哪个是最好的图形化 Ruby 分析器？
到目前为止，我发现的最佳匹配是从命令行使用 ruby-prof 并尝试从那里猜测图形读数。
require 'ruby-prof'
# Profile the code
RubyProf.start
...
[code to profile]
...
result = RubyProf.stop
# Print a flat profile to text
printer = RubyProf::FlatPrinter.new(result)
printer.print(STDOUT)

这种方法的主要问题是您必须修改代码才能查看分析结果，并且可读性不太好。
我还尝试过一些 IDE：RubyMine、Aptana 和 Netbeans，但没有人拥有合适的图形界面来分析代码。
有什么推荐吗？
The best match that I have found until now is to use ruby-prof from command line and try to guess the graph reading from there.
require 'ruby-prof'
# Profile the code
RubyProf.start
...
[code to profile]
...
result = RubyProf.stop
# Print a flat profile to text
printer = RubyProf::FlatPrinter.new(result)
printer.print(STDOUT)
https://github.com/rdp/ruby-prof
The main problem with this approach is that you have to modify your code to see the profiling and is not very readable.
Also I have tried if some IDEs: RubyMine, Aptana and Netbeans and no one has a proper graphical interface to profile code.
Any recommendation?
