Time required to add observer

Q. I observed that adding an observer to terminal takes more than 1 second.
Its quite a slow operation.

I have thousand terminals in my setup.

Initializing JTAPI application with these thousand terminals take lot of time.

I am using two approaches here:

1. To register terminals under a user

2. To create terminal using super provider

Both of the aforementioned approaches require more than 1 second to add observer per terminal.

How I can minimize the time required to add observer.

Check the CPU on application server, network latency between app server and CUCM, CPU utilization on CUCM.
