Post Indexer speed for building index

Hello. Have Post Indexer running for about 24 hours now. It indexed 200 posts so far. Our posts are generally 600-1000 words in length. Is that a normal index speed or can I set it somewhere to go faster? I'd like to get through the first 1,000 posts in less than 24 hours, then it can revert back to a more casual speed.

Thank you.
