I made lot of tests, changing for oracle JVM, changing for G1GC, but nothing worked.\r\n\r\nSi i begun to check the hot threads API and saw percolator were using large amount of CPU.\r\n\r\nJust desactivated the percolator query (with 4 percolator query in index), and here is the result : \r\n![screenshot012](https://cloud.githubusercontent.com/assets/1506320/5780568/d95b1d60-9dab-11e4-9f9e-9b8efbe0a248.png)\r\n\r\nSince i desactivated client.percolate in node.js code, CPU are low used.\r\n\r\nDoes anyone know why percolator query is killing GC performances ?\r\n\r\nThanks a lot for your help !\r\n"},"comment":{"url":"https://api.github.com/repos/elasticsearch/elasticsearch/issues/comments/72203191","html_url":"https://github.com/elasticsearch/elasticsearch/issues/9337#issuecomment-72203191","issue_url":"https://api.github.com/repos/elasticsearch/elasticsearch/issues/9337","id":72203191,"user":{"login":"martijnvg","id":580421,"avatar_url":"https://avatars.githubusercontent.com/u/580421?v=3","gravatar_id":"","url":"https://api.github.com/users/martijnvg","html_url":"https://github.com/martijnvg","followers_url":"https://api.github.com/users/martijnvg/followers","following_url":"https://api.github.com/users/martijnvg/following{/other_user}","gists_url":"https://api.github.com/users/martijnvg/gists{/gist_id}","starred_url":"https://api.github.com/users/martijnvg/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/martijnvg/subscriptions","organizations_url":"https://api.github.com/users/martijnvg/orgs","repos_url":"https://api.github.com/users/martijnvg/repos","events_url":"https://api.github.com/users/martijnvg/events{/privacy}","received_events_url":"https://api.github.com/users/martijnvg/received_events","type":"User","site_admin":false},"created_at":"2015-01-30T13:52:16Z","updated_at":"2015-01-30T13:52:16Z","body":"@kaliseo Are you percolating documents that have a nested mapping?
