Improving Performance

Table M-2compares the relative processing cost of the three examples by looking at the approximate number of vector steps executed while processing the call. Assumption is that the first announcement is 3 seconds long and the second announcement is 4 seconds long.

When a call is queued for 5 minutes, the amount of vector steps drops dramatically when the amount of time between announcements is increased (Figure M-2),and drops even more when a second announcement is added, and the amount of time between announcements is increased again (Figure M-3).When an agent in split 1 is immediately available to answer the call, there is no difference in the amount of vector steps for the three examples.

Lookahead Interflow

Recommendation: Add a wait period between successive lookahead interflow attempts and make the waiting period as long as feasible.

The example in Figure M-4continuously attempts a lookahead interflow as long as the call is in queue or until a lookahead attempt succeeds.
