I am mobile device web middleware developer, and I have to check some webapp's performance (not an Android, not an iOS device).
Those webapps (not a web service or web page. those are a kind of hybrid app) are very device dependent, so I can't use desktop Chromium dev tools.
Below is desktop Chromium performance dev tool.
I want to know "Loading time, Scripting time, Rendering time, Painting time". How can I check those things on mobile device?
Command line interface, logs, anything is okay...
