Josce,

The time savings you are seeing is not the result of data compression
but rather the fact that the dataset is being built/collected locally
and then sent over the wire.

Thus, the normal row read/fetch exchange/conversation between the client
and the server is occuring on the proxy server (ie. on the local
network) without the normal delay of WAN/Internet based conversation.

The same performance benefit will be seeing using any application server
based solution, whether data compression is actually employed.
