Disable Unnecessary SQL Server Instances And Services

Why should you care about services that are not needed?

You may be wasting your precious resources on unused services.

It would be best if you prioritize your more critical SQL Server instance to use more resources and do not allow less important ones to take all of them.

How can I list all the SQL Server instances and services?

  1. Click Start and search for “configuration”.
  2. Open SQL Server Configuration Manager and choose SQL Server Services.

Also, you can list all instances installed using the T-SQL code below.

EXEC master.sys.xp_regread @rootkey = 'HKEY_LOCAL_MACHINE'
	,@key = 'SOFTWARE\Microsoft\Microsoft SQL Server'
	,@value_name = 'InstalledInstances'

How can you fix them?

  1. Disable the SQL Server instances and services that are not used.
  2. Adjust the max memory, the threshold to parallelism, and MAXDOP settings for all instances appropriately.

Red9 has incredible expertise both in SQL migration and performance tuning.

The biggest benefit has been performance gains and tuning associated with migrating to AWS and a newer version of SQL Server with Always On clustering. Red9 was integral to this process. The deep knowledge of MSSQL and combined experience of Red9 have been a huge asset during a difficult migration. Red9 found inefficient indexes and performance bottlenecks that improved latency by over 400%.
