Few days ago we were told by the pilot users of our BA Server that for few minutes their performance when creating reports drastically dropped. Our initial guess was that probably it was somehow related to one of the ETL processes running in the background. We started monitoring the database, but we did not see nothing interesting. Hence we decided to get deeper insight into the performance of the BA server itself. My colleague decided to use JMeter but me, I wanted to see whether Selenium engine can get me somewhere.
