Today is my 43rd birthday. And since there is a good chance this post will get a priority boost in your feeds, I’d like to talk about what really matters instead. Please support everything the US and EU do to help Ukraine win the war. …

A year ago I wrote a post comparing .NET 5 performance with its predecessor on Fusion performance tests, and honestly, I was quite impressed by the performance improvements in .NET 5. This year is no different: .NET 6 is truly the fastest .NET yet. First, let’s look at the same…

Ok, I wrote almost everything in the title, but let me expand on that a bit :) Fusion is 1 year old now — it was released on July 17, 2020, and interestingly, it managed to acquire more than 1K stars on GitHub during its first year. Today I published…

As you might guess, the “alien engine” is Fusion — I still struggle to find a perfect one-line description for it :) Thanks to Dmitry Filippov (̶g̶i̶r̶l̶s̶, just look at this huge pull request!), Fusion got .NET Standard 2.0 / .NET Framework 4.7+ support. Crazy, but almost every test runs…

An interesting observation I’ve made recently is that nearly all UI architectures are quite similar. Let’s start from Flux: A brief description of what happens here: Views: - Render the UI by ~ transforming the data from Stores to actual UI controls - Convert user actions to Action objects and feed them…

If you believe Virtual DOM is a “lightweight copy” of a real DOM helping to speed up the updates by batching them together— continue reading. Albeit being correct, it’s a highly misleading answer. …

This is a short overview of features added to Fusion over the last 3 months. Some of them are already covered in the Tutorial; I’ll definitely describe the rest soon. CommandR (which challenges MediatR 😎) and Operations Framework — two parts that make multi-host state sync possible. Yes, now you…

The same day .NET 5 was released I shared a single screenshot showing how much faster .NET 5 is relatively to .NET Core 3.1. I promised to share more data later — and here it is. 1. Fusion’s Caching Test — running on Ubuntu + Intel and AMD CPUs Code: https://github.com/servicetitan/Stl.Fusion.Samples , see “Caching Sample” section there. Overall, these tests stress an API…

I migrated Fusion to .NET 5 today — and honestly, I was absolutely astonished by the performance boost it brings: The output is produced by Fusion’s “Caching” sample, which uses EF Core 5 and ASP.NET Core. The speed on tests producing 20M+ operations/s (#1, #3) is mainly constrained by Fusion’s…
