how to verify SGX usage

Hi,

I just built a graphical application but performance are not
satisfying.
I would like to verify that I am really using the hardware
acceleration, and not software rendering.

I am using ubuntu 2.6.29-oer44.1 using SGX driver 09.

Is there any way to verify the usage of the HW acceleration using the
command line (or any other way)?

Thanks,
