With my 6502 port of uIP running with a CS8900a chip (look at 
http://dunkels.com/adam/tfe/), a ping flood resulted in 7/8 packets being 
dropped which isn't that bad considering that the CPU runs at 1MHz and that 
the CS8900a only has 4k of buffer memory.

Because of the throughput limitations of uIP, it doesn't give throughput 
anyway near the 70 kilobytes per second you have, but with a stateless 
TCP-optimization trick it was able to serve over 10000 web pages per hour to 
over 50000 visitors during one busy day. The server is still up at 
http://tfe.c64.org/.
