15K against local lighttpd with an ancient home Pentium-4 3.0 GHz and
1GB of a slow
unchecked memory with a fine tuning of some kernel params as here:
http://curl-loader.sourceforge.net/doc/faq.html#big-load

The main issues to reach 50-100 K may be a strong CPU consumption
by CreateConnection (still to investigate - could be a memory allocation
issue), enough memory - 4-8 GB of a fast checked memory on a good bus
with a good dual CPU server, like Supermicro or Tyan AMD Opteron.

A server side able to run 50-100 K connections may be lighttpd (epoll mode
with fd-max increased) with another piece of a good HW, where a single CPU
server with 2GB memory might be enough.
