Consider the following\r\n\r\n* Play framework has 3 repos by default\r\n* In Australia, ping times times to maven/typesafe repos are 200ms (at least)\r\n* If an artifact is not found in any repo (for example, when looking up source artifacts), that could total up to 6 round trips, or 1.2 seconds, just to ascertain that an artifact can't be found.\r\n* Running play eclipsify from scratch, I can count on it taking about 10 minutes just to download everything, even with a 20mb/s internet connection, it's the round trip times that kill me.\r\n\r\nDownloading in parallel would go a long way to help mitigate this.  Checking repositories for artifacts in parallel would help even more."},"comment":{"url":"https://api.github.com/repos/sbt/sbt/issues/comments/105394933","html_url":"https://github.com/sbt/sbt/issues/590#issuecomment-105394933","issue_url":"https://api.github.com/repos/sbt/sbt/issues/590","id":105394933,"user":{"login":"eed3si9n","id":184683,"avatar_url":"https://avatars.githubusercontent.com/u/184683?v=3","gravatar_id":"","url":"https://api.github.com/users/eed3si9n","html_url":"https://github.com/eed3si9n","followers_url":"https://api.github.com/users/eed3si9n/followers","following_url":"https://api.github.com/users/eed3si9n/following{/other_user}","gists_url":"https://api.github.com/users/eed3si9n/gists{/gist_id}","starred_url":"https://api.github.com/users/eed3si9n/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/eed3si9n/subscriptions","organizations_url":"https://api.github.com/users/eed3si9n/orgs","repos_url":"https://api.github.com/users/eed3si9n/repos","events_url":"https://api.github.com/users/eed3si9n/events{/privacy}","received_events_url":"https://api.github.com/users/eed3si9n/received_events","type":"User","site_admin":false},"created_at":"2015-05-26T04:59:13Z","updated_at":"2015-05-26T04:59:13Z","body":"https://github.com/sbt/sbt/tree/wip/ivy-parallel-artifact-download"}}
