How often the documents are added in the index? Try lessen down the optimize frequency. BTW do you optimize only on master (which should be the desired way).
Also specifically for dates ranges, try to use the filter queries, this way it would be cached and would thus be faster. This would also apply to other fields which require very less analysis or have limited unique fields.
