Try displaying deltaTime on the screen, and measure the difference in milliseconds. If you compare drawing 1000 particles to not drawing anything at all, then it should be much slower. Even something that is very fast is infinitely slower than something that takes zero time. Drawing nothing is close to zero.
If you aim for 60 frames per second, that gives you a max deltaTime of ~16.5 milliseconds, so compare the time taken to draw 1000 particles to that, and see how many percent of the target time is spent.
