Somewhere around 50kqps there is a bottleneck that always requires work.

In your case, can you try setting the (undocumented) receiver-threads to 4?

Like this: receiver-threads=4
Can you also try other numbers?

In general, you will probably not be able to exceed around 100kqps because
of other reasons, but please let us know your results!
