[07:59:41] <izhak> Hi, guys! I have a 15M rows collection which I scan using regex (there is an index on the regex filtered field). When I get more then 8M rows, my client just hangs. On server I can see that disk reads become very low suddenly (from 50M to 2M per second). This happens when actual free memory becomes less then 80M. How do I get all that records out of mongo?
