KPI list loading very slow

Hi,

We have some KPI lists on our sharepoint 2010 site. Some of them take really longer to load. It's not a very large site around 38 GB. There are only 10-15 items on each KPI list.

When we move the KPI and source list to test site it seems to work fine.But on original site it seems to be very slow.

Any suggestions.
