How to make faster scroll effects?

• Avoid too many reflows (the browser to recalculate everything)
• Use advanced CSS3 for graphic card rendering
• Precalculate sizes and positions

Beware of reflows

The reflow appens as many times as there are frames per seconds. It recalculate all positions that change in order to diplay them. Basically, when you scroll you execute a function where you move things between two reflows. But there are functions that triggers reflows such as jQuery offset, scroll... So there are two things to take care about when you dynamically change objects in javascript to avoid too many reflows:

Monitor is a simple HTML/JS based application. It allows requesting JSON apis, with an history.

This gist is used to try the demo requests on start.

Lately, with the help of Julien Tournay, I wondered how can we resolve the model problem in the browser which is : there is no ONE true model, and one information can be duplicated in multiple places (eg: form, list, item). Finally, I found out that the real datas are from : the forms > the server > the DOM. Meteor solved this by keeping this order, and synchronize it all in real time ! That's truly great. But. There a hudge cost in this : you have an heavy fullstack architecture, and you can't have control on the async which is black magic. Also, It's made for realtime, so concurrency apps. With Node.js in one thread, I can't imagine an app with thousands of users at the same time managing as much states properly. There is no holly grail. Just code!
