Subject [jira] [Commented] (CB-638) Slow native bridge (especially android)
Date Thu, 13 Sep 2012 02:53:07 GMT


Andrew Grieve commented on CB-638:

Other things to sanity check - when benchmarking make sure you don't have a USB connected
(adb bridge slows things down). 

I also made sure to launch the app using the "Run" action instead of Eclipse's "Debug" action.
Debug vs Release makes a difference on iOS, but I'm not sure if there's a difference for Android

>'s native bridge is more than 5 times faster than Cordova (on Android).
> I'd love to see similar performance stats in Cordova.
