AB instruction rate

I am looking for the AB document that gives the instruction rates for Control logix and compact logix processors.
I have downloaded it before, but now cannot find it...

Thanks,

In my "Program Files\Rockwell Software\RSLogix 5000\Common\ENU\Docs" directory, I have a pdf called "execution_time_and_memory.pdf".

It is Rockwell Publication: 1756-RM087E-EN-E, is that what you are looking for?

thanks
