| ### When not to use MST? | ||
| MST makes state management very tangible by offering access to snapshots, patches and by providing interceptable actions. | ||
| Also it fixes the `this` problem. | ||
| All these features have the downside that they incur a little runtime overhead. | ||
| Although in many places the MST core can still be optimized significantly, there will always be a constant overhead. | ||
| If you have a performance critical application that handles huge amounts of mutable data, you will probably be better | ||
| off by using 'raw' mobx. | ||
| Which has predicatable and well known performance charasteristics, and has much less overhead. | ||
| Likewise, if your application is mainly dealing with stateless information (such as a logging system) MST doesn't add much values. | ||
