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. ....

To copy to clipboard, switch view to plain text mode 

but is it the fastes way?

thank u ; )

Define what you mean by "fastest".

[Qiieha]

I mean speedy...

[wysota]

In terms of writing code, data transfer or what else?

[Qiieha]

sorry, I mean data transfer...

[wysota]

The fastest way is to develop your own binary protocol that will only transfer information that is really required, making use of some implicit domain knowledge like default values of fields in particular objects.

By the way, next time please post such questions on "General Programming" forum.

Should I use the Hessian Protocol?

[wysota]

You can use any protocol you want. But like I said, if you want "fastest" then you need your own protocol.

[Qiieha]

so there is a simple protocol

size //the socket knows, if all data is here
whatfor //command
data //the map f.e

size //the socket knows, if all data is here
whatfor //command
data //the map f.e

To copy to clipboard, switch view to plain text mode 

Can u show me a common protocol for a QMap<QString,QString>, please.

[wysota]

No, I can't. You need to develop it on your own considering your particular application needs. It's not something you can do in two minutes.

I never worked with binary protocols...
