I have so far avoided writing such pointer blog posts which only refer you to another article, but I have to do it with this one. Adrian Billington has written an excellent article on performance of Oracle 11g PL/SQL function result cache. His article is a good example of a thorough, well organized and well written technical content. I really enjoyed reading it and thanks to his thoroughness, he has just saved me some precious time doing that research on my own.

Thanks indeed for this very useful article.
