The changes made in SQL Server 2017 CU4 improve resource usage on smaller machines, such as a VM or Container used for testing and development. The change I made in SQL Server 2017 CU4 was to consider RAM as another factor in the default calculation. For SQL Server 2017 CU4 the small environment threshold is 2GB.

My last talk for 2017 was at AWS re:Invent, on "How Netflix Tunes EC2 Instances for Performance," an updated version of my [2014] talk. WARNING: These tunables were developed in late 2017, for Ubuntu Xenial instances on EC2.** I shouldn't let this go to my head, as there were 42,000 attendees at re:Invent looking for something to see!)

Xen AWS 2017 In 2015, AWS launched c4, which used hardware virtualization for EBS volumes. This finally came to storage-optimized instance types in 2017 with the [i3 instance type], which used SR-IOV and the nvme storage driver. With a solution in hand for network performance, the next target was storage. ## 6. 0% performance overhead.
