Troubleshooting to get performance related information

Is there any provision in Aveva applications ( E3d, diagrams & engineering ) to start the application in such a way that it can log performance related information?

Or troubleshooting logs ? 

I want to find which things in the environment causing delays in application startup?

I have lots of dlls iaddins & lots of pml stuff... 

Decoupling each and check startup takes lot of time, so is there any way to check troubleshooting info or timing for loading each things in aveva ?

Thanks in advance...
