Graph Analysis

At the bottom of the graph, there are the following statistics, represented in colors:

• Black: The total number of current samples sent.
• Blue: The current average of all samples sent.
• Red: The current standard deviation.
• Green: Throughput rate that represents the number of requests per minute the server handled

The Throughput is the most important parameter. It represents the ability of the server to handle heavy load. The higher the Throughput is, the better is the server performance.

The deviation is shown in red - it indicates the deviation from the average. The smaller the better.
