In this set of videos Jaqui discusses ways to avoid causing performance problems (and other problems) in the first place and will then go into the steps that should be followed to determine whether it really is a performance problem and how to then go ahead and get help to resolve it. This session will also touch on some of the new performance tools available to assist with this.
