SQL Server According to Bob

NOVEMBER 29, 2016

Back in June, Bob Dorr gave you the thinking behind why SQL Server 2016 It Just Runs Faster due to changes in our SQL Server and NUMA configurations. Bob blogged about a new SQL Server 2016 feature called Auto Soft NUMA. What does this look like in a Virtual Machine? So back to our original server.

more capable, and built from the ground up for the modern era of the eBPF virtual machine. eBPF was created by Alexei Starovoitov while at PLUMgrid (he's now at Facebook) as a generic in-kernel virtual machine, with software defined networks as the primary use case. It's shaping up to be a DTrace version 2.0: eBPF does more.

Hardware virtualization for cloud computing has come a long way, improving performance using technologies such as VT-x, SR-IOV, VT-d, NVMe, and APICv. It's an exciting development in cloud computing: hardware virtualization is now fast. Virtualized in Hardware**: Hardware support for virtualization, and near bare-metal speeds.

As Slava highlights in his recent blog post , he also contacted me in early 2015 to assist with supportability of SQL Server on Linux. By March of 2016 Slava had convinced me to join the team. Find those same concepts for software and you can do the exact same things, no virtualization and no performance or functionality compromises.

I recently visited a customer onsite and presented to them topics on SQL Server 2016. When I got back to my office, I remembered my colleague from the Tiger Team, Ajay Jagannathan, had blogged about new extended events we introduced in SQL Server 2016 for backup and restore. OK, this is very cool.

Mike Gualtieri of Forrester Research, who coined the term NoOps , once said in his blog post, “NoOps means that application developers will never have to speak with an operations professional again.”. NoOps is a concept in software development that seeks to automate processes and eliminate the need for an extensive IT operations team.

The transaction log contains virtual log files, which contain log blocks, which store the actual log records. Virtual Log Files. The transaction log is split up into sections called virtual log files , commonly just called VLFs. I explained an example of the difference in this blog post.

LTS (April 2016). I wrote about it in a previous post, [DTrace for Linux 2016]. I wrote a page on it: [perf]. - **eBPF**: tracing features completed in 2016, this provides efficient programmatic tracing to existing kernel frameworks. The hardest part on Linux is now done: kernel support. It's the official profiler.

I wrote a blog about it years ago too, however as time has marched on, guidance has changed a bit. Jonathan Kehayias has written an blog post How much memory does my SQL Server actually need , with a formula that helps establish the baseline for the maximum memory value. SQL Server 2016 introduced soft-NUMA nodes.

Correspondingly, 3GB functions should see a 2x CPU performance improvement over 1.5GB Lambdas, but this is through doubling the number of cores the function has access to, rather than double the virtualized time-slices. We haven’t tried out SAR yet since it was only pre-announced, but when we do we’ll give an update here, on the blog.

At the time of the last Confluence run, the gap had stretched to nearly 1000 APIs, doubling since 2016. Now in development in WebKit after years of radio silence, WebXR APIs provide Augmented Reality and Virtual Reality input and scene information to web applications. But perhaps counting APIs gives a distorted view?
