Slow navigation after upgrade to Dashboard 4 sp2 from Xcelsius 2008 sp5

Hi,

I am experiencing slow navigation on click on menu items, radio button after upgrading to Dashboard 4.0 sp2 fro Xcelsius 2008 sp5. My dashboard contains vlookups and its based on BI Services. Clicks use to take about 3-5 sec in Xcelsius 2008 now taking 10-15 sec after upgrade. Does anybody have similar experience or any solution workaround?

Thanks in Advance

Kumar
