I ran the sample benchmark, where I get the DataProtector via IServiceProvider and ran multiple Protect() and Unprotect() on sample string:

// getting the data protector
var services = new ServiceCollection()
    .AddDataProtection()
    .Services.BuildServiceProvider();
_dataProtector = services.GetDataProtector("SamplePurpose");

// running the protect/unprotect
for (var i = 0; i < 1000; i++)
{
    _ = _dataProtector.Protect(LoremIpsumData);
}

The results are showing a big difference on windows against linux machines (results below).
I was launching benchmarks using crank config and perf machines. I.e. crank --config https://raw.githubusercontent.com/DeagleGross/Baraholka/refs/heads/main/Benchmarks/Benchmarks/crank/data-protector.yml --scenario dataprotector --profile aspnet-perf-lin --application.framework net10.0
