Reduction ratio for MAPI is different between Client-side and Server-side Exindas

Problem

The Reduction Ratio percentage reported on the client-side Exinda is not the same as the percentage reported on the server-side Exinda.

Explanation

As the MAPI traffic passes through the client-side and server-side Exinda appliances, the traffic is decompressed and optimized at different points in the transaction. Because of the timing of the decompressing and optimizing, the appliances may report different reduction ratio percentages.
