Users can enable compression of communication packets using REC between E3 Server, Viewer, and Studio, by using the Compression level item.

Default value for this item is 0 (zero). If this item is not modified, the system automatically assumes that compression is disabled.

If this item is modified, any value between one and nine enables compression. Recommended value is 6 (six). Any values outside this range disable REC packet compression.

This configuration is applied only for compression of an E3 Server or a Viewer executing on a local computer. E3 Server, as well as Viewer, support packet decompression, regardless of their configurations.
