I mentioned this Club thread in the chat as a great reference for some performance testing tools Performance: which testing tool and why?
Another great thread Site Speed Tools.
A recent blog post from @marie.drake that folks who attended should read 
Questions we didn’t get to
- @fullsnacktester: Can you use Apptim with cloud based device farms, like AWS or BrowserStack?
- MJ: Can we record our test session and rerun it automatically after each release?
- @aishwaryakamath: Are you using AWR reports for performance statistics if yes could you please explain.
- Steven W: Does apptim work with Apps created with Xamarin? Can it be used with Xamarin automated tests?
- Kristof: Would you have done something different building your app if you could start over?
