This is a guest post by Mike Rousos I recently had an opportunity to help a developer with an ASP.NET Core app that was functionally correct but slow when under a heavy user load. We found a few different factors contributing to the app's slowdown while investigating, but the majority of the issues were some variation of blocking threads that...

Improve website performance by optimizing images

Mads Kristensen

We all want our web applications to load as fast as possible to give the best possible experience to the users. One of the steps to achieve that is to make sure the images we use are as optimized as possible. If we can reduce the file size of the images then we can significantly reduce the weight of the website. This is important for various ...

I'd like to tell you about some of the recent changes we've made as part of our ongoing work to extend the optimization capabilities of RyuJIT, the MSIL-to-native code generator used by .NET Core and .NET Framework. I hope it will make for an interesting read, and offer some insight into the sorts of optimization opportunities we have our ...

Bertrand Le Roy

This post was co-written by Daniel Podder and Bertrand Le Roy. .NET Core 2.0 introduces many new optimizations that will make your code even faster. A lot of work has been done in the base class library to improve performance, but in this post, we'd like to talk about a specific category of optimization: profile-guided optimization (or PGO...

Performance Improvements in RyuJIT in .NET Core and .NET Framework

June 29, 2017 Jun 29, 2017 06/29/17

Joseph Tremoulet [MSFT]

RyuJIT is the just-in-time compiler used by .NET Core on x64 and now x86 and by the .NET Framework on x64 to compile MSIL bytecode to native machine code when a managed assembly executes. I'd like to point out some of the past year's improvements that have gone into RyuJIT, and how they make the generated code faster. What follows is by no...

Update (2017/06/12): Added BenchmarkDotNet blog post link. There are many exciting aspects to .NET Core (open source, cross platform, x-copy deployable, etc.) that have been covered in posts on this blog before. To me, though, one of the most exciting aspects of .NET Core is performance. There's been a lot of discussion about the ...

Holidays are almost upon us. Last year around Christmas time I wrote a set of GC ETW blog entries to help with diagnosing GC heap related issues. This year I want to discuss taking that a (big) step further and making an SDK that does the analysis for you using these ETW events - so before I leave for vacation I’d like to share with you ...

Allocating on the stack or the heap?

July 15, 2015 Jul 15, 2015 07/15/15

maoni

A recent discussion prompted me to write this blog entry. The question there was “when should I allocate something on the stack vs on the heap?”. I searched around and there are plenty of articles that talk about *what* gets allocated on the stack vs on the heap, but not how you should decide what to allocate on the stack vs heap. ...
