I have a code that takes 6min to run on Linux and Windows 10. This same code takes 97min on Windows 8.\r\n\r\nI investigated other possible causes by running the code with different Julia releases on different computers. There are only two possible causes left: Windows 8 weirdness or HD vs. SSD. The latest cause is unlikely given that my package is not doing any explicit access to the disk."},"comment":{"url":"https://api.github.com/repos/JuliaLang/julia/issues/comments/221926005","html_url":"https://github.com/JuliaLang/julia/issues/16570#issuecomment-221926005","issue_url":"https://api.github.com/repos/JuliaLang/julia/issues/16570","id":221926005,"user":{"login":"KristofferC","id":1282691,"avatar_url":"https://avatars.githubusercontent.com/u/1282691?v=3","gravatar_id":"","url":"https://api.github.com/users/KristofferC","html_url":"https://github.com/KristofferC","followers_url":"https://api.github.com/users/KristofferC/followers","following_url":"https://api.github.com/users/KristofferC/following{/other_user}","gists_url":"https://api.github.com/users/KristofferC/gists{/gist_id}","starred_url":"https://api.github.com/users/KristofferC/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/KristofferC/subscriptions","organizations_url":"https://api.github.com/users/KristofferC/orgs","repos_url":"https://api.github.com/users/KristofferC/repos","events_url":"https://api.github.com/users/KristofferC/events{/privacy}","received_events_url":"https://api.github.com/users/KristofferC/received_events","type":"User","site_admin":false},"created_at":"2016-05-26T16:38:55Z","updated_at":"2016-05-26T16:38:55Z","body":"@juliohm AntiViruses can definitely mess with performance since they hook into a bunch of calls. Especially if you are opening and closing many files. I'm not sure if your application is doing that but if the only common factor is the software the IT people fill the computer with then it  is worth looking into."}}
