  • To address this issue , performance testing is carried out to check  & fine tune system response times. The goal of performance testing is to reduce response time to an acceptable level
  • Or you may have seen messages like - (pic in video ) .Hence load testing is carried out to check systems performance at different loads i.e. number of users accessing the system
  • Depending on the results and expected usage, more system resources may be added
