This object reports the average time reduced, in milliseconds, for encrypted MAPI connections due to optimizations performed by the MAPI AO since it was started, with discontinuities marked by cwoAoStatsLastResetTime. Comparing this value to the unencrypted equivalent lets an administrator see whether encrypted MAPI sessions get as much benefit from the AO's optimizations as plaintext sessions do. For example, a much smaller reduction here than for unencrypted connections would suggest encryption is limiting how much the MAPI AO can optimize that traffic.
