I have Hyper-V environment running an application. It had been running for 3 years. I never had any slow performance issue on Saturday until a US client started using our application. Every Saturday morning from 2.00am - 3.00am. The performance on the application is really poor. Unable to do anything. A new user can not login. But when this spell is over, everything becomes normal.
Initially I thought it is weekend backup or SQL maintenance. But I moved everything from this time. Now there is no backup or SQL maintenance running at the moment. However, this slow performance spell still happening.
I want to check here if there is any other parameter in the Microsoft Hyper-V environment which really causing this issue.
Can someone guide me in this
