Hi Adam

We have an old spring project using JSF and Dozer mapper , this project is destinated to large public of users ,
so we have performance issue even with an architecture of clusters.

my team thinks that JSF is one of the reasons to this lack of performance and they suggest to replace it with Angular. we are constrained by deadlines and we havn't a good experience with angular.

• Is there a good performance benfit of using an SPA framwork like angular over JSF .?
• Is it a good idea to use JSF with spring and could that has an effect on performance ?
• In which case we use dozer because from my point of view it's not neccerary to use it ecpecially with JSF and with new
  JPA features ?

Thanks
