That said, you should also consider the signalling and framing that Ethernet adds. Each new Ethernet transmission requires 8 bytes preamble + 18 bytes framing + 12 bytes waiting time + potential waiting time due to collisions. That means, that you can send at least another 8 + 18 + 12 + 18 = 56 bytes of data in your first frame without it actually being more expensive than splitting it up into two minimum-sized ethernet frames. So, 74 bytes of UDP payload in one ethernet frame is as expensive as two frames carrying 18 bytes each.
I must correct myself here. Forgot the IP and UDP headers in that second frame. Add another 28 bytes, replacing 74 with 102 in the reasoning above...
