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.

TCP Delayed ACKs	Number of resend buffers * (10 + transmit buffer size)

Without IP Fragmentation: add user selected buffer sizes + 68 bytes per socket

With IP Fragmentation: add user selected buffer sizes + 36 bytes + 88 bytes per socket + size of reassembly buffer(s)

Ethernet throughput numbers are calculated by timing the transmission of 60000 UDP packets containing 1470 bytes of data with Iperf.
