Hi All - We have built a J2EE application with JSF (MyFaces, Ajax4JSF) ,Spring
and IBatis. What we find is, each of the screen takes lot of time to load. We
find no performance issue with Spring or Ibatis (after verifying via
JProfiler). Jprofiler shows the JVM memory is occupied b JSF objects. I found
that the screen loading is taking time for two reasons.
1.The JSF screens (which has cook menu) take time to load.
2.The overall screen painting in the browser takes time to load.
Our JSF screens are not too complicated and even the simplest screen takes time
to load. Note that each of the screens always loads JSCookMenu. We visited
apache site for tuning JSF. As per their suggestion we did the following
1. We set the State saving mechanism as server side.
2. Serialization of session objects was set to false.
3. Compression of objects was set to false.
4. Streaming Add Resource and t:documentHead were added.
But none of these improved the performance.
The overall screen takes time and I'm wondering if we should do effective
caching of images,CSS and js files. I visited plenty of websites and tried to
move all these client specific files under the <head> tag, loaded the images
via CSS but nothing helps. We have high capacity machines and I dont think
desktop config is playing a role.
We thought the problem could be bcos of network traffic or slow performance of
underlying platform websphere server. We checked other application running in
the same envrironment and they are extremely fast. The only difference b/n our
application and the other is JSF.
I'm short of solutions. Any valuable input will be greatly appreciated.
