Since yesterday, when Oracle Fusion Middleware 11g became available, I have done quite extensive testing on previously known ADF problematic areas.
Cool thing is that page load time even for complex pages is much faster now on runtime. Its because previously on page load, SQL queries for all available LOV components were sent to database. So, if page contains 20 LOV components, means 20 SQL statements were sent to database, it was killing performance especially when working on larger datasets. Now its fixed, and on page load SQL queries for LOV components are not pre-executed anymore - only main SQL statement is executed. Means - page load performance improved significantly.
In my next post I will describe how to tune your ADF application design in order to get high performance in CRUD applications.
