Helping Customers Effectively
I have to put a disclaimer here since this is not the usual type of blog posts I write. I’m by no means a master at communication. This is just what I thought that seemed to work well. YMMV of course. But I’d be very happy if they help you in some way ‘cause many of us work with customers. And I welcome your thoughts and suggestions. I have talked to customers a lot since I started working on the GC. This is in the context of helping customers to handle and resolve issues they are seeing. 1. The intention of helping should be genuine I am naturally the kind of person who wants to help with coming up with a s...
Balancing work on GC threads
In Server GC, each GC thread will work on its heap in parallel (that's a simplistic view and is not necessarily true for all phases but on the high level it's exact the idea of a parallel GC). So that alone means work is already split between GC threads. But because GC work for some stages can only proceed after all threads are done with their last stage (for example, we can’t have any GC thread start with the plan phase until all GC threads are done with the mark phase so we don’t miss objects that should be marked), we want the amount of GC work balanced on each thread as much as possible so the total pause can...

Async ValueTask Pooling in .NET 5
The async/await feature in C# has revolutionized how developers targeting .NET write asynchronous code. Sprinkle some and around, change some return types to be tasks, and badda bing badda boom, you've got an asynchronous implementation. In theory. In practice, obviously I've exaggerated the ease with which a codebase can be made fully asynchronous, and as with many a software development task, the devil is often in the details. One such "devil" that performance-minded .NET developers are likely familiar with is the state machine object that enables an async method to perform its magic. State Machines and All...
