-----------------------------------------

I'm sure you have a benchmark that shows that this is a problem in multi-user database applications with real datasets and concurrency?

> render time if/else tags to avois excessive calls in rendered attribute
> JSF doesn't have if/else render time tag construct.
> So if you have many if/else conditions you end up writting rendered= attribute with those conditions
> and call the same bean methods all over again. 
> This significantly impacts performance.
