About data compression and the buffer age limit

Bandwidth usage is reduced by about 80% if compression is enabled. This assumes that the data rate is high enough to keep the buffer (64K) filled to have better compression ratio. For analog tags, the data rate is roughly 2000 values/second.

When the data rate is low, enabling compression may not be effective. To fill the buffer with low data rate, you can select the Wait to send incomplete packets option (BufferAgeLimit attribute) for the AppEngine configuration. This attribute is not applicable to replication.
