10.5. Scalability Experiments

The goal of every cluster architecture is to achieve close to a linear performance scale-up when system resources are increased. However, achieving this goal in a real-world implementation is very challenging. In this section we present the results of two sets of experiments. First, we compared a single node server with two different network interface transmission speeds: 100 Mbps versus 1 Gbps. In the second set of experiments we scaled a server cluster from 1 to 2 to 4 nodes. We start by describing our measurement methodology. Table 10.2 lists all the terms used in this section.
