Could this be because the multi interface gets a large amount of handles and
sockets to loop around between?

Have you tried excluding https:// URLs and see if that makes anything
different? (SSL connections are still partly synchronous within libcurl.)

The vast amount of simultanoes URLs makes it really tricky to debug this. Can
you detect slowdowns already when using very few URLs, like 3 or 4?
