<p><strong><a href="http://www.stevesouders.com/blog/2010/07/09/diffable-only-download-the-deltas/">Diffable: only download the deltas</a></strong></p> JavaScript library for detecting and serving diffs to JavaScript rather than downloading large scripts every time a few lines of code are changed. “Using Diffable has reduced page load times in Google Maps by more than 1200 milliseconds (~25%). Note that this benefit only affects users that have an older version of the script in cache. For Google Maps that’s 20-25% of users.” <p>Tags: <a href="https://simonwillison.net/tags/google-maps">google-maps</a>, <a href="https://simonwillison.net/tags/javascript">javascript</a>, <a href="https://simonwillison.net/tags/performance">performance</a>, <a href="https://simonwillison.net/tags/steve-souders">steve-souders</a>, <a href="https://simonwillison.net/tags/recovered">recovered</a>, <a href="https://simonwillison.net/tags/diffable">diffable</a></p>
