Hi Experts,

Would like to reach out to you for some advise to enhance the performance of our stage environment.

We understand that stage environment's system performance is not being looked after; however, the symptom of our Fusion test environment running super slow is noticeable after we have the data dumped from production environment just this weekend.

May I ask if there is anything we can do, like archive some of the transactions, or any scheduled processes we can run to lighten our test environment, so that it would probably run faster?
