Subject [jira] [Commented] (CB-638) Slow native bridge (especially android)
Date Thu, 13 Sep 2012 00:17:07 GMT

    [ https://issues.apache.org/jira/browse/CB-638?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13454508#comment-13454508

Andrew Grieve commented on CB-638:
----------------------------------

Yep, everything's in there. Your numbers do at least show the same relative speeds (online
being the fastest async case). It shouldn't be the case that sync would ever be slower than
async though. That makes no sense whatsoever.

I used the my manual test page to do all of my timings, tomorrow I'll try it with your more
automated one and see if the numbers look any different.

For SYNC and prompt/js_object, no need to test with different Native->JS modes. They won't
even come into play.

> Doing many native callbacks (such as writing files) has a significant overhead.
> Trigger.io's native bridge is more than 5 times faster than Cordova (on Android). http://trigger.io/cross-platform-application-development-blog/wp-content/uploads/2012/02/chart_1-21.png
> I'd love to see similar performance stats in Cordova.
