When I joined Netflix in April 2014, we had over 40 million subscribers in 41 countries. In the last three years I developed the ftrace-based [perf-tools] and used them to solve many problems, which I wrote about in [lwn.net] and spoke about at [LISA 2014]. We are now in 190 countries and just crossed [100 million subscribers]!

Finding a small number of distinct values might seem like quite a specific requirement, but I have come across it fairly frequently over the years, usually as part of tuning a larger query.

For SQL Server 2008R – 2014, you could lower this threshold using trace flag 2371. If you are on SQL Server 2008 – SQL Server 2014, for a single NUMA node with less than 8 logical processors, keep MAXDOP at or below the number of logical processors. That can take a long time on larger tables. SQL Server Agent Alerts.

Back in 2014, I started a series of blog posts here to talk about specific wait types and what they do and don’t mean. Understanding what these mean and how to investigate them is critical so you don’t succumb to what I call ‘knee-jerk performance tuning’ and waste time and effort trying to fix a problem that isn’t actually a problem.

SQL Server 2014 SP2 and later produce runtime (“actual”) execution plans that can include elapsed time and CPU usage for each execution plan operator (see KB3170113 and this blog post by Pedro Lopes). This can make it difficult to draw sound performance-tuning conclusions.

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). If that seems wildly unacceptable, note that you can tune overcommit on Linux to not do this, and behave more like Solaris (see sysctl vm.overcommit_memory).

To provide some coherence to the music, I decided to use Taylor Swift songs since her discography covers the time span of most papers that I typically read: Her main albums were released in 2006, 2008, 2010, 2012, 2014, 2017, 2019, 2020, and 2022. This choice also inspired me to call my project Swift Papers.
