How to improve Portal Page Rendering Performance?

When you install WebSphere Portal, you always have noticed that when you login to the server very first time, it takes some extra loading time for each JSP page. That extra load time is because of the fact that each JSP page on server must be compiled first time its is accessed, so in order to improve load time you can make use of precompile-jsp command.

1. From the command prompt, navigate to this directory


wp_profile\ConfigEngine (For WPS 6.x.x)
wp_profile\bin (WPS 7.x)

2. Run the following command


ConfigEngine.bat precompile-jsp –DWasUser=USER – DWasPassword=PASS
