SQL Server On Linux: Will It Perform Or Not?
Will SQL Server perform on Linux better than on Windows? Have you been wondering whether the multi-layer architecture the team revealed recently will hurt SQL Server’s performance? Are you still not convinced about the entire endeavor. Come, listen to the talk, learn about SQL Server’s...
cgroupv2: Linux's New Unified Control Group System
cgroupv1 (or just "cgroups") has helped revolutionise the way that we manage and use containers over the past 8 years. A complete overhaul is coming -- cgroupv2. This talk will go into why a new control group system was needed, the changes from cgroupv1, and practical uses that you can apply to...
The Modern Operating System in 2018
The last monolith is the operating system. There are tens or hundreds of millions of lines of code in the kernel, and orders of magnitude more in the userspace code that gets shipped with it. Not just any code, security critical code written in unsafe languages. Every other area of software has...

Why aren't operating systems more like applications?We live in an era of application microservices, even nanoservices. Each application serves precisely its purpose, living for exactly how long it needs. When we need it to do something else, we either create a distinct service, or rebuild...
Understanding CPU Microarchitecture to Increase Performance
Microprocessors have evolved over decades to eke out performance from existing code. But the microarchitecture of the CPU leaks into the assumptions of a flat memory model, with the result that equivalent code can run significantly faster by working with, rather than fighting against, the...

SQL Server On Linux: Will It Perform Or Not?
What have you been working on recently?
Two years ago there was a business decision to put SQL Server on Linux; so, as the engineering team, we have to figure out the “How” part. The task is technically challenging: tens of millions of lines of code that continues growing on a monthly basis, with over 500 developers working on it. The Drawbridge project, which I became...

What's the focus of your work today?
I'm playing in a few different areas all related around technology and operations. My focus tends to be where do changes in technology or engineering lead to fundamental changes in how individuals and companies operate. Sometimes it's a little bit more about the tech, sometimes it's a little more about operations and organization, but...
