data model like this: {gen_id: 1234, other: data}the data is stored on 5 shards, the gen_id is the shard key,and is not unique. the problem is i found that if i send exactly the SAME query many times, the first query is always slow. the pageFaultExceptionsThrown and accessesNotInMemory counter didn't change, so it's not likely because of page faults. can anyone suggest and help me? Or dose the mongos need warm-up? |
