I have found performance issue when tried to deserialize big thrift binary message with enabled thrift_protocol php extension.
Messsage size was 10 mb and it took about 30 seconds to deserialize it.
When i have done debug of php extension and php library i have found that issue is because small read buffer is used in TBufferedTransport and i cannot change it from TBinarySerializer::deserialize method.
So i have added parameter $buffer_size to function thrift_protocol_read_binary from php extension.
And also this parameter i have added to method TBinarySerializer::deserialize from php library.
And i extended class Thrift\Transport\TMemoryBuffer by method putBack, so this class will be used for desearilization without TBufferedTransport warapper.
After these changes it takes less than a second to deserizlize message with 10 mb size id read buffer 512 kb.
