10Mbit Ethernet

Manchester encoding effectively puts 2 bits in each 100nS bit position so the actual bit rate is 20Mbit
1.25 MByte per second, = 0.8uS per byte

A basic UDP Ethernet Packet:
8 byte ethernet startup sequence
14 byte MAC header
# btyes of data
4 bytes of frame check sequence
This means for the minimum packet size of 64 bytes + the 8 startup bytes, a theoretical max of 17361 packets per second are possible (1 UDP packet every 57uS).
