Poor performance when using cordova, How can I profile?

I’m facing a strange issue with an app I working on, that mainly targets Microsoft surface.

Although I’v read that ionic framework doesn’t support the MSFT tablet, I found a HUGE performance gap between using Microsoft Edge and the same app packaged with cordova…
Ex. ion-scroll is ok on Edge but unusable on Cordova on the tablet.

Any idea why such a difference ? (Is there a tip like activating GPU on Windows webview ?)

Also is there a way to profile an app running on a windows tablet ? I’d like to have something like Chrome flamechart or frame profiling.
