WAPT is able to generate up to 3000 simultaneously acting virtual users using standard hardware configuration. Virtual users in each profile are fully customizable. Basic and NTLM authentication methods are supported. Graphs and reports are shown in real-time at different levels of detail, thus helping to manage the testing process.
