [options] [session script path]
-n, --times [0000] How many requests to process. Defaults to 100.
-b, --benchmark Benchmark instead of profiling
--open [CMD] Command to open profile results. Defaults to "open %s &"
-h, --help Show this help
<<--
ふむふむ。ベンチマーク系のスクリプトのようですね。

[**New in Rails: a request profiler for profiling your app**](http://blog.codefront.net/2007/10/26/new-in-rails-a-request-profiler-for-profiling-your-app/)
>Jeremy Kemper (aka bitsweat) committed a very useful tool into the Rails trunk not too long ago: a request profiler! It’s a human-friendly wrapper script around the ruby-prof library, a nice ruby code profiler, that lets you run multiple requests against a URI in your application and get a detailed code profile report in text and HTML.
おーなるほど。前回のRails勉強会で紹介した ruby-prof を
human-friendlyにしてくれるツールですか。これは面白そうですね。
試してみようと思って触ってみたら、上のサイトで紹介されてる
ものと、Rails 2.0で入ったものは若干インターフェイスが違う模様。

**Action Pack: New request profiler**
Figuring out where your bottlenecks are with real usage can be tough, but we just made it a whole lot easier with the new request profiler that can follow an entire usage script and report on the aggregate findings. You use it like this:
$ cat login_session.rb
get_with_redirect '/'
say "GET / => #{path}"
post_with_redirect '/sessions', :username => 'john', :password => 'doe'
say "POST /sessions => #{path}"
$ ./script/performance/request -n 10 login_session.rb
And you get a thorough breakdown in HTML and text on where time was spent and you’ll have a good idea on where to look for speeding up the application.

なにやらIntegrationTestのコードのようなものを記述したスクリプト
を用意して、そのpathを渡せば良いみたいです。
