Sm 7.1. - IT Servicemanagement Performance Tuning

Hello experts,

we are using IT Servicemanagement of Solution Manager 7.1 SP 8.

This is based on WebUI.

But the performance is not very good.

Only at opening an incident/change request you get the Loading-Circle.

Or if you select en entrie from a drop-down menu also the loading-circle.

Does someone know some performance-tuning-guides for this?

We are not facing any server-problem (no memory issue, no cpu issue, ...)

Kind regards
