Rani,

I hope both the testing is a blockboix oriented. The thing is System testing is a combination of Functional and Non-Fucntional Testing. whereas in Functional testing, we will test only the functionality.

From the requirement (He may wants the profile creation should be done in 10 secs. here we have both function(adding profile)  and non-function(10 secs) . so testing the both is called system testing.
