I Agree with Harshad, Slow load time for GUI with DAS single instance is
been there all the time, and I always have to clear cache and do shift
+reload to refresh the screen.

It shows the time it takes for Admin Console screen to show up in the GUI, after entering the URL in the browser, and pressing return. In case of https, the time is counted after confirming security exception prompt. This is by no means any methodical performance test, but simply shows "perceived load time" on the Solaris 10 Sparc machines (Niagara, T1000), that I use for day to day testing.
