I have a query that runs fast enough in if I'm just viewing it. It's returning about 29K records. in 20-30 seconds. I can view any record, etc. Tables have indexes. My problem is when I try to output it using transfer spreadsheet or make the query an append query it's taking 30+ minutes to run. I haven't had this problem before. I've done more complex queries and they haven't given me this trouble. Could bitlocker be causing this problem?
