Policy XACML PDP component
~~~~~~~~~~~~~~~~~~~~~~~~~~
Performance Test of Policy XACML PDP
++++++++++++++++++++++++++++++++++++
Summary
-------
The Performance test was executed by performing requests against the Policy RESTful APIs residing on the XACML PDP installed in the windriver lab to get policy decisions for monitoring and guard policy types. This was running on a kubernetes host having the following configuration:
- 16GB RAM
- 8 VCPU
- 160GB Disk
The performance test runs 10 simultaneous threads calling XACML PDP RESTful APIs to get decisions for Monitoring, Guard Min Max, and Guard Frequency Limiter policy types, with at duration of 6000 seconds. The test execution lasted approximately 50 minutes resulting in the following summary:
- 37,305 Healthcheck requests
- 33,716 Statistics requests
- 25,294 Monitoring decision requests
- 25,288 Guard Min Max decisions
- 25,286 Guard Frequency Limiter requests
The average throughput was about 9.8 transactions per second. CPU and memory usage along with a screenshot of the JMeter Summary Report are provided in this document.
