Fastest way to transfer Data over tcp

[Qiieha]

Hi,
Maybe you can help me...

What is the fastest way to transmit Objects of classes over Tcp. I know Xml and I can comprime it,

f.e:

<Map>
<Entry>
<Key>45</Key>
<Value>
<Object>
<Member1>...</Member1>
<Member2>...</Member2>
...
</Object>
</Value>
</Entry>
etc. ....

<Map>
<Entry>
<Key>45</Key>
<Value>
<Object>
<Member1>...</Member1>
<Member2>...</Member2>
...
</Object>
</Value>
</Entry>
etc. ....
