Looks like bimodal data, but still some increase in performance. Might be dotnet/runtime#73336.

It might be related to that some of the benchmarks triggers the new "else" statement and uses system.encoding to do utf8 encoding directly (https://github.com/Daniel-Svensson/runtime/blob/ccfb008413d9e0de738698eba7590c811f7e26fc/src/libraries/System.Private.DataContractSerialization/src/System/Xml/XmlStreamNodeWriter.cs#L389)

It the regression limited to mono? I think I saw some performance increase in another issue.

Can it be that system.text.utf8encoding is much slower on mono and if so is there any direct plan to improve that or should another "cutoff value" be chosen for mono somehow?

I might need to debug the Benchmark to get a better understanding of the actual lenghts of strings serialized to give any better feedback

Correct, it could be related to GetBytes. Might be related to #15724.

I suggest we keep the issue open to track the performance and propose for improvements.

@kotlarmilos I have made a small fix to speedup encoding where Vector128 is hardware accelerated (dotnet/runtime#85266) that might make a difference here.

I am thinking about avoiding the call to GetEncoding if Vector128 is not hardware accelerated (se mention below) as well.
Either of them might make a difference here

Thanks! I will track and inform on any perf changes.
