I design socket component suites for developers, on windows, with few
registry tweaks, you are able to have over 50,000 live, hot sockets. On
Linux 2.6 and later, I have yet to hit a serious limit.

Performance wise, your focus will be poor memory paging, so make sure
you have too much RAM, and nothing else running.
