Rubyの下でMemcachedの2つのクライアントの対比

コード:

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はMemcache-clientよりずっと速いですね.この反射モデルに基づく中間部品は潜在力をよく発掘することができます.
