Description

One of the most consistent time-consuming spots of Thrift serialization and deserialization is string encoding. For some inscrutable reason, String.getBytes("UTF-8") is slow.

However, it's recently been brought to my attention that DataOutputStream's writeUTF method has a faster implementation of UTF-8 encoding and decoding. We should use this style of encoding.
