Simple answere: no. I will have to profile your application to find out where your CPU bottleneck (if it's a CPU bottleneck) is, or where your network bottleneck is. Because JSF uses value binding which can do lots of things, any badly written/badly used bean can be at cause (like a bean loading 50.000 items for a database at each request). Simple suggestion: when you load a JSF page, go in a console to your solaris station and run a kill -3 <JVMpid>, this will dump to the jvm's stdout a stacktrace of all running threads. From there you could see where the code is waiting / busy.
could it be some xml parser uses a xsd/dtd which is not available. If production server is firewalled, maybe the server is just trying to download the schema/dtd and finishes on a timeout of approx 4 seconds? > > I am using Myfaces & tomahawk 1.1.5, Weblogic 8.1sp4, Facelets > 1.1.12.
