What article did you read that in? How are you defining a 'big project' and a 'large number of concurrent usrs'? We are using JSF (MyFaces and Trinidad) on several projects and have load tested with over a thousand concurrent user and have not experienced any issues. The key to scaling any application is to make sure objects are stored in the shortest scope as possible to decrease the memory footprint. Conversation scope is very useful for this. It is is true that any poorly designed application probably won't scale very well. How big is the server that you are planning to run on in production?

LS,

I read recently, that JSF is not well suited for big projects, as it faces scalability issues when the number of concurrent users of the webapp grows.
This is due to the controller beans that get instantiated per user.
Therefore, so the article stated, it is advisable to use another framework
for big projects.

I would like to know if there is any truth to that, if JSF is indeed less
scalable than say struts2.

Thank you,
