Free. Cross-platform. Open source. A developer platform for building all your apps.
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).
May 31, 2016May 31, 201605/31/16I wrote this article in 2008 and the MSDN website no longer has it so I am making it available here. Please note that it has been quite a while and some things related to LOH have changed quite a bit.
