  测试结果为(单位豪秒):
  手机环境:魅族MX2
  1) wire 1.5.1 ,网址 https://github.com/square/wire
  avg: 1860~1907 , 小值约为1500左右,极少出现, 全过程随机分布
  avg deserializeTime: 9~10, 小值约为5,极少出现,全过程随机分布
  2) protostuff 1.0.8 ,网址 https://code.google.com/p/protostuff/
  avg: 1100~1150,非常稳定 , 小值约为450左右,主要集中在前几次循环,循环10次后稳定在11XX左右,偶有600~800的情况,多次重复测试情况基本一致,观察自动GC并无内存泄漏的问题, 暂时不确定速度变化的原因.
  avg deserializeTime: 6, 小值约为3,极少出现,主要集中在刚开始,绝大多数为5,偶有达到16的情况.
  分析: wire的性能明显比不上protostuff, 速度也不太稳定,起落较大.  考虑到protostuff的开发模式是普通的pojo方式,比较方便,不像protobuff和wire的builder方式,超麻烦. 所以终推荐不是逻辑超复杂的企业app都使用protostuff .
