JSF slow page loading problem

[ynscn]

Hello everyone,

In the project i'm working on, we have an information page, which takes a lot of time to get loaded. The page has more than 3000 lines with dialogs and tabs, and each tab has a datatable. I was loading all of that tables data before the page's rendering. I thought that was the main reason for slow loading and i made them load when a particular tab is selected. But it didnt make the rendering part any faster. Now i think thats because of the page is too big. By any chance can i make it faster other than seperating each tab and dialog into a new page ?

I'm using Primefaces 3.5 with Seam 2.3 and JSF 2.1

Thanks

Otherwise your application logic may be slow.

Try a profiler to see where the bottleneck is.

Otherwise your application logic may be slow.

It takes approximately 3 seconds to load, but sometimes it can be more than 10 seconds. And for the AS i use JBoss, maybe there can be some configration to make it faster?

Thank you so much for your tips, i'll try them

Try a profiler to see where the bottleneck is.

How can i use a profiler? And are 3000 lines too big for a page? I'm really getting suspicious about it.

We had a page with ~2000 lines in a ui:repeat and some el and conditions.
I took arround 800ms for rendering (without query) with plain Tomcat and with this tips on my blog.
Without ExtVal ~700ms.

It really depends on your app. First i would try MyFaces and please measure the rendertime with a PhaseListener or Filter and multiple calls (because of warmup).
