For those who like me was left wondering what DATAS is, here is the link:

Yeah, I kept scrolling to the top to see if I overlooked something.

Then I realized, "oh, it's hosted on Medium." (I generally find Medium posts to be very low quality.) In this case, the author implies that they are on the .Net team, so I'm continuing to read.

(At least I hope the author actually is on the .Net team and isn't blowing hot air, because it's a Medium post and not something from an official MS blog.)

Maoni Stephens is indeed on the .net team and is, as far as I know, the lead architect of the .net garbabe collector for many years: https://github.com/Maoni0 https://devblogs.microsoft.com/dotnet/author/maoni/

Therefore she's probably the person with the most knowledge about the .net GC but maybe not the best writer (I haven't read the article yet).

The writing itself is fine, but she’s assuming a LOT of knowledge e.g. what a GC0 budget is and what increasing it means.

I did not even know Server GC was a thing.

Did it get you curious enough to go look that up?

It did indeed! :D

Great! Same here. It was a great read overall. My current use-case won't benefit from DATAS (using Azure App Service), it's good to know this option exists though.

Actually, thinking about this more, this is super helpful for Stage VMs that are shared among multiple projects. It can help pack more instances in those VMs.

> Maximum throughput (measured in RPS) shows a 2-3% reduction, but with a working set improvement of over 80%.

I have a hard time finding this approach compelling. The amount of additional GC required in their example seems extreme to me.
