SQL Server 2014 Standard has high CPU Usage on Amazon AWS EC2 c3.8xlarge Instance.


hi all,

i experienced sql server 2014 standard has high cpu usage(around 35%) when idle status.

i using sql server 2014 on aws ec2 c3.8xlarge(32 cores vcpu) instance with microsoft windows server 2012 r2 sql server standard.

after launched instance, didn't touch on instance. means instance initial-state , idle status.

i tested on other instance types.

for i2.8xlarge, cr1.8xlarge has 32 cores vcpu, cpu usage same(around 35%).

but c3.4xlarge, i2.4xlarge has 16 cores vcpu, cpu usage around 5%.

anyone knows reason why virtual server 32 vcpu cores has high cpu usage?

hello,

that instance has sql server 2014 no updates installed. please apply cu2 sql server 2014 or request update instance, since cu2 has fix related high cpu usage.

the update can obtained following link:

hope helps.

regards,
