Maybe the person missed the difference because how your numbers are formatted:

- OptionBenchmark.sumOptional avgt 5 2223,887 us/op

vs

- OptionBenchmark.sumOptionalValhalla avgt 5 572,833 us/op

At least to me after the first read it seemed like comparison of two similair 5kish values.

Right, it is the output from JMH (Java Microbenchmark Harness) which includes the number of non-warmup-runs before the actual score.

The original article included them as well so thought I would just post the numbers in the same format here.

I was also confused by 2223,887 us/op

Is there a missing comma or is comma being used here as a decimal point?

Comma is a decimal point, as used in many countries that aren't the United States.
