Hi, I am using elasticsearch 1.7. I have daily indexes when I do a search with scroll, with tree months de elasticsearch became too slow or not responsive. Take a look some graphs that I printed from Marvel from data nodes 3 Master Java Heap: 5GB 2 CPUs, Intel(R) Xeon(R) CPU E5-2670 v2 @ 2.50GHz RAM:7,5GB 3 data nodes Java Heap: 8GB 2 CPUS : Intel(R) Xeon(R) CPU E5-2670 v2 @ 2.50GHz RAM: 15GB 2 client nodes Java Heap: 5GB 2 CPUs Intel(R) Xeon(R) CPU E5-2670 v2 @ 2.50GHz RAM: 7,4GB ![](https://us1.discourse-cdn.com/elastic/original/2X/1/18377f43dd1c0438a2880910acabcb2c640e097b.png) ![](https://us1.discourse-cdn.com/elastic/original/2X/9/96f1bacfc4fea5fe3050ac22b33e93b71e15752a.png) ![](https://us1.discourse-cdn.com/elastic/original/2X/8/86011384a5ac7983240648f96777ec8b871fa73e.png) ![](https://us1.discourse-cdn.com/elastic/original/2X/0/023dd1d89a787bb03b38fafa5182f4eb59b8ef6c.png) ![](https://us1.discourse-cdn.com/elastic/original/2X/c/caedc0d7d808c4a77691cd3ad8454df96a9ccbda.png) ![](https://us1.discourse-cdn.com/elastic/original/2X/4/46b460f6350d6d92f904249e6dc125c7b2fa3793.png) ![](https://us1.discourse-cdn.com/elastic/original/2X/4/4d1dee48670ffacdf8a5c849f74ae088723d83d2.png) What is the best approach, increase number of machines? Increase the machines sizes? change architecture of my solution? My search `{ "_source": { "exclude": ["entries.*.request.postData", "entries.*.response.content"] }, "query": { "bool": { "must": [{ "term": { "_entrypoint.id": 5 } }, { "term": { "_api.version.id": 1 } }, { "query_string": { "query": "1111111" } }, { "range": { "entries.entrypoint.startedDateTime": { "gt": "2016-06-01T03:00:00.000Z", "lte": "2016-06-09T13:05:00.000Z" } } }] } }, "sort": [{ "entries.entrypoint.startedDateTime": { "order": "desc" } }] }` ---
