‚ÄčI made the post sound like a tutorial, hoping that it would help
developers get started quickly with perf for Cordova apps.

Would greatly appreciate any feedback on the content and the tool :).

already-excellent post here:

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 - you can see
how the 3rd commit on that graph is bad since I added an onScroll event

@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 :)
