My Setup:
- iOS 9.2
- Xcode 7.2
- Appium 1.4.13
When you build, did you point to the right version of simluator? i.e. 9.2 in your case? I had the same issue when I pointed to, i.e. 9.1 but i launch a 9.2 simluator and hence I see no increase in test run performance
Pay attention to this when you ./build.sh
SDKROOT = iphonesimulator9.1
