* Response times varied in the milliseconds range and any difference between CPU utilization with encryption and without encryption was insignificant.
The following screen shows Windows NT performance data for CPU utilization
without
port encryption.
The three spikes correspond to the initial connections of 500, 800, and 1,000 active user sessions. The period between these spikes represents the one-hour test duration.
The following screen shows Windows NT performance data for CPU utilization
with

Again, the three spikes correspond to the initial connections of 500, 800, and 1,000 active user sessions. The period between these spikes represents the one-hour test duration.
