SQL Server CPU Utilisation won't exceed 10%












0















We have a virtual machine running in Azure. When i remote onto the server box desktop and run SQL queries, each query connection will only use 10% of the processing capability of the server. When i simultaneously open two or more connections in SS Management Studio, each query will use 10%. E.g. if i have three connections open running queries, the CPU utilisation will go up to 30%.



Is there a way to change this? I would like each process to be able to utilise more CPU power. There are 16 virtual cores, 112 GB memory.



I'm running CPU work only queries to test, so there aren't other bottlenecks at play for instance io/network/disk limitations.



I've tried stored procs, and stored procs within jobs and the CPU utilisation still remains at 10%.



I've had a good look around the SQL server properties and the virtual machine properties and can't seem to find a setting to change this.



Hope someone can help,



cheers.

  • (I fo postgres, not sql server, so I could be way off base). It sounds like you are either trying to use a single table so sql server can't split the query to parellise it or that it doesn't have the ability to split queries.
