I don't think we fixed any major performance wise flaws since then, at least
not for the regular curl_multi_perform() case. Of course you should probably
make sure your libcurl is built with c-ares to get the transfers done slightly
nicer as then you overcome the name resolving phase the best possible way (in
my view of course).

In the code, by writing test applications or by discussing it with fellow
libcurl hackers on the curl-library mailing list.

Do note that I here speak of libcurl as in the actual library doing the
transfers. curl is the command line tool, PHP/CURL is the PHP binding for
libcurl.

There are many users who use libcurl to do several hundreds (and even
thousands) of simultanoues transfers.
