I came across <<http://jsblocks.com/(jsblock)>> yesterday on Hacker News. They had a nice performance comparison test case set comparing jsblocks with <<https://angularjs.org/(Angular)>> and <<https://facebook.github.io/react/(React)>>. It made me curious to see how the small library we use (<<https://github.com/vpj/weya(Weya.coffee)>>) compares in performance with these. >>> Weya.coffee is more of a rendering tool than a a framework. The main difference between Weya and other frameworks is that instead of writing logic inside html, markup is written in coffeescript. Weya comes with a router and a base class inspired by <<http://backbonejs.org/(backbone.js)>>. <<< <iframe src="https://ghbtns.com/github-btn.html?user=vpj&repo=weya&type=star&count=true&size=large" frameborder="0" scrolling="0" width="160px" height="30px"></iframe> I ran the tests on Chrome broswer on a Macbook Air (1.6Ghz i5, 2GB). I have not altered test cases provided on <<http://jsblocks.com/(jsblock)>>, and have added test cases for Weya for **Rendering** and **Syncing Changes**., The results on Safari are not accurate in --syncing-changes-- test case, because jsblock test case use ``setTimeout(0)`` to resync which is called before html is actually rendered while the Weya test case use ``requestAnimationFrame`` which waits till it's rendered. >>> **<<http://vpj.github.io/jsblocks-performance.zip(Download the performance test cases)>> ### Rendering ||| Library | Time (ms) |Bar (shorter is better) === Weya.coffee | 404 | ==== jsblocks | 801 | ======== React | 1065 | ========== Angular | 2432 | ======================== ### Syncing Changes ||| Library | Time (ms) | Bar (shorter is better) === Weya.coffee | 1593 | ======== jsblocks | 2035 | ========== React | 2781 | ============== Angular | 8081 | ========================================
