Query mixture types

Three query mixes were defined to cover a wide range of workloads:

• M1 - in which all six query types are equally likely to be requested.
• M2 - in which one of the two simple queries(I and II) is chosen half the time;
• M3 - in which the two simple queries have a combined probability of 75

For each of the following three cases, graphs have been drawn to show performance comparison. In all the graphs,
x axis is the number of concurrent queries
y axis is the throughput of the system measured in queries per second
