60K clients x 25K memory/client (our tuning of libcurl memory)
= 60 000 x 30 000 = 1, 6 GB user space + ~100 M
in kernel on a machine with 2 GB memory

It could be further optimized.

Sure, both linux.

Standard build on linux gives epoll handling as the default,
increased num of allowed clients to 64K
the directive for allowed descriptor (not not remember the exact
name something rlimit_nofile) increased up to 64K

ulimit -n 100000

some tuning from curl-loader page, see our FAQs on the web-site,
enjoy Israel flag.

Client side - sure , a single one, but maybe more memory, lets see.
Ixia is a single box.
