Performance issue with Super User

We are using Piwik to track some intranet applications in our Company. Ever since we moved to Piwik 3.0, we notice that Piwik Portal is extremely slow(~40 seconds to load) only when accessed by user name which has Super user privileges.

If we use any other credentials with view or admin privileges, all the pages/widgets/dashboards load pretty quickly (~5 seconds). I tried creating new user and test Piwik dashboard Performance before and after giving Super User privileges and the difference is stark.

Can you please help resolving this issue?
