First, let me make it clear that I know little PHP but I know a lot of
libcurl.

Using curl_multi_perform, it's no problem using up to at least hundreds of
transfers. If you go beyond hundreds, I recommend using curl_multi_socket(),
but I don't think the PHP binding supports that.

That's up to you to answer.

curl_multi does not increase transfer speeds, it just makes it easier to
transfer many things simultanouesly.

Sure if you find code that is written in a way that can be improved.

I don't understand the question.

I think your problems are related to how PHP and/or PHP/CURL works and aren't
strictly limitations of libcurl's multi interface.

And I have no idea what libcurl version that is bundled with PHP 5.2 so
possibly you could upgrade to a newer libcurl.
