Well,
There is a backup agent installed, and it runs only at night. Durning the day there are multiple processes running in SQL that point to the backup agent that are slowing down the server. If I stop the agent service, and kill the processes, the server will speed up. I will then turn back on the agent and no processes will be running.
The next day I will have to repeat the process. Is as if the sql backup is not closing the processes at night after the backup is done.
