什么是最快的Ruby记录器实现？

我想找到 Ruby提供的最快的记录器.我的直觉告诉我,系统日志会赢得这场比赛.但我的直觉似乎是错误的. Syslog是我测试的三个记录器中最慢的.我正在使用我的MacBook Pro,OSX 10.6(Snow Leopard),Intel Core2 Duo,4GB内存和MacPorts构建的Ruby 1.8.7.难道我做错了什么？或者Ruby的syslog实现那么慢？如果他们与我的不同,请随意发布您的结果.您也可以将您喜欢的Ruby记录器添加到基准测试中.我的目标是找到最快的记录器.我只对纯粹的性能(吞吐量)感兴趣.这里不关心多目标日志记录等功能.

# loggers_bench.rb

require 'rbench'
require 'activesupport'
require 'syslog'
require 'logger'

buffered = ActiveSupport::BufferedLogger.new('buffered.log')
logger   = Logger.new('logger.log')
syslog   = Syslog.open('rb_syslog')

TIMES = 10_000

RBench.run(TIMES) do
  column :syslog,:title => 'Syslog'
  column :logger,:title => 'Logger'
  column :buffered,:title => 'ActiveSuppoort::BufferedLogger'


  report '#info' do
    syslog {
      300.times do |i|
        syslog.info "hello #{i}"
      end
    }

    logger {
      300.times do |i|
        logger.info "#{Time.now} logging_logger[Process.pid]:  INFO  logging_logger : hello #{i}"
      end
    }
    buffered {
      300.times do |i|
        buffered.info "#{Time.now} logging_logger[Process.pid]:  INFO  logging_logger : hello #{i}"
      end
    }

  end
end

# > RUBYOPT=rubygems ruby loggers_bench.rb 
#                Syslog |  Logger | ActiveSuppoort::BufferedLogger|
# -----------------------------------------------------------------
# #info         158.316 | 117.882 |                        98.707 |

请注意,我只使用了更简单的形式：“hello#{i}”用于Syslog(理论上这应该更快,但事实并非如此).此外,我的Mac的默认syslogd似乎有一个有限的消息配额(500 /秒).系统日志中不时生成以下消息：

*** process 1962 exceeded 500 log message per second limit  -  remaining messages this second discarded ***
