When copying the same file to a subdirectory of the CephFS the performance stays at 500MB/s for the whole time. MDS activity does not seems to influence the performance here.

There is a new datapoint:

When mounting the subdirectory (and not CephFS's root) the performance also degrades while staying up when writing into a subdirectory.

Is there something special at the mountpoint?
