Measuring Perf of Cordova apps (Android/iOS)
Over the weekend, I created a tool to measure the rendering and network
performance for Cordova apps, and I thought of sharing it on the list. I am
able to pick up numbers from iOS and Android (4.4).
Here is a demo video - https://www.youtube.com/watch?v=TG_eTe_H-s4
More details on how to run it on your cordova app : [link
<http://blog.nparashuram.com/2014/10/measuring-rendering-performance-metrics.html>
]
Browser-perf : http://npmjs.org/package/browser-perf
Would love to hear feedback from the community on this. Initial tests with
WkWebview and UIWebView show some good numbers.
Since a lot of people worry about perf of hybrid apps, I am hoping that
this tool would give them a way to look at hard numbers and see that hybrid
apps can be as smooth as native apps.

I was thinking you could just write a post that links to your
already-excellent post here:
http://blog.nparashuram.com/2014/10/measuring-rendering-performance-metrics.html
You'd be the first post to be re-posted on the Cordova blog, so you'd need
to do some work to figure out what format's best, but I think pretty much
anything would do :P

@Michal - I tested the WkWebView using a simple iOS App and loaded a webpage on it - not Cordova yet and that was the reason I did not publish the results. Can't wait for WkWebView to be in Cordova and then see how much of an improvement we could get :)
For the metrics, the idea was not to compare iOS vs Android, but rather compare 2 deploys of the same app. This idea is, a developer runs the tests per commit (in a continuous integration system) and can see which commit slowed down the app. This way, they could also figure out the CSS or JS event handlers they added during that commit. The graphs would look something like http://nparashuram.com/perfslides/perfjankie - you can see how the 3rd commit on that graph is bad since I added an onScroll event handler.
@Andrew - I would love to do a blog post. Should I write it on my blog and refer to it in the official Cordova blog, or can this be in the official cordova blog? Note that I developed this tool independently and is not an official Cordova release, but if the folks in the community feel that this could be interesting to any Cordova developer and makes sense to put in the official Cordova blog, I would love to write a quick tutorial.

Super Cool. This would definitely be useful to add to a continuous build system. Certainly would make a good referral blog post if you want to have a stab at it :)

Very cool Parashuram.
How did you test WkWebView? non-cordova?
Also, the results have different labels on iOS/Android, which I assume
means you are just reporting what the tools report. Would you consider
mapping the values which have direct parallels to the same labels so we can
do more direct comparisons?
