Ntuplizing 10k MC events take 200 seconds vs 20 seconds from my latest PR around mid-February, when I was on 2.3.38. The snapshot is here: https://github.com/urania277/xAODAnaHelpers\r\n\r\nAdmittedly, I haven't really followed everything too closely, but I didn't think anything major would have changed to my private tree-dumping code downstream except for this systematic change. \r\n\r\nHas anyone else noticed this / am I doing something wrong / do you have any ideas on where to start looking for reasons for this speed-down?\r\n\r\nThanks,\r\nCaterina"},"comment":{"url":"https://api.github.com/repos/UCATLAS/xAODAnaHelpers/issues/comments/208647646","html_url":"https://github.com/UCATLAS/xAODAnaHelpers/issues/572#issuecomment-208647646","issue_url":"https://api.github.com/repos/UCATLAS/xAODAnaHelpers/issues/572","id":208647646,"user":{"login":"urania277","id":8102713,"avatar_url":"https://avatars.githubusercontent.com/u/8102713?v=3","gravatar_id":"","url":"https://api.github.com/users/urania277","html_url":"https://github.com/urania277","followers_url":"https://api.github.com/users/urania277/followers","following_url":"https://api.github.com/users/urania277/following{/other_user}","gists_url":"https://api.github.com/users/urania277/gists{/gist_id}","starred_url":"https://api.github.com/users/urania277/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/urania277/subscriptions","organizations_url":"https://api.github.com/users/urania277/orgs","repos_url":"https://api.github.com/users/urania277/repos","events_url":"https://api.github.com/users/urania277/events{/privacy}","received_events_url":"https://api.github.com/users/urania277/received_events","type":"User","site_admin":false},"created_at":"2016-04-12T00:46:35Z","updated_at":"2016-04-12T00:46:35Z","body":"No change in time for me there (ran on the same file, .38 vs .45).
