In this post, we shall cover the basic knowledge of using Quick Test Professional (QTP) for load testing with LoadRunner. Unlike conventional protocols in LoadRunner where you record in Vugen, modify, port into Controller and run the execute button, you will need to do a few more stuff in order to get the setup right and running. This knowledge will aid you in planning, budgeting, finding resources and minimizing any hiccups when setting up for such load test. Read the rest of this entry »

Seldom, we discuss about the planning and implementation of the load test in our site. As such, we are taking a change in this and will be touching on some considerations you as a performance tester/test manager/consultant should be thinking for every load test. These considerations enable you to smooth up the process of the entire load test and reduce any load test risks associated with it. More than often, we focus on gathering the customers requirements for the load test such as user amount to generate, how long the load test will be conducted, where will it be conducted, the location that the virtual users will generate from, etc… That is basic information. However, additional information will be required to smoothen the load test project and below are some of the additional considerations, you as a performance tester/test manager/consultant should be asking yourself or client.

After the tune-able parameters are changed for optimal performance, your system still fails miserably with a poor response time. The most likely step you should take is to do a deep diagnostics on the system. Break the system up into different components such as application server where diagnostics using probes is required, database servers where SQL statements and stored procedures become the next to be scrutinized, etc… Read the rest of this entry »

High performance web sites and applications can start from the design coding level. Most of the time, performance tuning we view comes at the later stage of the development life cycle, in particular at the deployment stage. What can we do by deployment stage? We can only tune start up parameters, add more hardware, or add more network components in the architecture. But what if the problem is in the JVM where you diagnose it to be poor application performance due to coding? Changing codes at this stage will be more expensive and difficult unlike when you are in the development stage! Read the rest of this entry »
