No, with these values the relay will push up to 2MBytes in each direction
each second. When the Burst is the same as the Rate, it's essentially
just like you're using the Rate. It doesn't add them.

My guess is that the original poster is confused because they wrote
"KBytes" in their torrc, but arm defaults to bits.
