Hi there, the author of the original post is here. PGO is disabled in .NET 6 by default mainly because of trade-offs associated w/ the startup time - and IMO it's totally reasonable assuming .NET 6 brings decent speed benefits even w/o PGO.

I turned it on mostly to show what you can expect from a service that runs for a while (more than a few minutes?) in a typical server-side scenario after migration to .NET 6 - IMO it's totally reasonable to turn PGO on for nearly any service of this kind.
