Quality center & Performance center in Load runner.

Hi, guys i want to know the different between [B]Quality center[/B] and [B]Performance center[/B] in Load runner.

As far i read the help file i found that, both are doing same work by creating vugen script , storing it and opening script and editing the script and once again placing it either in desired place.

PerformanceCenter is a superset of LoadRunner and uses all of the LoadRunner components as part of it's deployment architecture. For details you should contact HP or your HP VAR.
