Hi there! How is it going? Sometimes, when we talk about device performance we are talking in terms of packets per second (pps) and bits per second (bps). But in latter case it's not quite correct to say "this device can do one hundred megabits ber second" because router/switch/whatever performance is greatly depends on packet size and if you want to mention device performance in a more accurate and professional way you would say "this device can do one hundred megabits per second at 64 bytes packet size"
