Question

I have the following object:

public partial class Game
{
    public bool Finished { get; set; }

    public Guid GameGUID { get; set; }

    public long GameID { get; set; }

    public bool GameSetup { get; set; }

    public Nullable<int> MaximumCardsInDeck { get; set; }

    public Player Player { get; set; }

    public Player Player1 { get; set; }

    public bool Player1Connected { get; set; }

    public bool Player1EnvironmentSetup { get; set; }

    public long Player1ID { get; set; }

    public int Player1Won { get; set; }

    public bool Player2Connected { get; set; }

    public bool Player2EnvironmentSetup { get; set; }

    public long Player2ID { get; set; }

    public int Player2Won { get; set; }

    public int Round { get; set; }

    public Nullable<int> RoundsToWin { get; set; }

    public bool Started { get; set; }

    public string StateXML { get; set; }

    public Nullable<DateTime> TimeEnded { get; set; }

    public Nullable<int> TimeLimitPerTurn { get; set; }

    public byte[] TimeStamp { get; set; }

    public Nullable<DateTime> TimeStarted { get; set; }    
}

This class gonna be filled with some test data.

I need the to compare the Performance of different Serializers used by the different forms of bindings for WCF Services:

• basicHttpBinding => SoapFormatter (TextFormatter?)
  
• binaryBinding => BinaryFormatter
  
• XMLFormatter
  

What i need to do in detail is:

• Get to now the size of the Object being serialized
  
• Get to now the size after serizlization
  
• Time to serialize
  
• Time to deserialize
  

I already tried some stuff, but i am struggling a bit.
Maybe there is already some simple code for this kind of measurement.

Answer 1

OK; I’ll bite… here’s some raw serializer metrics (emph: you may need to consider base-64/MTOM to get overall bandwidth requirements, plus whatever fixed overheads (both space and CPU) that WCF adds), however; results first:

BinaryFormatter
Length: 1314
Serialize: 6746
Deserialize: 6268

XmlSerializer
Length: 1049
Serialize: 3282
Deserialize: 5132

DataContractSerializer
Length: 911
Serialize: 1411
Deserialize: 4380

NetDataContractSerializer
Length: 1139
Serialize: 2014
Deserialize: 5645

JavaScriptSerializer
Length: 528
Serialize: 12050
Deserialize: 30558

(protobuf-net v2)
Length: 112
Serialize: 217
Deserialize: 250

(so I conclude protobuf-net v2 the winner…)

Numbers updated with .NET 4.5 and current library builds, on a newer machine:

BinaryFormatter
Length: 1313
Serialize: 2786
Deserialize: 2407

XmlSerializer
Length: 1049
Serialize: 1265
Deserialize: 2165

DataContractSerializer
Length: 911
Serialize: 574
Deserialize: 2011

NetDataContractSerializer
Length: 1138
Serialize: 850
Deserialize: 2535

JavaScriptSerializer
Length: 528
Serialize: 8660
Deserialize: 8468

(protobuf-net v2)
Length: 112
Serialize: 78
Deserialize: 134

with test rig (compiled with optimizations, run at command line):

(and note I had to invent the Player class and some sample data):
