Hi All,
I just experienced that SQL Server 2014 Standard has high CPU Usage(around 35%) when idle status.
I am using SQL Server 2014 on AWS EC2 c3.8xlarge(32 cores vCPU) instance with Microsoft Windows Server 2012 R2 with SQL Server Standard.
After launched the instance, I didn't touch anything on the instance. It means the instance is initial-state and idle status.
I also tested it on some other instance types.
For i2.8xlarge, cr1.8xlarge which has 32 cores vCPU, all their CPU Usage is same(around 35%).
But for c3.4xlarge, i2.4xlarge which has 16 cores vCPU, all their CPU Usage is around 5%.
Anyone knows the reason why virtual server with 32 vCPU cores has high CPU Usage?
