Okay, I did three runs using the list of IDs you provided (63.6 MB):

By no means definitive, but sufficient to give me no reason to change my mind that 2 threads per core will usually give the best throughput. You might consider lowering the number of threads you run and see if it doesn't improve your throughput also.

One aside: If you have contact with the webmaster, you might suggest that he return a non-200 return code for unfound id's instead of returning 200 and a file containing: "Can't find that type". He explicitly asks people to not continually request non-existant data. That goal would be far easier to achieve if he did his bit by returning meaningful status codes.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
"Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."
