It is now about 20-40ms depending on the server etc. Most of the time is spent in reading the ini config and static container / dependency injection.\r\n\r\nI reckon the normal tracker mode got a bit slower as well but as a normal request takes maybe 50-200ms anyway the regression is probably not that much of a problem.\r\n\r\nI uploaded a profile here: https://blackfire.io/profiles/983424c0-aa7e-446c-823b-59955f48212f/graph\r\n\r\nIn this case a client decided to use the QueuedTracking as it was very important to have a very fast tracker response time but the performance regressed."},"comment":{"url":"https://api.github.com/repos/piwik/piwik/issues/comments/94592323","html_url":"https://github.com/piwik/piwik/issues/7718#issuecomment-94592323","issue_url":"https://api.github.com/repos/piwik/piwik/issues/7718","id":94592323,"user":{"login":"diosmosis","id":125140,"avatar_url":"https://avatars.githubusercontent.com/u/125140?v=3","gravatar_id":"","url":"https://api.github.com/users/diosmosis","html_url":"https://github.com/diosmosis","followers_url":"https://api.github.com/users/diosmosis/followers","following_url":"https://api.github.com/users/diosmosis/following{/other_user}","gists_url":"https://api.github.com/users/diosmosis/gists{/gist_id}","starred_url":"https://api.github.com/users/diosmosis/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/diosmosis/subscriptions","organizations_url":"https://api.github.com/users/diosmosis/orgs","repos_url":"https://api.github.com/users/diosmosis/repos","events_url":"https://api.github.com/users/diosmosis/events{/privacy}","received_events_url":"https://api.github.com/users/diosmosis/received_events","type":"User","site_admin":false},"created_at":"2015-04-20T23:33:07Z","updated_at":"2015-04-20T23:33:07Z","body":"Right, but w/o an accurate profile, how will we diagnose + test the issue?
