The applications have a terrible delay in response after upgrade

Hi,

We upgraded our current BI 4.0 sp06 system to BI 4.1 sp05. After the upgrade all the tools seems to be responding terribly slow or no response at all.

to list a few

Launching web based applications launchpad / cmc - response time more than 10 mins and sometimes no response at all (doesnt bring back any page -just blank)

Looking into CCM- does not  bring the list of services or gives a transport communication failure error

Logging into the client tools ( Webi rich client/ UDT/ IDT) - response time is atleast 5- 10 minutes.

Has any body come across such issue? Please advise.

Thanks,

Shaheen
