While I don't have any actual numbers, I'm pretty sure you won't be
getting a guard flag with that kind of speed. Actually, I don't think
you'll get much traffic at all with that slow of a relay, especially
since the recommended upload speed is 2Mbps (1600kBytes/s).
No, 2Mbps are 250KBps, 2 Megabit = 250 Kilobyte (as 8 Megabit are 1
Megabyte).
Recommended minimum upload speed to run a relay is 100Kilobyte/s, so
1Mbps is already enough to run a relay. [1]
To be a relay, your bandwidth has to be at least 250KB/s. [2]
