I deploy the app as Mobile. How do i improve on PowerServer Performance and network latency?

Excellent. Deploying as Mobile only enhances (tailors) the code generation for Android and/or iOS devices.

For overall PowerServer responsiveness ... you can check out the Sales "Demo" app in your web browser and also deploy your mobile app as "WEB". If the web version responds fast in the browser, then PS itself is most likely working well.

The PS installation also includes a "Sales Mobile" demo App. If you run that on your mobile devices and they do *not* work well. Then network latency would be the issue.

For network latency, my mobile framework records this by using the "appeonextfuncs" object class in the PS's "workarounds" PBL. In there, it then uses the "of_networktest" method to get the network's performance level at start-up. If this number is very low (ie: 16ms) then the network and PS for that matter are responding very well. If this is a high number (ie: > 250ms) then I know latency issues are probably affecting my PS App (either: Mobile, Web or IWA deployed). From there, I would normally speak with my network support team as to the possible reason(s) for this slowness.

Will you advice on Recommended Ram size and processor ?

So that i may look at them also.
