Fair enough, maybe my perceptions of .NET performance are mostly based on old versions of .NET without all the tiered compilation and other features to make JIT warmup less of an issue.

We are only just now wrapping up the conversion at work to .NET 8 from 4.8, so it will be interesting to see the performance numbers once that is complete.

Our .NET application has millions of lines of code, so JIT compilation time in particular in the old .NET could be very painful.
