Web Performance Testing

Load & Performance

Today, when a telephone system is installed in a new neighborhood, it will always work perfectly. The phone will ring, the line will connect immediately, and people can communicate with each other even if all the neighbors are speaking at the same time. This is because over time and due to algorithms which have been developed, it is known how much hardware is needed to support a specific area. Web technology is very different. There can be a different number of servers, different amounts of resources per server, different and new technologies, many different parameters can be configured to improve performance and naturally code can always be improved.

Experience and Performance Testing

Experienced performance testers are a necessity to any testing venture: they will speak your language and guide you through the process of meeting your goals, even if you’re as yet unable to articulate what those goals are. They not only know how to relate to executives in terms of business risks, short- and long-term costs, and implications of schedule adjustment, but they also know how to explain their testing. It is the job of the performance tester to define the conditions under which the goal applies; i.e. to determine the goal's context. Therefore, this goal must address such things as client connection speed, number of people accessing the site, and the types of activities those people are performing.
