I know there a couple of posts about this, and there seems to be no simple way for the user to check the performance (And there should be...). But it's simple for other software, you can run Cinebench, Geekbench, or simply do time comparisons in render time. It's a bit harder with Illustrator because it's static. So mostly we're measuring how long it took to navigate around the screen. And I don't know if it was slow because it's taking a long time, reading, writing or rendering.
To explain better:
I need to upgrade 15 computers, so it would be nice to have something to compare the current situation, where is the bottle neck or perfomance issues: cpu, gpu, ram, drive speed?
Does anyone have some sort of routine, maybe scripts or actions or a way they check it.
