Title Body

I'm working on a compact framework application and need to boost performance. The app currently works offline by serializing objects to XML and storing them in a database. Using a profiling tool I could see this was quite a big overhead, slowing the app. I thought if I switched to a binary serialization the performance would increase, but because this is not supported in the compact framework I looked at protobuf-net. The serialization seems quicker, but deserialization much slower and the app is doing more deserializing than serializing. Should binary serialization should be faster and if so what I can do to speed up the performance? Here's a snippet of how I'm using both XML and binary: XML serialization: public string Serialize(T obj) { UTF8Encoding encoding = new UTF8Encoding(); XmlSerializer serializer = new XmlSerializer(typeof(T)); MemoryStream stream = new MemoryStream(); XmlTextWriter writer = new XmlTextWriter(stream, Encoding.UTF8); serializer.Serialize(stream, obj); stream = (MemoryStream)writer.BaseStream; return encoding.GetString(stream.ToArray(), 0, Convert.ToInt32(stream.Length)); } public T Deserialize(string xml) { UTF8Encoding encoding = new UTF8Encoding(); XmlSerializer serializer = new XmlSerializer(typeof(T)); MemoryStream stream = new MemoryStream(encoding.GetBytes(xml)); return (T)serializer.Deserialize(stream); } Protobuf-net Binary serialization: public byte[] Serialize(T obj) { byte[] raw; using (MemoryStream memoryStream = new MemoryStream()) { Serializer.Serialize(memoryStream, obj); raw = memoryStream.ToArray(); } return raw; } public T Deserialize(byte[] serializedType) { T obj; using (MemoryStream memoryStream = new MemoryStream(serializedType)) { obj = Serializer.Deserialize<T>(memoryStream); } return obj; }
