In certain cases, Applab loads in **less than half the time** with prerendered script tags vs. the original time using dynamic serial loading.\r\n\r\nMeasurements were taken in Chrome 45 with cache disabled.  Given times (measured in seconds) are the duration from the beginning of page load to the \"Load\" event firing as recorded by the Network tab of the developer console (which corresponds to initialization scripts finishing).  Each measurement represents the average of five trials.  Baselines were taken against production on studio.code.org.  Improved measurements were taken against profiling.code.org, an environment we set up to emulate production as closely as possible (a frontend behind a similar load balancer, using SSL, minified assets, etc.).\r\n\r\nPage | Network | Baseline | Improved | Difference\r\n-----|---------|----------|----------|-----------\r\nBlockly ([this level](https://studio.code.org/s/course2/stage/3/puzzle/2)) | 3G (1Mbps, 40ms RTT) | 7.68 | 6.17 | -19.64%\r\nApplab (new project) | 3G (1Mbps, 40ms RTT) | 10.05 | 7.70 | -23.35%\r\nApplab (new project) | Unthrottled | 7.31 | 3.30 | -54.83%\r\n\r\nI suspect the dramatic improvement for Applab on an unthrottled network connection is because it can really take advantage of the parallel loading change.\r\n","created_at":"2015-10-14T21:54:55Z","updated_at":"2015-10-14T21:54:56Z","closed_at":null,"merged_at":null,"merge_commit_sha":null,"assignee":null,"milestone":null,"commits_url":"https://api.github.com/repos/code-dot-org/code-dot-org/pulls/4571/commits","review_comments_url":"https://api.github.com/repos/code-dot-org/code-dot-org/pulls/4571/comments","review_comment_url":"https://api.github.com/repos/code-dot-org/code-dot-org/pulls/comments{/number}","comments_url":"https://api.github.com/repos/code-dot-org/code-dot-org/issues/4571/comments","statuses_url":"https://api.github.com/repos/code-dot-org/code-dot-org/statuses/10fb7ea3de640c6e916134039246dfbfbf30650f","head":{"label":"code-dot-org:applab-better-script-loading","ref":"applab-better-script-loading","sha":"10fb7ea3de640c6e916134039246dfbfbf30650f","user":{"login":"code-dot-org","id":5124627,"avatar_url":"https://avatars.githubusercontent.com/u/5124627?v=3","gravatar_id":"","url":"https://api.github.com/users/code-dot-org","html_url":"https://github.com/code-dot-org","followers_url":"https://api.github.com/users/code-dot-org/followers","following_url":"https://api.github.com/users/code-dot-org/following{/other_user}","gists_url":"https://api.github.com/users/code-dot-org/gists{/gist_id}","starred_url":"https://api.github.com/users/code-dot-org/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/code-dot-org/subscriptions","organizations_url":"https://api.github.com/users/code-dot-org/orgs","repos_url":"https://api.github.com/users/code-dot-org/repos","events_url":"https://api.github.com/users/code-dot-org/events{/privacy}","received_events_url":"https://api.github.com/users/code-dot-org/received_events","type":"Organization","site_admin":false},"repo":{"id":24250009,"name":"code-dot-org","full_name":"code-dot-org/code-dot-org","owner":{"login":"code-dot-org","id":5124627,"avatar_url":"https://avatars.githubusercontent.com/u/5124627?v=3","gravatar_id":"","url":"https://api.github.com/users/code-dot-org","html_url":"https://github.com/code-dot-org","followers_url":"https://api.github.com/users/code-dot-org/followers","following_url":"https://api.github.com/users/code-dot-org/following{/other_user}","gists_url":"https://api.github.com/users/code-dot-org/gists{/gist_id}","starred_url":"https://api.github.com/users/code-dot-org/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/code-dot-org/subscriptions","organizations_url":"https://api.github.com/users/code-dot-org/orgs","repos_url":"https://api.github.com/users/code-dot-org/repos","events_url":"https://api.github.com/users/code-dot-org/events{/privacy}","received_events_url":"https://api.github.com/users/code-dot-org/received_events","type":"Organization","site_admin":false},"private":false,"html_url":"https://github.com/code-dot-org/code-dot-org","description":"The
