Cpu Loading Measurement Data - Nortel Symposium Agent Reference Manual

June 2001

CPU loading measurement data

Performance Monitor logs were collected during the testing for test cases 2
through 5. (The SA Server log file for Test Case 4 contained corrupted data and
therefore was not used. The corresponding TAPI log file was not corrupted and
could be used.) This data was analyzed and a simple model of Symposium Agent
CPU load as a function of call rate was derived.
Note: These calls were simple calls and had no other processing associated with
them.
The log data for the SA server and TAPI server are summarized below in the first
and second tables respectively:
