I'm not aware of any, but I too would love to see some numbers...

In my work with the curl_multi_socket() API I did some evaluations on how it
performs compared to curl_multi_perform(). In extreme cases, like when there
are 10000 idle connections and one active, the curl_multi_socket() can be up
to 1500 times faster. Of course a real-world test case is not that simple and
even though it should still be faster, I bet the difference will be more
moderate.
