When I repeat the same search over and over again I get somewhat wild fluctuations in run time: 4ms, 4ms, 87ms, 17ms, 157ms, 4ms, 4ms, 4ms
Any ideas what might cause this? This only seems to happen on my production cluster so I'm not likely to be able to make full reproduction steps. I causing it with a simple match query without any filters or anything. Normally I trace performance stuff by causing lots of traffic and looking at hot_threads but that these fluctuations don't feel like they'd be easy to catch that way. I have 16 nodes on real hardware with somewhat slow disks and 30GB heaps with 96GB total ram. We write to the indexes constantly but slowly. Maybe 2-3 updates (not new docs, changes to old docs) per second per shard. Any ideas would be great, Thanks Nik -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
