Improving SilkMobile Execution Performance

We are currently automating tests using the latest version of SilkMobile for our Native Application across Android and iOS (this issue is irrespective of OS version). Although functionally tests are working as expected, we are experiencing very slow execution time of around 2-3 minutes for a test to execute. We have quite a big and robust framework that we've developed, but this time is extremely high and we urgently need to bring this execution time down. When you use the app directly, it is very fast and responsive, but through SilkMobile a device response is a lot slower.

The app is a typical banking app and we expect execution to be very responsive. 

Are there any settings or anything we can do in SilkMobile to improve execution time of our tests?
