Use the RemoteCompression property to set the level of compression used for a remote session. This property only applies to remote sessions where the SessionType property is set to stRemote. The compression is specified as a Byte value between 0 and 9, with the default being 0, or none, and 6 being the best selection for size/speed. The default compression is ZLib, but can be replaced by using the TDBISAMEngine events for specifying a different type of compression. Please see the Compression and Customizing the Engine topics for more information.
This property can be changed while the session is connected so that you may adjust the level of compression for individual situations.
