Question

(a) The throughputs of two systems A and B were measured in query per second. The results are shown in the Table below. Compare the performance of the two systems and show that (1) System A is better (ii) System B is better (iii) the two systems are equally, good 19 marks]

Throughput in Queries per Second System

10 30

Answer 1

To compare the performance of systems A and B based on the provided throughput data for Workload 1 and Workload 2, you can calculate some key metrics and make comparisons.

First, let's calculate the average throughput for each system:

**System A:**
- For Workload 1: (30 + 10) / 2 = 20 queries per second
- For Workload 2: (10 + 30) / 2 = 20 queries per second

**System B:**
- For Workload 1: (10 + 30) / 2 = 20 queries per second
- For Workload 2: (30 + 10) / 2 = 20 queries per second

Now, we can see that both System A and System B have the same average throughput for both workloads, which is 20 queries per second. Therefore, based on the average throughput alone, you can conclude that:

(iii) The two systems are equally good in terms of throughput for the given workloads.

There is no significant difference in performance between System A and System B based on the provided data.
