Once the need to use a tool to simulate concurrent users
becomes apparent, we have to choose the right tool to simulate
a real LMS usage. A number of tools are available for our
purposes, among others, Apache JMeter [10], ab – Apache
HTTP Server Benchmarking Tool [11], Badboy [12], HP
LoadRunner [13], IBM Rational Performance Tester [14],
Selenium IDE [15], or Silk Performer [16]. We have analyzed
these tools and chosen one of them to conduct the experiments
of this work.
