2. The C10K problem (http://www.kegel.com/c10k.html)
“It's time for web servers to handle ten thousand clients simultaneously,
don't you think? After all, the web is a big place now.”
“In 1999 one of the busiest ftp sites, cdrom.com, actually handled 10000
clients simultaneously through a Gigabit Ethernet pipe.”
Possible solutions:

Non-Blocking

Blocking (one thread per client)

Asynchronous
