Difference between LR & Performance Center

LoadRunner	Performance Center
Loadrunner is a industry standard enterprise level load testing tool.	Performance Center is a web enabled load testing tool.
Resource management (VuGen scripts, scenarios and results) is local to the person, who is using the loadrunner tool on his local machine	Resource management is centralized, since it is web enabled.
If there are multiple performance test engineers using the shared lab, there is lot of dilemma how to reserve the lab for a specific load test.	Using performance center the lab machines can be reserved for a time slot.
Using load runner optimum usage of virtual users licenses is a problem, if more than one load tester is involved.	Virtual users can be reserved based on the time slot. So the user licenses can be optimally used in this case.
A single load test at a time can be initiated from a loadrunner controller.	Multiple load tests can be executed simultaneously using performance center.
Versioning of the resources is not possible.	Version of the resources is possible through performance center.
Locally accessible platform.	A Web-based, 24x7, globally accessible platform.
Assets can be shared only on the local projects.	Load test assets (VuGen scripts, results) can be shared across the project.
Monitoring will help identify infrastructure issues.	Infrastructure topology definition and monitoring to help identify infrastructure issues.
There is no traceability in loadrunner.	Performance requirements and defect traceability.
There is no direct integration with HP Application Lifecycle Management and Business Availability Center.	Integration with HP Application Lifecycle Management and Business Availability Center.
Loadrunner is good, if you have a small load testing team sitting in one location.	Performance center is good, if you have a large distrbuted load testing team sitting in different locations.
