Difference between Loadrunner and 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
