Performance Metrics

No.	Metric	Description	Result	Comments
1	Single Threaded Response Time	Measure the execution time for onset and abatement in each use case with only a single policy executing	vCPE - 3 ms vFirewall - 2 ms vDNS - 8 ms VOLTE - 7 ms	The average time taken is calculated based on last 10,000 samples in audit.log file.
2	Single Threaded CPU Usage	CPU Usage for each use case when executing alone	~ 1%
3	Single Threaded Memory Usage	Memory Usage for each use case when executing alone	~ 100 MB
4	Maximum Simultaneous Executions	Measure the maximum number of simultaneous policy executions that can be achieved whilst maintaining system stability and resource utilization	2	The current size of source/sink topics is 10. And 1 onset message results to 5 messages in sink topic. Hence we can only run 2 simaltaneous thread and assert the values coming in sink topics.
