platform.js eval time at page load

[PBK]

Polymer team,

I am seing evaluation times for platform.js in the 6 to 7 sec range on Chrome 33 on on Android 4.4.2.  

Is that within the performance range we should be expecting or is will the load speed performance be significantly improved moving forward ?

[PBK]

Any insight on that ?

thanks !

My understanding is that the focus now is less on performance and more on getting the standards nailed down and feature set locked. Once the features are shipping browser-native obviously performance will tremendously improve.

Of course I'm not core team so I could be wrong :)

Hi PBK,

On Chrome 33, Android 4.4.2, over wi-fi, loading + executing platform.js from polymer-project.org takes ~400-600ms for me: http://jsbin.com/tuwufelo/1/quiet

Obviously network plays a factor in load time, but can you explain more how you're getting 6-7s?

FWIW, we're always looking at how to make platform/polymer faster, but as Michael mentioned, the end goal is to target browsers with the native APIs. platform.js goes away over so there's less incentive than making the native fast paths, faster.
