Need to know about Performance testing tool which can test VB 6, ASP.NET and C# toget

Hi All,

I have got an application which is integration of 3 sub applications, 1st sub application is developed in ASP.NET, the 2nd in VB 6.0 and 3rd in C#. These 3 sub application is combined and integrated to one and have dependencies on each other.

I need to execute Performance Testing in this application which should cover up the performance testing for all the 3 sub applications and produce a result which displays the overall report of the performance of the entire application.

I need to know the following things....

Performance testing tool which can test all the 3 sub applications in VB, ASP.NET and C# together

OR

Performance testing tool which test the 3 sub application seperately and then integrate the results into one

OR

Performance testing tool which tests VB, testing tool for ASP.NET and testing tool for C# (In this case I will have to find out another way to combine the results into one manually)

Please suggest me which Performance Testing Tool I can use to satisfy either of 3 conditions mentioned above.....Please respond to my queries ASAP as I have a thin deadline to complete this task.
