December 11, 2019Dec 11, 201912/11/19.NET added async/await to the languages and libraries over seven years ago. In that time, it’s caught on like wildfire, not only across the .NET ecosystem, but also being replicated in a myriad of other languages and frameworks. It’s also seen a ton of improvements in .NET,
December 11, 2019Dec 11, 201912/11/19“Producer/consumer” problems are everywhere, in all facets of our lives. A line cook at a fast food restaurant, slicing tomatoes that are handed off to another cook to assemble a burger, which is handed off to a register worker to fulfill your order,
December 9, 2019Dec 9, 201912/9/19We open sourced our new GC Perf Infrastructure! It’s now part of the dotnet performance repo. I’ve been meaning to write about it ‘cause some curious minds had been asking when they could use it after I blogged about it last time but didn’t get around to it till now.
September 9, 2019Sep 9, 201909/9/19In this blog entry and some future ones I will be showing off functionalities that our new GC perf infrastructure provides. Andy and I have been working on it (he did all the work; I merely played the consultant role). We will be open sourcing it soon and I wanted to give you some examples of using it and you can add these to your repertoire of perf analysis techniques when it’s available.
September 3, 2019Sep 3, 201909/3/19Several years ago, we decided that it was time to support SIMD code in .NET. We introduced the System.Numerics namespace with Vector2, Vector3, Vector4, Vector<T>, and related types. These types expose a general-purpose API for creating, accessing, and operating on them using hardware vector instructions (when available).
May 15, 2019May 15, 201905/15/19Take a tour through some of the many improvements, big and small, that have gone into the .NET Core 3.0 runtime and core libraries to make apps and services leaner and faster.
April 3, 2019Apr 3, 201904/3/19If you are running Windows on a machine with 64 CPUs, you’ll need to use this feature called the CPU groups for your process to be able to use more than 64 CPUs. At some point in the far distant past,
October 9, 2018Oct 9, 201810/9/18A customer who just experienced some server outage asked us for help as they thought it was due to some very long GC pauses. I thought this diagnostics exercise might be useful for other folks as well so I am sharing it with you.
October 2, 2018Oct 2, 201810/2/18A long time ago I wrote about using Workstation GC on server applications when you have many instances of your server app running on the same machine. By default Server GC will treat the process as owning the machine so it uses all CPUs to do the GC work.
September 19, 2016Sep 19, 201609/19/16End of last year I mentioned we wanted to provide an API for you to really investigate GC/managed memory related performance called GLAD. Well, the source finally got opened source on github. So GLAD is available. The repo is called PerfView but you actually just need the TraceEvent project (but it’s much easier to just build the whole solution then add the reference to the resulting Microsoft.Diagnostics.Tracing.TraceEvent.dll).
