title: Thrift php lib performance issue
body: <p>I recently use php thrift client to call some service implemented by java thrift server.</p>
  
  <p>But I found that when I transfer a large amount of complex data, php spent a lot of time serialize and deserialize data because of tens of thousands of <code>TBinaryProtocol::readXXX()</code> or <code>TBinaryProtocol::writeXXX()</code>
   calls.</p>
  
  <p>Any good idea to optimize this?</p>
