I haven't done measurements, but the first query with a sort on a particular field will involve filling the field-cache and that can take a while (especially for numeric fields). If you haven't already, you should compare the query times of a "warmed" searcher. Sorted queries will still take long

High CPU utilization with sort

2005-11-20 Thread Jeff Rodenburg
I've read many comments from users on the list indicating that sorting may/will be performance-heavy. Is high CPU utilization with a sorted search one of the expected performance hits? In tests for our implementation (25 concurrent connections generating search/sort requests), we've seen performan
