Are you a java web application developer and you are working with JBoss Seam? Ok, then you might be interested in the following JBoss Seam performance problems (and their solutions). If not you should seriously consider leaving this post! It is rather long and dry and might make you never consider programing with Seam EVER (which can also be a good thing, but I will leave this discussion for another post). In any case: You have been warned.

Soo… I have recently gained some experience developing a medium/large web application with Seam and I also discovered a couple of pitfalls you run into when using this framework, especially in terms of performance optimization. At some point, I had pages of just average complexity, loading in more than 17 seconds! In this post, I will go over each of the steps that i did to speed up those pages to 3 – 6 seconds. During my code analysis, I searched through a couple of Seam performance tuning pages out there, but for some reason they did not really provide me the tweaks or straight solutions I was hoping to find. Many of the tips I found sounded very reasonable, but when I applied them to my project, there was barely any change in Seam’s performance! That’s why I publish my own list of performance optimizations, which definitely had a visible impact at least on my code and hope I can help those among you, who find themselves in a similar position like me. And even if my performance tuning tips are not able to help in your particular case, at least you will learn how to identify performance problems in your Seam project with this post.
