Minimal Download Strategy in SharePoint 2013/2016/Online

In the web application concept where the user sends a request and got a response back, the whole web page will be reloaded even if you update the whole page or a part on the page. And this causes some performance issues for the end-user like page loading time etc.

SharePoint 2013 introduced a new feature known as “Minimal Download Strategy (MDS)“. This feature allows for partial page download which basically speeds up page rendering.

When MDS is enabled all pages for that site are rendered through the /_layouts/15/start.aspx page like when you request the home page or any other page then it will be like below:

URL when MDS is NOT enabled: http://site/SitePages/Home.aspx

URL when MDS is enabled: http://site/_layouts/15/start.aspx#/SitePages/Home.aspx

Internally the start.aspx page has a specific JavaScript object asyncDeltaManager which is responsible for this activity.
