+Throughput Speedup Analysis - Multi-Core Speedup Ratio
+''''''''''''''''''''''''''''''''''''''''''''''''''''''
+
+Throughput Speedup Analysis (TSA) calculates a speedup factor for 1, 2, 4 cores
+which is defined as:
+
+::
+
+ throughput
+ speedup factor = -----------------
+ 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.
+
+For better comparision, there can be displayed more than one set of data in a
+plot. So, in general:
+
+ - 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.
+
+:TODO: Specify the data model for TSA.
