When you first start Portal 6 up (or Portal 5.1 for that matter), no matter what gear you are running it on, its going to seem slow. If you are doing an install, or planning on doing one, add this to your post-install task list:
wpsconfig action-precompile-jsp
This will precompile all JSPs within Portal. It will also take a LONG time to run (mine ran at 477+ minutes on a single processor, 2GB VM).
Plan on running this before you deploy to your user community.Labels: java, performance tuning, Portal, WebSphere
