Factors affecting performance
The performance of the Communication Control Toolkit server depends on a
number of factors, including
number of resources (terminals, addresses, and users)
number of clients
number of calls per hour, call duration, and call complexity—Transfers,
conferencing, and attached caller-entered data all increase call complexity,
and, therefore, the resources required to process a call.
amount of call-attached data (see the following section)
hardware configuration (processor speed, memory, and disk space
available)—For more information about hardware platforms, see
"Hardware requirements" on page 46.
the type of solution (TAPI, IPML, or both)—A system running both TAPI
and IPML requires more system resources than a system running only TAPI
or IPML.
debugging and logging activities
Call-attached data
The amount of data attached to a call has a significant impact on performance.
Attached data that affects performance includes both TAPI data and IVR data.
Communication Control Toolkit handles a maximum of 4096 bytes of attached
data (TAPI + IVR) per call. The default call data size allowed per call is 512
bytes. To optimize performance, use the Communication Control Toolkit snap-in
utility to set the call data size to match your actual call data requirements (for
detailed instructions, see the Installation and Maintenance Guide). If the call
data size is set higher than your requirements, performance suffers because
unnecessary memory is allocated for each call.
