Enabling compression for one connection or all connections, and adjusting the minimum size limit at which packets are compressed can offer significant improvements to performance under some circumstances.

To determine if enabling compression is beneficial, conduct a performance analysis on your network and using your application before using communication compression in a production environment.

Enabling compression increases the quantity of information stored in data packets, thereby reducing the number of packets required to transmit a particular set of data. By reducing the number of packets, the data can be transmitted more quickly.

Specifying the compression threshold allows you to choose the minimum size of data packets that you want compressed. The optimal value for the compression threshold may be affected by a variety of factors, including the type and speed of network you are using.

The use of file-level or disk-level compression for database and log files is not recommended since the compression layer may significantly increase the cost of IO operations.
