Ask HN: How do you get data out of MailChimp?

I have been using batch requests, but they are atrociously slow. It's taking about 10 minutes to export 10 e-mails (1 kilobyte json file). I talked to MailChimp support and it appears to be designed this way. Their focus is on the asynchronous aspect and not so much on the performance aspect of a background job.
