MobX vs MobX State Tree vs MobX KeyStone for performance?

To put it simply, I have a very performance heavy/critical real-time data application that currently uses Mobx-State-Tree. I'm running into issues with performances, specifically excessive re-renders, and was tasked with looking into alternatives to MobX-State-Tree that might be better suited. Would either of the other MobX tools work or should I be looking elsewhere
