Oracle VM Server is based on Xen. Both Xen and KVM have had many performance and security improvements, and workloads can now be tuned to run at almost bare metal speeds (say, a 3% loss or less). Outside of EC2, many other providers are deploying on KVM. I also wrote and published an entertaining SMF manifest that played music.

I’m going to introduce you to wait statistics and explain how critical they are for troubleshooting workload performance in SQL Server. The execution of SQL Server’s internal code is done using a mechanism called threads. When that happens, SQL Server makes a note of why the thread had to wait and this is called the wait type.
