There's also a overhead on the receiving side to uncompress the data.
However, if the size of the data becomes large, transmission overhead
outweighs the
compression/uncompression overhead.
That said, I think there is a necessary to measure the total time
difference from the
original data on the sending side and the time the receiver is actually
able to process the data.
Simply compressing the data also isn't too great if there is some
processing (e.g. context based
routing) between the sender and the receiver.
BTW, beside compression, there's also encryption overhead if one is needed.
