ruby-prof

ruby-prof是比较强大的，支持cpu，内存使用，对象分配等等的性能分析，而且提供了很多友好的输出格式，不仅仅是有基于文字，html的格式，还能输出graphviz格式的dot文件。

require 'ruby-prof'RubyProf.start# 这里写入要进行性能剖析的代码result = RubyProf.stop# 选择一个Printerprinter = RubyProf::FlatPrinter.new(result)printer.print(STDOUT)

#代码示例require 'ruby-prof'def perf_test  if params[:__t]    RubyProf.start    yield    result = RubyProf.stop    printer = RubyProf::GraphPrinter.new(result)    printer  else    yield  endenddef hi  100_000.times { }enddef hello  10_000.times { }endRubyProf.starthihelloresult = RubyProf.stopprinter = RubyProf::GraphPrinter.new(result)printer.print(STDOUT, {})
