Indexing in new Beta 4

Indexing (3,500 docs) seems MUCH slower in the new beta 4 than previous versions. It used to take less than 10 minutes to index this clump of docs, indexing has been running for >25 minutes and it isn’t finished yet. Any ideas?

See respone to the ticket: What kind of documents are you indexing and could you create a sample using Apple’s Activity Monitor? Thanks!
