This report summarizes the results of performance and load testing of a server application. It includes details of 14 test cases conducted with varying numbers of virtual users, frame rates, and enhancement settings. The tests measured response times for key transactions and the impact of different parameter values on initial buffering time and frame playback. The report concludes that within the tested ranges, frame rate had more impact on performance than the enhancement setting.

1. Scenario Specification
Performance and load testing is normally performed in order to validate multi-client-server complex system. This load test scenario is based on …
The scenario was created in order to validate that the followings requirements have been met by the current version of the server application: …
The system topology that is relevant to the performance and load testing procedure was created …
The following pages provide the settings, results, and conclusions derived from the load tests, as specified.

2. Load Test Hardware Load test hardware requirements depend on mainly on the footprint of the virtual client that creates load on the EXAMPLE server side. In the EXAMPLE Web APP system, the client is a Web browser that buffers thousands of EXAMPLES. That creates rather a fat client with huge memory requirements. Running an EXAMPLE load test from CMD w/o JAVA GUI: On a 64-bit LINUX EXAMPLE workstation with 8 GB RAM, 10 concurrent virtual users are below the maximum, sizing approximately 2 GB JAVA.EXE process size. With EXAMPLE JAVA GUI: On a 64-bit LINUX EXAMPLE workstation with 8 GB RAM, approximately 5 concurrent virtual users are the maximum, sizing 4.0-4.5 GB JAVA.EXE process size, depending probably on the EXAMPLE size of the specific video frames that were buffered.

3. Load Test Software The selected load generation environment is:  Java Virtual Machine 64-bit on LINUX Ubuntu 14 64-bit,  JMeter version 2.11,  Standard and extra set of JMeter Plug-ins version 1.1.3. The Apache JMeter™ desktop application is open source software, a 100% pure Java application designed to load test functional behavior and measure performance. It was originally designed for testing Web Applications but has since expanded to other test functions. Apache JMeter™ may be used to test performance both on static and dynamic resources (files, Servlets, Perl scripts, Java Objects, Data Bases and Queries, FTP Servers and more). It can be used to simulate a heavy load on a server, network or object to test its strength or to analyze overall performance under different load types. Moreover, it can be used it to make a graphical analysis of performance or to test your server/script/object behavior under heavy concurrent load.

10. Conclusions
10.1. Under the load generated by 10 virtual users, ranging from 10 to 40 FPS, the following happened … 10.2. The test duration range was approximately from 20 minutes per test case to EXAMPLE minutes. 10.3. The EXAMPLE parameter was not found to have a significant impact on the server response time inside the tested range but it did have a strong positive influence on the percentage of frames that arrived later than required (note the %err parameter on the result tables). 10.4. Test cases where all 10 users view EXAMPLE produced approximately the same results as test cases where each user views a different EXAMPLE. 10.5. The maximum response times of GET pages (EXAMPLE) operations have been found to be significantly larger than the average (and even the 90%) values of those operations. That finding suggests that the slowest 10% might suffer EXAMPLE Playing discontinuities. 10.6. The maximum server response time measured was EXAMPLE seconds (Test case 221, FPS=40, where all 10 users EXAMPLE, total 10 users, EXAMPLE = EXAMPLE).
