Which is small in size Twitting ? Json ? Website data passing thru var url ?

hello,
I would like to ask which has very small footprint
xively
HTTPclient
Webserver/client (using url var passing)
JSON
Twitting

Which is the smallest will consume less program mem and sram space ?
i have bigger code and i want to add cloud/web data logging
IMP NOTE: I am using Ethernet Shield with SD w5100 and I am using SD data logging on it...

Also passing data as DHT22 temp,humdity,RTC time, date, some functions(device) response on/off.... etc which get in 1 line.

I doubt there is much between them. The bulk of the work will be in the transport stack, which would be handled by the network interface rather than your sketch. All the protocols you're talking about are simple text based protocols. The only things that may trip you up are that if you use a protocol library that has features you don't need that may waste space, and if you're accessing a service that requires encryption or authentication then that would substantially increase the size and complexity of the client.

Thank you for the reply..
