I am new to oprofile and I have a couple of questions.

1) Can oprofile be used to find out the performance of
    a program that runs via an interpreter?  The interpreter
    I am using is R.

2) Assuming YES to the above question, I am using Redhat
    linux and I don't have vmlinux. Instead, I have vmlinuz.
    Does this mean I can do:

    opcontrol --vmlinux=/boot/vmlinuz-`uname -r`

    Or does it mean I must do:

    opcontrol --no-vmlinux

Thank you in advance.
