-Throughput Speedup Analysis (TSA) calculates a speedup factor for 1, 2, 4 cores

+Throughput Speedup Analysis (TSA) calculates throughput speedup ratios
+for tested 1-, 2- and 4-core multi-threaded VPP configurations using the
+following formula:
::
- throughput
- speedup factor = -----------------
- 1-core-throughput
+ N_core_throughput
+ N_core_throughput_speedup = -----------------
+ 1_core_throughput
-A bar plot displays the speedup factor (normalized throughput for 64B/78B on 1
-core). The plot displays number of cores on the X-axis and the speedup factor on
-the Y-axis.
+Multi-core throughput speedup ratios are plotted in grouped bar graphs
+for throughput tests with 64B/78B frame size, with number of cores on
+X-axis and speedup ratio on Y-axis.
-For better comparision, there can be displayed more than one set of data in a
-plot. So, in general:
+For better comparison multiple test results' data sets are plotted per
+each graph:
- graph type: grouped bars;
- graph X-axis: (testcase index, number of cores);
- graph Y-axis: speedup factor.
-The data displayed is a subset of existing performance tests with 1core, 2core,
-4core.
+Subset of existing performance tests is covered by TSA graphs.

Advanced data analytics

-As the next steps, advanced data analytics (ADA) will be implemented using
-machine learning (ML) and artificial intelligence (AI).
+In the future advanced data analytics (ADA) will be added to analyze the
+telemetry data collected from SUT telemetry sources and correlate it to
