Thanks! Which index should I put on modifyTimestamp?

We have an application that needs to query for and return thousands of entries with modifyTimeStamp greater than a given time. This is turning out to be too slow for this app and so I'm wondering if there's any way to speed this up other than throwing more CPU at it.

Is modifyTimestamp indexed?

Have you raised your idlscanlistlimit to 999999999? 

Sounds like you have a full table scan going on. The above two changes will fix it.
