However, when under heavy load, the QPS limit to the API server causes this round trip to take ~60 seconds, which is an unacceptable increase in latency. Take a look at the graphs in #40239 to see the effect of QPS changes on timing.\r\n- To remedy this, the volume manager looks at the status from the status manager, which eliminates the round trip.\r\n\r\ncc: @vishh @derekwaynecarr @sjenning @jingxu97 @kubernetes/sig-storage-misc "},"comment":{"url":"https://api.github.com/repos/kubernetes/kubernetes/issues/comments/278522380","html_url":"https://github.com/kubernetes/kubernetes/pull/41095#issuecomment-278522380","issue_url":"https://api.github.com/repos/kubernetes/kubernetes/issues/41095","id":278522380,"user":{"login":"ncdc","id":354,"avatar_url":"https://avatars.githubusercontent.com/u/354?v=3","gravatar_id":"","url":"https://api.github.com/users/ncdc","html_url":"https://github.com/ncdc","followers_url":"https://api.github.com/users/ncdc/followers","following_url":"https://api.github.com/users/ncdc/following{/other_user}","gists_url":"https://api.github.com/users/ncdc/gists{/gist_id}","starred_url":"https://api.github.com/users/ncdc/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ncdc/subscriptions","organizations_url":"https://api.github.com/users/ncdc/orgs","repos_url":"https://api.github.com/users/ncdc/repos","events_url":"https://api.github.com/users/ncdc/events{/privacy}","received_events_url":"https://api.github.com/users/ncdc/received_events","type":"User","site_admin":false},"created_at":"2017-02-09T01:49:47Z","updated_at":"2017-02-09T01:49:47Z","body":"Or is that what #41157 is trying to address?"}}
