The failing test is random failing test #488.

The enabled method is no actual test method but only some code measuring and printing the time required for processing operations on markers. I gues it was used around 20 years ago when implementing the functionality to get some insights into the implementation's performance. I don't see that it still has any use but may only produce maintenance effort.

I would propose to change this PR (or replace it by a new one) so that the two _testPerformance* methods in the MarkerTest class are removed. @Michael5601 maybe you want to change it accordingly?

I have added a new PR with the requested changes. (See #674)
This PR will be closed now because it has been replaced with #674.
