What gain is obtained by compression?

Precisions

The essential exchanges should make it possible to reduce the volume of transfers. Minification of exchanges and compression of data exchanged allows to reduce these volumes. However, the compression and decompression operations require the execution of processes which can cancel out the benefit of the compression of exchanges.
