Code inspection, and profiling with the VS profiler, revealed that it's primarily the call tree under CheckInputSignature - stat64() calls for most files, plus some file hashing. By adding a profiler scope to CheckInputSignature, we account for most of the unaccounted-for time.","created_at":"2018-09-10T16:04:56Z","updated_at":"2018-09-10T16:04:56Z","closed_at":null,"merged_at":null,"merge_commit_sha":null,"assignee":null,"assignees":[],"requested_reviewers":[],"requested_teams":[],"labels":[],"milestone":null,"commits_url":"https://api.github.com/repos/Unity-Technologies/tundra/pulls/29/commits","review_comments_url":"https://api.github.com/repos/Unity-Technologies/tundra/pulls/29/comments","review_comment_url":"https://api.github.com/repos/Unity-Technologies/tundra/pulls/comments{/number}","comments_url":"https://api.github.com/repos/Unity-Technologies/tundra/issues/29/comments","statuses_url":"https://api.github.com/repos/Unity-Technologies/tundra/statuses/8ab2f8d8d2d698b9cdacd21353d69d6630ce3425","head":{"label":"Unity-Technologies:feature/profile_build_loop","ref":"feature/profile_build_loop","sha":"8ab2f8d8d2d698b9cdacd21353d69d6630ce3425","user":{"login":"Unity-Technologies","id":426196,"node_id":"MDEyOk9yZ2FuaXphdGlvbjQyNjE5Ng==","avatar_url":"https://avatars0.githubusercontent.com/u/426196?v=4","gravatar_id":"","url":"https://api.github.com/users/Unity-Technologies","html_url":"https://github.com/Unity-Technologies","followers_url":"https://api.github.com/users/Unity-Technologies/followers","following_url":"https://api.github.com/users/Unity-Technologies/following{/other_user}","gists_url":"https://api.github.com/users/Unity-Technologies/gists{/gist_id}","starred_url":"https://api.github.com/users/Unity-Technologies/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Unity-Technologies/subscriptions","organizations_url":"https://api.github.com/users/Unity-Technologies/orgs","repos_url":"https://api.github.com/users/Unity-Technologies/repos","events_url":"https://api.github.com/users/Unity-Technologies/events{/privacy}","received_events_url":"https://api.github.com/users/Unity-Technologies/received_events","type":"Organization","site_admin":false},"repo":{"id":115012341,"node_id":"MDEwOlJlcG9zaXRvcnkxMTUwMTIzNDE=","name":"tundra","full_name":"Unity-Technologies/tundra","owner":{"login":"Unity-Technologies","id":426196,"node_id":"MDEyOk9yZ2FuaXphdGlvbjQyNjE5Ng==","avatar_url":"https://avatars0.githubusercontent.com/u/426196?v=4","gravatar_id":"","url":"https://api.github.com/users/Unity-Technologies","html_url":"https://github.com/Unity-Technologies","followers_url":"https://api.github.com/users/Unity-Technologies/followers","following_url":"https://api.github.com/users/Unity-Technologies/following{/other_user}","gists_url":"https://api.github.com/users/Unity-Technologies/gists{/gist_id}","starred_url":"https://api.github.com/users/Unity-Technologies/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Unity-Technologies/subscriptions","organizations_url":"https://api.github.com/users/Unity-Technologies/orgs","repos_url":"https://api.github.com/users/Unity-Technologies/repos","events_url":"https://api.github.com/users/Unity-Technologies/events{/privacy}","received_events_url":"https://api.github.com/users/Unity-Technologies/received_events","type":"Organization","site_admin":false},"private":false,"html_url":"https://github.com/Unity-Technologies/tundra","description":"Tundra
