Measuring the user experience of dApps

Is it a well known fact that dApps are substantially slower and that users reduce their expectation when it comes to response time, and do users also put up with the more complex security and password management requirements that comes hand in hand with the encryption applied to the transactions?

Has there been any studies on the difference in the expectation and experience of users when it comes to using a decentralized application (dApp) compared to normal apps?

Some requirements of dApp design can be found in a previous question: User interface for distributed and open/public (e.g. blockchain-based) applications
