The numbers are for popular compilers. The actual sizes will vary according to the compiler and optimization used. Ethernet code sizes and RAM usage will vary depending upon the ethernet controller used, onboard or external.

Ethernet	90 plus a configurable size of buffers from 384 to 4608 bytes

Without IP Fragmentation: add user selected buffer sizes + 59 bytes per socket

With IP Fragmentation: add user selected buffer sizes + 32 bytes + 79 bytes per socket + size of reassembly buffer(s)

Ethernet throughput numbers are calculated by timing the transmission of 1000 UDP packets containing 1460 bytes of data.
