Ruby下Memcached两个客户端的对比

代码:

require "rubygems"
require 'eventmachine'
require "benchmark"
require "memcache"

cache_proc = proc{|cache,n|
  proc{
    n.times do |t|
      cache.set "a", 'hello'
      cache.set "b", 'hi'
      cache.set "c", 'how are you?'
      cache.set "d", ''

      # => EM client's get() must require a block,nnd.
      cache.get("a"){}
      cache.get("missing"){}
      cache.set("missing", 'abc')
      cache.get("missing"){}
      cache.delete("missing")
      cache.get("missing"){}
    end
    }
  }

# => memcache-client v1.7.0
cache_client = MemCache.new('localhost:10001')

# => Eventmachine Memcache Protocol
EM.run{
    cache_em = EM::P::Memcache.connect 'localhost', 10001
    Benchmark.bmbm do |x|
      x.report('EM',&cache_proc.call(cache_em,10000))
      x.report('memcache-client',&cache_proc.call(cache_client,10000))
    end
  }

Eventmachine要比Memcache-client快好多啊,这个基于反射模型的中间件可以好好的发掘下潜力了.
