This is because libcurl will try to fulfill your instructions as fast as
possible so it'll kick off all the 64 ones at once.
If the server supports HTTP/2, setting CURLOPT_PIPEWAIT for these transfers
*could* make them all get done over the same single connection.
Or if each individual transfers is quick, you can "distribute" the start of
those transfers yourself over time and thus drastically reduce the maximum
number of parallel connections needed.
